PREFACE : DOCUMENTATION OVERVIEW
About this Document
Compass™ provides an intuitive interface to the Galileo™ 616 loudspeaker management system.
Galileo is a fully digital matrix processor providing 96 kHz/32 bit resolution signal processing
for six inputs and sixteen outputs.
Galileo may be directly connected to the SIM® 3 audio analyzer, providing complete
measurement as well as control for complex audio systems. The Galileo loudspeaker
management system with the Compass control software fulfills all of the necessary signal routing
and processing between the console and the amplifier/loudspeaker.
Compass provides “snapshot” capturing of Galileo control values, allowing you to design
numerous sound processing configurations, each specific to a particular use of a venue and
subsequently available for recall at any time. Numerous snapshots may be saved as a “project”
to a workstation or laptop computer, providing backup and restoration capability, and another
level of organization.
Audience
Galileo and Compass are professional audio hardware and software. Users of the system are
sound design professionals with an understanding of sound design theory, signal equalization
design, atmospheric correction, signal delay design, and matrix mixing. This manual does not
teach sound design theory and practice.
The Galileo hardware is presumed to have been correctly installed and configured. In particular,
the Galileo must be configured with an IP address before running Compass. This process is
detailed in the Galileo Hardware Reference Manual.
Users of Compass software are assumed to be experienced computer users. Inexperienced

About Meyer Sound
Since its founding, Meyer Sound has been devoted to meeting the needs of sound reinforcement
professionals with the finest products available, the industry’s most extensive and knowledgeable
customer support, and high-level technical education.
The 1970s saw sound equipment for live performance increase in power capability, but not in
reliability or fidelity. In 1979, John and Helen Meyer established Meyer Sound to create and
support high-quality products for sound reinforcement and recording, designed to meet the
real challenges faced by audio practitioners. Today, the company’s history shows a track record
of almost 30 years of innovation, quality, performance and support.
Meyer Sound has more than 250 employees at its Berkeley, California, headquarters and satellite
offices, including one of the largest engineering staffs (in proportion to company size) in the
audio industry. International sales and support are supplied by more than half a dozen offices
around the globe. The company works closely with professionals in all areas of sound
reinforcement, gathering information on customers’ needs and providing the tools, training,
technical support and information to enable the best experience possible for sound system
users and audiences alike. Meyer Sound products are manufactured entirely at its Berkeley
factory, where high technology is combined with hand craftwork. By performing core processes
in house, the company is able to exercise the control to insure its quality standards are met
and that each unit is exactly the same as the last.
John and Helen Meyer have been personally involved with the performing arts for years, which
has given them a feeling for the role of technology in the arts. Meyer Sound is often involved
directly with the performing arts at both corporate and individual levels, locally in Berkeley and
worldwide. This is one more way that the company stays in touch with the real reason for its
existence.
COMPASS
With all the features and power offered by Galileo® 616, giving the user a comprehensive,
intuitive way to control them is paramount. Meyer Sound’s Compass software fulfills this
requirement. Running under either the Macintosh or Windows operating system, Compass
provides a graphical user interface that is the result of years of experience optimizing complex
systems.
Compass’ Galileo Map lets users see signal flow at a glance. The unique filter display shows
and allows direct editing of the composite response created by the CP-10 and TruShaping®
filters. Filter parameters can be edited graphically or by direct text or numeric entry. Seeing the

Running Compass with Virtual Galileo
Virtual Galileo provides a software simulation of the Galileo 616 hardware. It allows you to be
productive when Galileo hardware is not available for your use; it also allows you to create new
projects without risking changes to a Galileo unit that is currently in use.
Virtual Galileo is available as both a built-in component of Compass and as a stand-alone
application. The former requires no special configuration. The latter allows you to also run the
Front Panel Emulator, which provides a visual simulation of the front of a Galileo 616 with
operative buttons, status lights, and LCD panel.
The Front Panel Emulator is a good way to become familiar with the physical Galileo unit without
the risk of changing the configuration of an installed unit and to see how changes made through
Compass are reflected in the status lights and LCD panel of the Galileo 616.

Running Compass with Galileo
Although you may be able to design an entire project without making use of physical Galileo
616 hardware, at some point you’ll want to audition the sound, upload snapshots to the Galileo,
and monitor the system. Provided your network is functional, connecting your workstation to
Galileo units is simple.
Network Connections
In brief, you can connect your workstation directly to a single Galileo 616 unit, or connect your
workstation and multiple Galileo 616 units to a network switch or router.
Many modern computers support a network standard named Auto-MDIX which allows you to
connect the workstation computer directly to the Galileo without an intervening network switch
or router. With these computers, you need only plug a standard Cat-5e Ethernet cable into the
workstation and Galileo Ethernet connector. Computers that do not support Auto-MDIX may
still be directly connected to a Galileo through the use of an Ethernet crossover cable.
Adding Galileo 616 Units to Compass
Running Compass with Galileo 616 units is as easy as using the Virtual Galileo simulator:
Auto-discovery Connection of Galileo 616 Units
Select this method when the workstation computer connects to the Galileo 616 unit(s) through
its primary Ethernet port.
1. Start Compass.
2. Select the Galileos tab.
3. Click Find Galileos. Within a few seconds a list of Galileos available through the network
will be displayed.
If no Galileos are discovered you may need to choose a manual configuration as described
below.
Discovery and connection can be configured to take place when Compass starts up. See

COMPASS USER GUIDE
Manual Connection of Galileo 616 Units
Select this method if auto-discovery fails to detect your Galileo 616 units or if the workstation
computer is using a secondary Ethernet port to connect to the Galileo network.
Prerequisite: using the front panel controls of the Galileo 616 units, record the IP address of
each unit. See the Galileo Hardware Reference Manual for details.
1. Start Compass.
2. Select the Galileos tab.
3. For each Galileo in the network:
a. Click Add Galileo. A settings window will be displayed.
b. Provide the IP Address for the Galileo unit. If you also provide a Galileo Nickname
and/or Tab Name, the Galileo will be renamed; if you leave these fields blank, Compass
will retrieve the name from the Galileo 616 unit.
c. Click OK. The Galileo 616 unit will now listed in the main window.
d. If necessary, click Refresh to detect the Galileo connection.
You may now click Connect to establish a links to the Galileos.
Troubleshooting Galileo 616 Connections
Compass communicates with Galileo 616 units using TCP/IP ports 15001 and 15002. If you
have enabled a firewall or other access-restriction software on your workstation, or are connected
to the network using a router or switch, you may need to configure their security settings to
permit use of these ports. In addition, permitting access to port 8000 on the Galileo 616 units
will allow web access to the Galileo log files.
Compass auto-detection of connected Galileo 616 units is restricted to the primary Ethernet
port. If connections are made through alternate ports, connections must be configured manually.
The workstation operating system may also need to be manually configured to enable the
alternate Ethernet port.
If connecting directly to a Galileo 616 unit, your workstation may require the use of a crossover
Ethernet cable.

CHAPTER 2: COMPASS OVERVIEW
In this chapter you will learn how more about the types of tools Compass provides you, as well
as gain some insight into the relationship between Compass and Galileo.
Compass Capabilities
Compass provides comprehensive control of the Galileo 616 through a graphical user interface
running on a remote computer.
Compass is the primary method of operating the Galileo loudspeaker management system.
The software enables easy access to all Galileo features and even provides control of multiple
units. Compass includes a context help system, full copy and paste of all settings and groups
of settings, and multiple levels of undo. The tabbed interface can be scaled to any display
resolution and the colors can be configured for either day or night. Windows and Mac OS X
versions have the same user interface so that switching between platforms is completely
transparent.
A sophisticated channel linking system allows multiple input and outputs, even on multiple
Galileo 616s, to be linked so that parameter changes can be applied to all linked channels.
Relative gain mode allows gain changes to linked channels while retaining gain differences
between linked channels.
The EQ Plotter window includes an overlay display of the applied CP-10 and TruShaping
equalization, for both amplitude and phase, in a single editable window. Equalization parameters
can be edited directly by simply dragging EQ points in the display, or by entering values
numerically for greater precision.

CHAPTER 2: COMPASS OVERVIEW
Compass Controls
Figure 2.1. Illustrated User Interface Element Names
On each Compass page are controls for setting values; selecting, isolating, and link grouping
channels; enabling or bypassing parts of the signal path; selecting a page or sub-page of
controls; adjusting the display of components; saving snapshots and projects; and so on.
Some pages appear to be very complex, but as with physical consoles there is a large duplication
of controls, each specific to a channel or band. Color is used to indicate the status or setting
of controls, and many controls are likely to be familiar to you already, either as parts of a
traditional console or as a variation of a common graphic interface control.
The following sections discuss the major controls in more detail:
Using Tabs
Compass organizes its controls on “pages,” which are selected by
choosing a “tab.” Visually, these tabs look similar to the tabs used
in binders and books: an extra bit of the page that sticks out beyond the normal page edge,
with a label. Selecting the tab displays the page.
When a tab is clicked the page is changed immediately after the mouse button is released. If
you move the mouse off the toggle button, the action is canceled.
10
Download from Www.Somanuals.com. All Manuals Search And Download.
COMPASS USER GUIDE
Some pages have tabs within the page itself, providing access to a series of sub-pages that
further organize controls. On the Input Processing and Output Processing pages these tabs
can be hidden or the sub-pages collapsed, freeing up additional space for the plot curve display.
The color of the tab indicates the network status of the Galileo unit. Working Galileos have a
blue tab; disconnected Galileos have a red tab. If there are network communication errors, the
tab will turn yellow and, if the network is in a stall condition, magenta.
Throughout this guide the selection of tabs is indicated as a sequence: Compass > Compass
Preferences indicates that the Compass tab should be selected, followed by the Compass
Preferences tab. This convention is sometimes extended to include the name of a specific
control or group of controls within the page.
When directing you to a page that is specific to a particular Galileo unit the name of the unit is
not included: for instance, the [Galileo Unit] > Input Processing > Parametric EQ page is a
sub-page of a specific Galileo, but this manual cannot know in advance what name you have
given the Galileo: you will need to click the name of that Galileo before clicking the Input
Processing tab.
Using Value Boxes
Value boxes provide a place to type a name or number to set a value.
Visually, the value box is presented as a raised box containing the name or
value of the setting. Clicking in the box places the text input cursor — a
blinking vertical bar — in the box.
With the default setting of Compass > Compass Preferences > User
Interface Display and Control Options > Select All Text When Entering
Text Field, the value is automatically selected: typing will immediately replace the value. If this
setting is cleared, typing will be inserted at the cursor.
Pressing ‹ Enter › or ‹ Return › sets the new value. If ‹ Esc › is pressed instead, the original value
is restored. You can also use ‹ Cmd+Z › to undo changes.

CHAPTER 2: COMPASS OVERVIEW
Using Buttons
Buttons perform an action when pressed, perhaps selecting a
channel, toggling a function, or displaying a new page. Visually,
the buttons look like traditional on-screen buttons.
Buttons almost always have a label (unassigned Link buttons
are the notable exception); this label may change to indicate the status of the underlying function:
clicking a “Bypassed” button will change it to “Enabled,” for instance. Also of note, the Galileo
Map page has processing buttons that display a miniaturized version of the EQ plot: clicking
the button takes you to the appropriate processing page.
When a button is clicked the action is performed immediately after the mouse button is released.
If you move the mouse off the button, the action is canceled: the click and release must occur
on the button for the action to take place.
Using Toggles
Toggles are a type of button, choosing an “on” or “off” setting for
a preference. Visually, toggles look like back-lit mechanical
switches, glowing when the toggle is “on.”
When a toggle is clicked the setting is changed immediately after
the mouse button is released. If you move the mouse off the toggle
button, the action is canceled.
Using Selectors
Two types of selectors are used in Compass. The first is a “option
selector” which acts like the buttons on a automobile radio: only one
station can be active at a time. The second is a “drop down” selector
which acts like a menu: clicking the button displays a list of choices,
one of which can be selected.
Visually, the option selector looks like a round button which glows
when selected. The drop-down selector looks like a button, labeled
with the active setting, and has an arrow at the right end indicating other choices are available
for selection.

COMPASS USER GUIDE
When an option selector is clicked the setting is changed immediately after the mouse button
is released. If you move the mouse off the button, the action is canceled.
When a drop-down selector is clicked a vertical list of choices is immediately displayed. The
mouse button must then be released so that you can click your selected choice. When the
mouse button is released the second time, the list disappears and the selected choice is
displayed as the selector button label. In the example above, the “Layout” drop-down selector
is showing its normal state, while the “Order” selector has been clicked and is presenting a list
of choices.
Using Encoders
Gain, delay, and frequency value boxes are accompanied by a rotary encoder
control. This gives you the choice of using a mouse to set the value instead
of typing the value directly. Visually, the encoder looks like a round knob
inside a square casing. When the knobs are colored the colors correspond
to the colors of the Galileo 616 front panel encoders.
Unlike the controls described so far, the encoder is used by dragging: click and hold the mouse
button, then drag the cursor around to change the value in the value box. The location of the
click determines the rate of change: clicking the center of the knob displays a x10 label beside
the cursor, indicating that mouse movements will result in larger value changes, while clicks
further from the center will result in smaller value changes.
In addition to fine and coarse movement, encoders can respond to circular movements or linear
movements dependent on the Compass > Compass Preferences > User Interface Display
and Control Options > Value Controller Type preference. In Encoder mode, the cursor must
travel around the encoder, as if turning it with one’s fingers. In Joystick mode, the cursor is
dragged horizontally or vertically to adjust the value, as if the encoder were a slider.
Another behavior variation is selected by the Compass > Compass Preferences > User
Interface Display and Control Options > Input Device Type preference, which modifies the
behavior of the cursor when the mouse button is released. In Mouse mode, the cursor remains
in place when the button is released. In Tablet mode, the cursor returns back to the encoder.

CHAPTER 2: COMPASS OVERVIEW
Using Faders
Faders are shown on the input and output master pages. Visually, they look like
traditional physical console faders: a slider that can be dragged up or down to
adjust the gain value, with value demarcations beside it. The gain value is
displayed in both the associated value box and on the slider knob.
A subtle feature of fader sliders is found in the ability to click a number label to
jump the slider to that exact value: clicking the -3 label will set the gain to -3 dB;
clicking the −∞ label will set the gain to full attenuation. As well, clicking above
or below the slider knob will adjust the gain value up or down by one decibel.
Using Meters
Meters are shown on several pages; some meters are displayed vertically,
others horizontal. Visually, they look like traditional VU meters. The signal
level may be shown on the meter, as per the Compass > Compass
Preferences > User Interface Display and Control Options > Show Meter
Values preference.
When clipping occurs the meter is highlighted in a red box. By default this
clipping indicator is active only when clipping is occurring. This behavior may be changed using
the Compass > Compass Preferences > Clip Indicator Clear Mode preference. When clipping
indication is set to be held, clicking the meter will clear the indicator.
Clipping occurs at -0.5 dB on the meters: this corresponds to the signal voltage level selected
by the [Galileo Unit] > Settings > Input and Output voltage range preferences (+26 dBu by
default, configurable to +20 dBu for studio mode use).
NOTE: The clipping indicator is set at a true -0.5 dB. The clipping indicator is not a
pre-warning that clipping may occur: it indicates that clipping is actually happening.
Using Parametric EQ Handles
The Parametric EQ plot displays “handles” for the available EQ
bands. Visually, these appear as numbered squares, with the
numbers corresponding to the bands displayed on the
14
Download from Www.Somanuals.com. All Manuals Search And Download.
COMPASS USER GUIDE
Parametric sub-page. When the mouse is hovered over a handle, an expanded handle is
displayed: three vertical bars intersecting a horizontal bar.
The horizontal bar, amber in color, corresponds to the gain level. The center vertical bar, red,
corresponds to the frequency centerpoint. And the two outside vertical bars, blue, correspond
to the bandwidth.
Dragging a bar will adjust only the corresponding value: for example, if you wish to adjust
frequency without adjusting gain or bandwidth, drag the red bar.
Dragging a crosspoint will adjust two values simultaneously: for example, if you wish to adjust
both frequency and gain, drag the crosspoint of the red and amber bars.
Pressing ‹ Alt › before clicking will remove the red bar, replacing it with a single blue bandwidth
bar; you can then adjust bandwidth and gain simultaneously, or select either bar to adjust
bandwidth or gain in isolation.
Using TruShaping EQ Bars
The TruShaping EQ plot displays “bars” for the available EQ bands. Visually,
these appear as horizontal and vertical bars, with large handles where the bars
connect.
Each horizontal bar may be dragged to adjust one of four gain settings; each
vertical bar dragged to adjust one of three frequency settings. The large handles
may also be dragged, adjusting a gain and frequency setting simultaneously.
Using the File Selector
The file selector is used to save and load snapshots
and projects. It provides file selection functionality:
a Look In drop-down selector used to select parent
directories; a quick-selection box with computer and
storage device names; a file list box showing the
contents of a directory; and a File name value box
in which to name the file that is to be loaded or
saved.

CHAPTER 2: COMPASS OVERVIEW
In the upper right, navigation arrows allow you to easily go up the directory tree or back to a
previous directory; an icon of a folder will create a new folder within the current directory; and
the rightmost icons choose how the file list is displayed.
At the bottom, the Files of Type box shows the type of file Compass wants to load or, if saving,
the extension that will be appended to the File name.
Compass remembers the last directory you used; often, you will do little more than type a new
file name (when saving) or select an existing file name (when loading, or to overwrite a file when
saving). If you save your files alongside the stock Compass example files, you’ll use the “up
directory” arrow to navigate a shallow directory tree, moving up from a storage directory to a
parent directory, then double-clicking a directory name to move down into the directory in
which the file you want is stored, or to save your file.
If saving files to a USB memory stick, select the USB memory stick device in the quick-select
box on the left, provide a File name, and click Save. If loading a file, select a name in the list
of files and click Open.
NOTE: File selection windows are not affected by your choice of dark or light color
scheme: they are always bright. Please be aware of this when planning project file
changes during a performance.
General Workflow
The following steps outline a typical Compass workflow.
1. Configure Galileo
The natural first step when working with Compass is to configure the software to match the
connected hardware. The Galileo 616 supports six channels of input and sixteen channels
output. Inputs may be single-channel analog signal or two-channel AES digital signal; outputs
are analog signal capable of driving Meyer Sound self-powered loudspeakers directly. Voltage
for analog inputs and outputs can be set to +26 dBu (standard) or +20 dBu (studio mode).
The Galileo 616 also has a standard Ethernet connection for communication with Compass. In
facilities with more than one Galileo, the Ethernet connections will be made to a network hub
or router, allowing Compass to communicate with all Galileos simultaneously. Where there is
only one Galileo, the Compass workstation may be connected directly to the Galileo.

COMPASS USER GUIDE
Audio input/output configuration is managed through the [Galileo Unit] > Settings > Input
Network configuration is managed through the Galileos page. Find Galileos will, in most
situations, auto-discover network-connected Galileo 616 units. Detailed instructions are provided
2. Label Galileos, Inputs, and Outputs
Although most Galileo installations are relatively simple, it is still important to provide useful
names for the Galileos and their input and output channels. Naming helps reduce errors and
speeds the design process.
Galileo naming can be done through the Galileos page: simply select the Galileo Nickname
and type a new name. The tab name will be automatically updated to match the nickname;
when the tab name is too long, you may wish to select it and type a new, shorter tab name.
Please keep in mind that the front panel display on Galileo units can display about a dozen
letters in a channel name, and only alphanumeric characters A-Z, a-z, 0-9. If users will be
managing the Galileo using its front panel, make sure the most important information is at the
start of the name.
Channel naming can be done through the [Galileo Unit] > Galileo Map page. Select the Label
and type a new name for the channel. The new name will be used on all other pages
automatically.
In addition to providing names for the Compass interface it is also useful and wise to label the
signal cables themselves. Should it be necessary to replace a Galileo unit, or if someone
disconnects the cables, correct reconnection is simple when the Galileo ID and channel ID are
attached to the cable end.
3. Routing
After labeling you will probably want to route inputs to outputs so that you can begin setting
gains and processing values while auditing the signal aurally and/or through a SIM3 analyzer.
Routing is done through the [Galileo Unit] > Summing Matrix page.
17

CHAPTER 2: COMPASS OVERVIEW
A number of preset matrices ship with Compass and may be useful as a launching point for
developing a new project. Alternatively, you may wish to enable Router Mode on the Summing
Matrix page, to quickly map out the paths, and then clear the mode for fine-tuning the signal
levels. For any moderately complex system you will send an input to multiple outputs: for
instance, several input channels will likely be routed not only to their corresponding left or right
loudspeaker arrays, but also to a combined subwoofer output on which you’ll configure a high
pass filter.
4. Initial Gains
With inputs routed to outputs, you can now start to adjust signal gains. If you work best with
access to the full suite of controls, the [Galileo Unit] > Galileo Map page is where you’ll do
this task. If you’re more comfortable with traditional consoles and faders, you’ll probably prefer
the [Galileo Unit] > Input Masters and [Galileo Unit] > Output Masters pages.
In either case, you’ll probably make use of Select, Isolate, and Mute as you start configuring
Although the Galileo 616 has a very low noise floor and wide dynamic range it is best to work
the mixing console at its optimum levels. The Galileo will accept the maximum output of most
mixing consoles, allowing you to restrict gain control in the Galileo to the adjustment and
balancing of signals. This will provide you maximum flexibility and the best audio quality.
5. Link Groups
Once the loudspeaker gains are balanced, it is useful to create sets of link groups that can be
used to duplicate changes across multiple channels simultaneously. Judicious use of link groups
will both speed the development of system configurations and reduce errors by ensuring all
associated channels are updated without further effort.
Link groups can operate in one of two modes. In the default mode, link groups simplify the
selection of multiple channels before adjusting a control; in its optional mode, link groups
Channel Linking Preferences (p. 76) for options that influence the behavior of selects, link
groups, and linked Galileos.
18
Download from Www.Somanuals.com. All Manuals Search And Download.
COMPASS USER GUIDE
You may configure link groups through the [Galileo Unit] > Settings > Link Groups page. First
determine which channels will share identical settings: these are the channels you’ll wish to
assign to a common link group. When this is done you will be able to adjust the same control
on multiple channels simultaneously, either by selecting a channel in the group and then adjusting
the control (default mode); or by adjusting the control in a channel that belongs to the link group
(alternative mode).
Note that control value changes can be replicated as absolute or relative changes. See Choosing
Absolute or Relative Linked Channel Gain Control Changes (p. 45) for usage details.
6. Atmospheric Correction and Array Correction
Before fine-tuning loudspeaker outputs, atmospheric correction and array correction should
be configured. Atmospheric correction takes into account environment conditions and
loudspeaker distances to correct for high-frequency attenuation. Array correction mitigates
low- and mid-frequency build-up due to coupling effects in loudspeaker arrays.
Atmospheric correction is calculated using temperature, humidity, altitude, and loudspeaker
distance. The first three variables are assigned on a per-Galileo basis, on the [Galileo Unit] >
Settings > Environment page; the latter on a channel-by-channel basis, on the [Galileo Unit]
> Output Processing > Channel Settings pages.
Array correction is available for Meyer Sound M Series arrays. Highly-tuned EQ curves have
been developed for each particular M Series product. Array correction configuration is managed
on the [Galileo Unit] > Settings > Array Correction page.
These settings can create very large changes in gain level across parts of the signal frequency
range. Before using atmospheric and array correction, be sure you understand when and how
7. Connect SIM3
The Meyer Sound SIM-3022 Audio Analyzer is used to quickly and accurately measure the
frequency, phase response, and signal-to-noise ratio of components in the acoustic signal path
for all combinations of inputs and outputs. It is a superlative tool for determining optimal
loudspeaker placement and appropriate acoustic environment correction. When connected to
a Galileo 616, the Galileo is used as a line switcher, eliminating the need for any additional
patching.

CHAPTER 2: COMPASS OVERVIEW
SIM3 User Manual for full details.
8. Configure Processing
Compass provides first-order EQ (TruShaping) and second-order EQ (parametric) equalization
on input and output channels, as well as a 31-band graphic equalizer on inputs and high/low
pass filtering on outputs. TruShaping allows you to shape frequency response with a minimum
of phase shift; parametric helps in reducing interaction artifacts; and the low/high pass filters
are often used in creating subwoofer feeds.
9. Create Project and Snapshots
As you finalize the settings for a given source type you will want to capture a “snapshot” of the
input, output, and summing matrix control values. Once captured, a snapshot can be recalled
at will: when it is recalled, all the controls are set to the values they had when the snapshot was
captured, recreating the aural environment you designed.
An additional level of organization is provided by “projects,” which allow you to save and load
a set of snapshots for subsequent recall. Projects can be particularly useful as a means of
collating a base set of snapshots from which to develop site-specific snapshots; or to organize
snapshots by act, venue, or other arbitrary measure. Projects also save Galileo settings and
Compass preferences, restoring your user interface and network preferences when loaded.
Snapshot, project creation, and update buttons are available at the bottom of most pages;
and Loading Projects and Snapshots (p. 61) for further details.
10. Restrict Access
In those situations when you are creating snapshots for a facility installation, where snapshots
will be recalled by multiple users, you may want to lock down access to the Galileo front panel
controls and Compass control pages: in all likelihood, you will want to provide access to only
snapshot recall and environment settings. Access control gives you this ability.

In other situations you may be responsible for designing the signal processing components of
a show, but the show itself will be run by a someone else; in such a case, you may want to
allow access to gain control and the summing matrix while locking-out access to signal
processing.
Compass provides access restrictions for twenty-eight types of controls and functions. Access

CHAPTER 3: USING COMPASS TOOLS
Navigating the Tabbed Window Interface
Compass is presented as a single-window interface controlling a number of physical and virtual
Galileo 616 units. Within the window each Galileo is provided its own “tab.” Clicking a tab brings
that page to the front of the window, often presenting a series of sub-tabs classifying various
sets of controls: “Settings,” “Input Processing,” “Output Masters,” and so on.
In this user manual, pages are generally identified by listing the tabs and sub-tabs that must
be selected to reach the page. If the instructions say “Select the [Galileo Unit] > Input
Processing > Parametric page for the Galileo,” the intention is that you click the tab for the
Galileo you wish to work with, then click the Input Processing tab, and then the Parametric
sub-tab.
In addition to the tabs associated with specific Galileo 616 units or Virtual Galileo simulations,
a tab labelled Compass allows you to set various interface preferences and a tab labelled
Galileos contains controls for finding and connecting Galileo units.
On each page a variety of controls offer the ability to adjust the signal path. In this user manual
control titles and control names are written in bold text, like so: “In the Current Project box,
click Save As…”. If the instructions include setting a specific value, that value is indicated using
monospace (typewriter) text: “Set Delay to 20ms.” Finally, where instructions reference a
special keyboard combination, the key names are given special treatment: “When using the
keyboard, use ‹ Shift+Enter › to set the value after typing it.”
NOTE: Macintosh and Windows keyboards may use different names for the modifier
keys.

CHAPTER 3: USING COMPASS TOOLS
Using Shortcuts
To facilitate rapid Compass configuration a number of shortcuts are available:
Linking Settings Between Stereo Pairs
Assuming that neither channel of a stereo pair is isolated, a stereo pair of control values can
be adjusted simultaneously:
■
When using the mouse, hold the ‹ Shift › key when dragging or clicking a control.
■
When using the keyboard, use ‹ Shift+Enter › to set the value after typing it.
Linking Settings for All Channels on a Galileo Unit
A control value can be set for all non-isolated channels simultaneously:
■
When using the mouse, hold ‹ Shift+Cmd › when dragging or clicking a control.
■
When using the keyboard, use ‹ Shift+Cmd+Enter › to set the value after typing it.
The set of all input or all output channels on the Galileo that are not isolated will now share the
same control value.
Isolating a Single Channel
When multiple Selects are enabled, changing the value of a control for one selected channel
normally changes it for all selected channels. To momentarily override this behavior:
■
When using the mouse, hold ‹ Cmd › when dragging or clicking a control.
■
When using the keyboard, use ‹ Cmd+Enter › to set the value after typing it.
Switching Between Absolute and Relative Gain Control Adjustment
The default behavior of linked channel gain adjustment — absolute or relative value
change — can be overridden using the keyboard:
■
When using the mouse, hold ‹ Alt › when dragging or clicking a control.

COMPASS USER GUIDE
■
When using the keyboard, use ‹ Alt+Enter › to set the value after typing it.
Preferences (p. 76) for more detail.
Automatic Negative Gain Values
When typing a value in a gain value input box the default behavior for Compass is to assume
the value is negative unless preceded by a plus: for example, typing 2in a gain value box will
set the gain to −2 dB. Type +2to set the gain to +2 dB. This behavior can be changed; see
User Interface Display and Control Options (p. 72) for details.
Setting Full Attenuation Gain Values
When using the keyboard, type -i, -inf, or a value less than -60to set gain to full attenuation.
Arithmetic in Gain Value Controls
Gain value boxes support addition and subtraction through the keyboard:
■
To increase a value by an amount, precede the value with double-plus: for example, typing
++2in a gain value box will increase the value by two decibels.
■
To decrease a value by an amount, precede the value with double-minus: for example,
typing --6in a delay value box will decrease the value by six decibels.
The normal behavior of a gain value box is to accept the value as an absolute: typing +2in a
gain value box sets the value to 2 dB; typing -6in a gain value box sets the value to −6 dB.
Rapid Fader Values Changes with the Mouse
■
Click a numeric value to the right of the fader slider to directly set common integer values.
■
Click above or below the fader slider to increment or decrement the value.
Fine and Coarse Rotary Encoder Value Changes with the Mouse
■
Click the center of an encoder before dragging to boost value change speed by a factor
of ten. The pointer will display 10x to indicate values will change rapidly.

CHAPTER 3: USING COMPASS TOOLS
■
Click outside the center of an encoder before dragging to change values less rapidly.
Setting Frequency Values
When typing a frequency value, the values 1500, 1.5k, and 1k5are equivalent.
Tabbing Between Input Boxes
The ‹ Tab › key will jump the input cursor from input box to input box. This can make it remarkably
quick and easy to configure controls; on the Input Masters page, for example, one can tap
‹ Tab, Tab › to jump from channel name box to channel name box (skipping the value box),
renaming them en masse without one’s hands leaving the keyboard.
Tabbing Between All Controls
The ‹ Tab › key can be configured to allow keyboard control of buttons as well as input boxes.
By default, tab jumps only to value input boxes; to change this behavior to include buttons:
■
Select the Compass > Compass Preferences page and clear Disable Keyboard Control
of Buttons.
Reset to Default
To reset a value box to its default, type ✱ (asterisk).
Undo/Redo
A thousand levels of Undo are available.
■
To undo a change, press ‹ Cmd+Z ›.
■
To redo a change after undoing it, press ‹ Shift+Cmd+Z ›.

Using Small Screen Scaling
If your computer has a low-resolution screen, Compass control pages may not fit on the screen
at its default size. To remedy this:
■
From User Interface Display and Control Options, select a User Interface Scale that
allows the Compass window to fit your screen.
When you reduce the user interface scale, the control handles on equalizers may become too
small to be useful. To counter this:
■
From User Interface Display and Control Options, select a Plotter Control Handle Scale
that will negate the reduction.
Show Meter Values on Meters
From User Interface Display and Control Options, enable Show Meter Values.
Retain Meter Clipping Indicator
By default the clipping indicator is on only for the duration of an over-signal event. To change
this:
■
From Clip Indicator Clear Mode, select a time-out option or select manual clear.
Connect Compass to Galileos On Start-up
To have Compass search the network for Galileos and connect to those Galileos and Virtual
Galileos which were active when Compass was last used, as well as listing all discovered
Galileos, set the following Startup Galileo Discovery and Connection Options:
■
Enable Find Available Galileos on startup.
■
Enable Relaunch and reconnect to previously connected Virtual Galileos on startup.
■

CHAPTER 3: USING COMPASS TOOLS
Clear Selected Channels on Galileo Switching
Compass normally retains channel selects for each Galileo page, so that when you return to a
page the previously-selected channels are still selected. If you prefer to have channel selects
automatically cleared when leaving a Galileo page:
■
From Channel Linking and Select Options, enable De-select all channels when the
active Galileo tab changes.
Change Linked Gain Controls by Relative Amounts
When you set a new value in a gain control on a selected channel, the default behavior is to
change the value of all linked channels to that same value (“absolute” mode: changing a -10 dB
control to -8 dB sets the linked gain controls to -8 dB). If you would rather have the other
channels changed by the same amount (“relative” mode: increasing a -10 dB control to -8 dB
increases linked gain controls by +2 dB):
■
From Gain Control Linking Mode, enable Linked Channel Gain changes are relative
by default, use ALT for absolute.
Include Isolated Channels in Channel Linking
Value changes propagated through channel linking skip isolated channels by default. If you’d
rather the (selected) isolated channels were included:
■
From Isolate Linking Behavior, enable Isolated channels will be included when linking
from another channel.
Configuring Audio Inputs and Outputs
Each Galileo 616 unit can receive six channels of audio input signal and send sixteen channels
of output signal. The Galileo 616 can accept the line level output of most mixing consoles and
can directly drive Meyer Sound self-powered loudspeakers to full output.

COMPASS USER GUIDE
Configuring the Galileo 616 for Analog Audio Input
Determine the maximum signal level before configuring the Galileo. Selecting an input voltage
range that is too low can result in increased noise levels depending on your power and grounding
infrastructure. +20 dB is mainly for Studio applications, +26 dB is for all other types of
applications.
1. Select the [Galileo Unit] > Settings > Input and Output page.
2. Clear Enable Linking Across Selected Galileos to avoid configuring other Galileos.
3. Set Input Channel Types to Analog for the appropriate input channel pairs.
4. Select the appropriate Input Voltage Range for the input source.
Configuring the Galileo 616 for Digital Audio Input
Note that AES connections are made to ports A, C, and E. The companion ports (B, D, and F)
must be left unconnected.
1. Select the [Galileo Unit] > Settings > Input and Output page.
2. Clear Enable Linking Across Selected Galileos to avoid configuring other Galileos.
3. Set Input Channel Types to AES for the appropriate input channel pairs.
AES input does not require selecting an input voltage range.
Configuring the Galileo 616 Audio Outputs
The adjustable output range provides two level output settings to drive Meyer Sound
self-powered products. The +20 dBu output range setting lowers the overall noise floor by
nearly 6 dB. However, this setting makes the Galileo output signal more vulnerable to defects
in the overall grounding system. The actual improvement attained depends on the quality of
the grounding between components. For this reason the default setting is +26 dBu.
In either setting, the digital gain will compensate for either analog output gain setting, so that
the overall system output level set in the Galileo will remain the same.
1. Select the [Galileo Unit] > Settings > Input and Output page.

2. Clear Enable Linking Across Selected Galileos to avoid configuring other Galileos.
3. Select the appropriate Output Voltage Range for the connected devices.
Configuring Many Galileos Simultaneously
When you have several Galileo 616 units with identical I/O requirements, you can configure
them simultaneously.
1. On the Galileos page:
a. In the Link column, select the Galileos that will be configured identically.
b. In the ID column, assign the selected Galileos the same link ID.
2. Select a [Linked Galileo Unit] > Settings > Input and Output page.
3. Select Enable Linking Across Selected Galileos. The page background color will change
to dark purple (magenta).
4. Configure the Galileos as described in the previous procedures.
All globally linked Galileos will now have the same I/O configuration.
Using the Summing Matrix
The Summing Matrix is analogous to the matrix component of a standard physical mixing
console, where input channel rows are directed to output channel columns. Each crosspoint
can be fine-tuned from full attenuation to +20 dB gain.
Using the Summing Matrix as a Signal Router
Signal routers do not adjust signal level as the signal is routed from inputs to outputs. Each
crossover point is a simple switch, selecting full attenuation (off) or unity gain (on).
1. Select the [Galileo Unit] > Summing Matrix page.
2. Select Router Mode, located at the top left of the page.

3. For each input that is to be routed to an output, click the crossover point to select unity
gain. Input signal will be routed to the output channel at unity gain.
Crossover points may still be assigned an arbitrary crossover attenuation value. Click inside
the crosspoint value box and type a new value, then press ‹ Enter › to set the value.
Creating a Custom Summing Matrix
The greatest power of the matrix is its ability to route an input channel to several output channels
simultaneously at varying signal levels, combining sources and helping diminish sound
localization.
1. Select the [Galileo Unit] > Summing Matrix page.
2. Clear Router Mode, located at the top left of the page.
3. For each input that is to be routed to an output, assign an attenuation value to the
crosspoint. You may adjust the level of the combined signal using the Output Masters
controls, while adjusting the relative level of each input source using the Summing Matrix
controls in the output channel column.
Resetting Matrix Values
1. Right-click on a crossover point: either the crossover point you wish to reset, a crossover
point on a row you wish to reset, or on any crossover point if you want to reset the entire
matrix. The Clipboard Options and Saved Settings window will be displayed.
2. Select the appropriate Reset. The button row labeled Matrix Gain corresponds to the
specific crossover point, Matrix Input Row to the row, and Summing Matrix to the entire
matrix.
NOTE: Channel selects and global Galileo linking can result in other matrix controls
also being reset. The Clipboard Options and Saved Settings window provides a
list of linked Galileos and channels.

CHAPTER 3: USING COMPASS TOOLS
Linking Channels
You may want several channels to share the same settings. For instance, stereo pairs almost
always have identical processing, and loudspeakers are almost always in the same environment
and should share the atmospheric correction settings.
There are two link modes: one that uses the ‹ Shift › key to set the value of a stereo pair; and
one that uses the Select buttons to set the value of an arbitrary selection of channels.
Linking Settings Between Stereo Pairs
Assuming that neither channel of a stereo pair is isolated, a stereo pair of control values can
be adjusted simultaneously. On the input side, A+B, C+D, and E+F provide three stereo pairs;
on the output side, 1+2, 3+4, … 15+16 provide eight stereo pairs.
■
When using the mouse, hold the ‹ Shift › key when dragging or clicking a control.
■
When using the keyboard, use ‹ Shift+Enter › to set the value after typing it.
Linking Settings for All Channels on a Galileo Unit
A control value can be set for all non-isolated channels simultaneously:
■
When using the mouse, hold ‹ Shift+Cmd › when dragging or clicking a control.
■
When using the keyboard, use ‹ Shift+Cmd+Enter › to set the value after typing it.
The set of all input or all output channels on the Galileo that are not isolated will now share the
same control value.
Linking Arbitrary Channels via Select
Channels with enabled Selects are linked: changes to a control on one of the selected channels
will change all selected channels simultaneously.
1. Enable Select for the channels that are to share the setting; clear Select or enable Isolate
for those channels that are not to be linked.
Selected channels have a dark green (light green) background.

2. Make your control setting changes. All selected, non-isolated channels are linked and will
share the control setting value.
Select linking can be momentarily disabled by holding the ‹ Cmd › key when mousing or using
‹ Cmd+Enter › when entering a control value.
Select and link groups.
Selecting Many Channels Simultaneously (Link Groups)
Mass selection of channels is possible through the use of link groups. When using link groups,
enabling and clearing Select for a channel will simultaneously enable or clear Select for all
channels in the link group. Up to three groups of input channels and eight groups of output
channels may be configured. Isolated channels can be excluded or included in link group
selections, depending on a preference setting.
1. Select the Compass > Channel Linking Preferences page.
2. Set Link Groups and Selects Mode to Selected channels are always selected in groups
in part of an enabled Link Group.
3. Set Isolate Linking Behavior:
■
Select Isolated channels will not be included when linking from another channel
if you want isolated channels to be excluded from link group selection unless the
isolated channel is specifically selected.
■
Select Isolated channels will be included when linking from another channel if
you want isolated channels to be included in link group selection, so that clicking any
channel in the group results in the isolated channel also being selected.
4. Select the [Galileo Unit] > Settings > Link Groups page.
5. Assign the appropriate channels to a single link group. Enable that link group.
Linked channels have a dark blue (light blue) background.
Linking behavior can be momentarily disabled by holding the ‹ Cmd › key when mousing or
using ‹ Cmd+Enter › when entering a control value.

CHAPTER 3: USING COMPASS TOOLS
Separating Select and Link Group Behaviors
By default link groups are used to enable selection of many channels simultaneously, as
described above.
An alternative behavior is available in which the channels in a link group are linked regardless
of their select status. This allows you to create two levels of channel linking: one of channels
linked by their Select status, and one of channels linked by their Link group.
1. Select the Compass > Channel Linking Preferences page.
2. Set Link Groups and Selects Mode to Enabled Link Group channels are linked
independently and in addition to selected channels.
3. Set Isolate Linking Behavior:
■
Select Isolated channels will not be included when linking from another channel
if you want isolated channels to be entirely excluded from link group control linking.
■
Select Isolated channels will be included when linking from another channel if
you want isolated channels to be included in link groups control linking. Changes made
to controls in the isolated channel will not effect changes in other channels, but changes
in other channels in the link group will effect changes in the isolated channel.
4. Select the [Galileo Unit] > Settings > Link Groups page.
5. Assign the appropriate channels to a single link group. Enable that link group.
Linked channels have a dark blue (light blue) background.
Linking behavior can be momentarily disabled by holding the ‹ Cmd › key when mousing or
using ‹ Cmd+Enter › when entering a control value.
Quickly See Which Channels Are Linked
Channels belonging to a link group have a dark blue (light blue) background; channels which
are actively selected have a dark green (light green) background. While these colors provide
visual feedback that a change to a control is going to effect changes in other channels, you
may want to know precisely which channels are going to change. The following procedure will
assist:
44

COMPASS USER GUIDE
■
Right-click the control before adjusting it. The Clipboard Options and Saved Settings
window will be displayed. Below the name of the channel and the control is a graph of
Galileo units: those channels that are shown as buttons are linked and will be affected by
the control setting change. Those channels that are dimmed will not be affected.
In the example to the right, three Galileos are linked.
A change to the output polarity on Foyer channel
five will result in the same change being applied to
six other channels (Main Unit channels 4–6, Fill
channels 3–5).
Choosing Absolute or Relative Linked Channel Gain Control Changes
When a gain control is adjusted, linked channels are affected by the change. There are two
ways the change can be propagated to the other controls: as an absolute value, so that all
affected channels are set to the same value; or as a relative change, so that all affected channels
are adjusted by the same amount.
In absolute mode, if you had linked gains at -4, -12, and -18 dB, and set one gain to 0 dB, all
three gains would be set to 0 dB.
In relative mode, if you had linked gains at -4, -12, and -18 dB, and adjusted one gain up by
2 dB, the gains would then be set to -2, -10, and -16 dB.
To configure the gain control change mode:
1. Select the Compass > Channel Linking Preferences page.
2. Set Gain Control Linking Mode:
■
Select Linked Channel Gain changes are absolute by default, use ALT for relative
if you want linked channel controls to be set to the same value.
■
Select Linked Channel Gain changes are relative by default, use ALT for absolute
if you want linked channel controls to be changed by the same amount.
As indicated by the mode title, you can hold ‹ Alt › while dragging or clicking a control to use
the alternative mode, or use ‹ Alt+Enter › when using the keyboard to set the linked channels
using the alternative mode.

Linking Galileos
Galileos can, through Compass, share settings. When Galileos are linked, selected channels
share any changes made to their controls.
Linking Galileo Units
1. Select the Galileos page.
2. In the Link column, enable Select for the Galileos that are to share settings.
3. In the ID column, select the same link ID for each Galileo in the group.
The Galileos are now linked, and changes made to channel controls may be propagated from
one Galileo to the others.
Choosing Selected-Channel Link Mode
By default, all selected channels on all linked Galileos will share control settings. Alternatively,
you can choose to link all channels regardless of their Select status; or link only those selected
channels on the active Galileo, ignoring the Select status of channels on other Galileos. Details
of these preferences are provided below:
1. Select the Compass > Channel Linking Preferences page.
2. Set Global Galileo Select-Linking Mode:
■
Select All selected channels on selected Galileos are globally linked if you want
all selected channels on all linked Galileos to be treated as a single control. In this
mode, the linked Galileos will display a bright green bar across the top of their page
tabs. On the Galileos page, enabled Select buttons will be bright green.
■
Select Selected channels on the active Galileo tab are linked to the same channels,
by letter or number, on other selected Galileos if you want selected controls on a
linked Galileo to affect the same control on all other linked Galileos (regardless of the
selection status of that control on the other Galileos). In this mode, the linked Galileos
will display a bright blue bar across the top of their page tabs. On the Galileos page,
enabled Select buttons will be bright blue.

Select All channels on the active Galileo tab are always linked to the same
channels, by letter or number, on other selected Galileos if you want all controls
on a linked Galileo to affect the same control on all other linked Galileos (regardless
of the selection status of that control on the other Galileos). In this mode, the linked
Galileos will display a magenta bar across the top of their page tabs. On the Galileos
page, enabled Select buttons will be magenta.
Choosing Isolated Channel Link Mode Behavior
When Global Galileo Select-Linking Mode is set to All selected channels on selected
behavior of isolated channels is configurable. By default isolated channels do not participate
in the links, but you may choose to link isolated channels:
1. Select the Compass > Channel Linking Preferences page.
2. Set Global Galileo Select-Linking Mode to All selected channels on selected Galileos
are globally linked.
3. Set Isolate Mode:
■
Select Enable global linking of isolated channels if you want isolated channels to
be linked between all linked Galileos.
■
Select Disable global linking of isolated channels if you want isolated channels to
be excluded from global Galileo linking.
Atmospheric Correction and M Series Array Correction
Atmospheric Correction
Atmospheric correction applies equalization to the higher frequencies, based on environmental
conditions and the distance between the loudspeakers and the listening area, to compensate
for the attenuation of these frequencies by the air. This attenuation effect varies with temperature,
humidity, and altitude.

3. Using the Natural Environment for Atmospheric Correction controls, set the temperature,
humidity, and altitude for the facility.
You should now set the distance between the loudspeakers and listening area.
Setting Loudspeaker Distance for a Single Channel
The distance setting can be used to correct high frequency attenuation. For popular music
reinforcement or any application for which the system will be running near its limit, start with
half the actual distance between the loudspeaker or array, and the audience. If the result is too
flat or sounds unnatural, reduce the distance parameter to achieve the desired response.
1. Select the [Galileo Unit] > Output Processing > Channel Settings page.
2. If the background color of the page is dark green (light green), indicating it is part of a
selection set, de-select or isolate the channel.
3. Using the Atmospheric Correction Distance control, set the distance between the
loudspeakers and the audience.
Avoid settings of more than 40 m (130 ft) to save headroom in the very high frequencies.

CHAPTER 3: USING COMPASS TOOLS
M Series Line Array Correction
Array correction applies an EQ curve that is dependent on both the loudspeaker model and the
number of loudspeakers in the line array. As line arrays become longer they also become more
directional in the lower frequencies. Array correction controls this low- and mid-low frequency
emphasis. Up to eight unique configurations (type and size) of Meyer Sound M Series arrays
can be controlled by a single Galileo 616.
NOTE: Bypassed buttons in the Output Processing pages do not affect array correction.
Configuring M Series Array Correction
This setting assumes the output channel(s) on the Galileo 616 unit are connected to a Meyer
Sound M Series curvilinear or line array. Array Correction allows you to assign pre-configured
EQ correction to the channels to compensate for low-frequency build-up related to the length
of the array.
1. Select the [Galileo Unit] > Settings > Array Correction page.
2. Provide an identifying name for the array and change its status to Enabled.
3. From the Type selector, select one of the Meyer Sound M Series line array systems: M1D,
M2D, MILO®, M3D®, Mica, or M'elodie.
4. In the Size box, or using the rotary encoder beside it, set the number of cabinets in the
line array. An array may have up to twenty-four cabinets.
By selecting Type and Size, the appropriate equalization curve is ready for use with output
channels.
NOTE: While only a single row needs to be defined for each unique (type and size) array
configuration, it is often conceptually easier to create an entry for each line array
separately. The end result is the same, but the naming and visual separation of channels
can help illustrate important information as you continue to develop snapshots.
If all your line arrays are identical in type and size, you can define a single instance of
that array and assign all appropriate output channels to it.

Assigning M Series Array Correction to an Output Channel
To apply an M-Series array correction output:
1. Select:
■
[Galileo Unit] > Galileo Map. In the Array Corr. column, click the button that
corresponds to the channel that will be sent to the line array. The Settings > Array
Correction page will be displayed.
■
[Galileo Unit] > Settings > Array Correction.
2. For each output channel that is being sent to a line array, select its entry on the line
corresponding to the type of Array EQ it requires. Each output channel may be assigned
one array correction EQ.
Configuring MSL-4 Loudspeaker Array Correction
The Meyer Sound MSL-4 is a horn-loaded long-throw speaker that can be configured for use
in horizontal array clusters. When so configured, a low-mid frequency rise occurs. Compass
provides a TruShaping equalization setting to correct this low-frequency emphasis.
1. Select the [Galileo Unit] > Output Processing > TruShaping page.
2. Right-click TruShaping tab. Click the TruShaping EQ Load button. A file selector window
will be displayed.
3.
Navigate to the Compass/Saved Settings/Examplesdirectory and load
Set TruShaping to LD-2 Array.galileoTruShapingEq.
The TruShaping equalization curve will now be set to provide low-mid frequency correction to
the rise that is created by using the MSL-4 in a horizontal array.

Using Signal Processing
Compass provides composite equalization: you can “layer” various types of equalization, view
the summation result in a graphic plot, and adjust various EQ parameters to achieve the ideal
signal equalization curve.
There are a number of configurable settings specific to the user interface. See Input
Selecting Channels
When working with a single or dual plot display:
■
A drop-down channel selector and channel selection buttons are located above the plot.
Use either of these to select the working channel.
When working with multiple EQ plots:
■
Multiple EQ Plots (p. 54), below.
Customizing the Display
Many aspects of the plotter display can be changed, including value ranges, curves, control
handles, number of plots simultaneously displayed, metering, and more. See the Input and
setting.
1. Enable the Settings control, located in the top right corner.
2. Use the settings available in the Plotter, Handles, and Response pages to control various
aspects of the plot display.
Maximizing the EQ Plot Area
Small-screen users will benefit by maximizing the space available to the EQ plot and controls.
1. If multiple plots are displayed, enable Settings, select the Plotter page, and beside the
EQ Plots label select Single display.
53

CHAPTER 3: USING COMPASS TOOLS
2. Clear the Settings control, located in the top right corner. The various display setting
controls will now be hidden, allowing the plot more horizontal space.
3. Clear the Dual View setting.
4. Click Collapse, located to the right of the sub-page selection tabs. The control setting
controls will now be hidden, providing significantly more vertical space for the plot.
Screen-splitting the Processing Window
Large-screen users may benefit by using Dual View mode when developing EQ plots. In this
mode the entire processing control suite is duplicated in left and right halves of the Compass
window. You can use this to see two views of one channel (with access to two sets of EQ
controls simultaneously); to view a stereo pair; or to select two arbitrary channels for comparison.
1. Enable the Dual View control, located in the top right corner.
2. Use the Input Channel or Output Channel selectors to choose channels to be displayed
in either half of the Compass window.
Displaying Multiple EQ Plots
At the cost of reduced plot size, multiple plots may be displayed simultaneously:
1. Enable Settings, select the Plotter page, and beside the EQ Plots label select Multiple
display.
2. In Layout, select the size of the plot grid (w × h).
3. In Order, choose between horizontal or vertical channel numbering layout.
4. In First, select the first (top left) channel for the layout.
The channel plots will be laid out sequentially, starting at the top left and proceeding horizontally
or vertically, as selected. When necessary, the channel numbers will “wrap around” to channel
one,

Displaying EQ Plot Control Handles
Selecting an EQ control page will normally display only the control handles for that plot type.
If you wish to see other EQ handles as well:
■
Enable Settings, select the Handles page, and select the types of EQ control handle you
want displayed.
The Automatic Handles setting controls whether selecting an EQ page will display the control
handles for that plot type automatically. If this setting is cleared the plot may be viewed without
handles.
Viewing EQ Plots With/Without Composite Addition
An EQ plot may be viewed on its own, without the influence of other EQ types, or as a composite
of all EQ types.
■
Enable Settings, select the Response page, and enable/clear the EQ response components
you wish to view or hide.
Parametric EQ
Compass provides a digital version of the Meyer Sound CP-10 filter set through its five-band
(inputs) and ten-band (outputs) complementary phase parametric equalizers. As a second-order
filter, it is ideal for treating interaction artifacts.
Setting Parametric EQ Values
There are several methods available to set the value of a parametric EQ band:
■
Drag an EQ handle. Dragging a parametric EQ handle usually moves it in the gain/frequency
plane. This behavior can be changed:
■
Hold ‹ Alt › while dragging to adjust the bandwidth/gain plane.
■
Drag the plot handles to adjust specific parameters:
■
Drag the red handle to adjust frequency.
■
Drag the amber handle to adjust gain.

Drag handle crosspoints to adjust two values simultaneously.
Type values in the Freq, B/W, and Gain boxes.
■
■
“Stacking” EQ Handles for Composite EQ
You can place two or more EQ handles at the same frequency. This will result in an additive
effect, allowing you to create notch filters and other effects.
Viewing Exact Plot Values
Click and drag anywhere on the plot to view the gain response and phase response at the
frequency corresponding to the cursor location.
TruShaping EQ
The TruShaping equalizer provides four first-order filters that control shelving EQ and bandpass
EQ. With TruShaping, phase shift is kept to a minimum, making it ideal for shaping low frequency
signal and the associated subjective qualities perceived by the listening audience. When VX-1
Mode is enabled, the EQ curve will duplicate the functionality of the Meyer Sound VX-1.
Setting TruShaping EQ Values
There are several methods available to set the value for a TruShaping EQ control:
■
Drag a horizontal handle to adjust gain.
■
Drag a vertical handle to adjust frequency.
■
Drag a handle crosspoint to adjust gain and frequency simultaneously.
■
Type values in the Gain and Freq boxes.
Viewing Exact Plot Values
Click and drag anywhere on the plot to view the gain response and phase response at the

Using VX-1 Mode
In VX-1 mode the upper two gain handles are locked together, such that the upper frequency
handle has no effect on the EQ curve. This creates a smooth, broad high-frequency boost or
cut.
When VX-1 Mode is first enabled the TruShaping EQ plot does not change: this preserves your

Thirty-one bands of Graphic EQ are available on input channels. The frequency range spans
20 Hz — 20 kHz, incrementing on a logarithmic scale.
Setting Graphic EQ Values
There are two ways to set the value for a graphic EQ band:
■
Drag a slider handle to adjust frequency gain for the selected band.
■
Type a value in the Gain box.
When the Graphic EQ is active (one or more bands of EQ have a non-zero value), the Galileo

Saving and Loading Projects and Snapshots
In Compass a snapshot is a saved Galileo configuration that contains all the input, output,
summing matrix, and signal processing values for the unit. A project captures the snapshot
library and device settings. One project at a time may be loaded into a Galileo; that project may

CHAPTER 3: USING COMPASS TOOLS
contain many snapshots. Snapshots capture the state of all controls, not just those that are on
a particular Galileo unit sub-page. Recalling a snapshot instantly sets the controls and system
settings to the saved values.
At the bottom of Galileo unit sub-pages is a set of snapshot and project control buttons. These
replicate important functionality found on the Project sub-page. Except where noted, the
following instructions assume use of this set of controls.
Snapshots
Creating a Snapshot
Using the controls at the bottom of any Galileo sub-page:
1. Click Create. The Create New Snapshot window will be displayed.
2. Provide a name for the snapshot and, if
desired, a descriptive comment.
The new snapshot will be listed on the [Galileo
Unit] > Project page, in the Snapshot Library.
Recalling a Snapshot
1. Select the [Galileo Unit] > Project page.
2. From the Snapshot Library, select the desired snapshot.
3. In the Snapshot Library control set, click Recall (there are two recall buttons; the other
is in the Boot Snapshot control set.)
All control values for the Galileo unit will be changed to match those that were captured in the
snapshot.

Updating a Snapshot
Assuming a snapshot has been previously created or recalled, it may be updated to match
current control settings. Using the controls at the bottom of any Galileo sub-page:
■
Click Update.
Recalling a Boot Snapshot at Galileo Power-on
The Galileo 616 can be configured to automatically recall a specific snapshot when first
powered-on. This is very useful for defining a “safe” or default configuration.
1. Select the [Galileo Unit] > Project page.
2. From the Snapshot Library, select the desired snapshot.
3. In the Snapshot Library box, enable Is Boot.
The Boot Snapshot control will be updated with the snapshot name. The next time the Galileo
unit is powered-on, that snapshot will be automatically recalled.
Galileos that have been assigned a boot snapshot are indicated by the presence of a blue Boot
Snapshot Enabled box at the bottom center of their control pages.
Locking a Snapshot
When you have perfected a snapshot, you may want to ensure it is not accidentally modified.
1. Select the [Galileo Unit] > Project page.
2. From the Snapshot Library, select the desired snapshot.
3. In the button row below the library list, click Lock.
If the need arises, click Unlock to allow updates to the snapshot. If a snapshot with the same
name already exists, a count number will be appended to the name of the loaded snapshot’s
name.

CHAPTER 3: USING COMPASS TOOLS
Saving a Snapshot
Snapshots are usually saved as part of a Galileo project. It is also possible to save them
individually. This is especially useful as a means of copying snapshots between projects.
1. Select the [Galileo Unit] > Project page.
2. From the Snapshot Library, select the desired snapshot.
3. In the button row below the library list, click Save….
A file selection window will be displayed, through which you can select a directory and file
name for the snapshot file.
Loading a Snapshot
Individual snapshots may be loaded into the snapshot library.
1. Select the [Galileo Unit] > Project page.
2. In the button row below the library list, click Load….
A file selection window will be displayed, through which you can select a snapshot to be
loaded into the current library. Snapshot file names have the form
[file name].galileoSnapshots.
The loaded snapshots are added to the library list.
Using Snapshots in Static Facilities
A common usage scenario is found in facilities which host a variety of program material:
speeches and lectures, singing, instrumental music, and perhaps even audio-visual media
events. Each of these performance types may require a different configuration of fixed and
movable microphones, but will generally use a fixed set of loudspeakers. Churches, small
theaters, and lecture halls are representative of this application.
In this scenario you might create a project file named for the facility, and then capture snapshots

training the facility operator will be able to select and recall the appropriate snapshot for the
current activity.
Using Snapshots for Tour Setup
In a traveling show, snapshots can be used to provide a base foundation from which to quickly
develop site-specific tuning. For this purpose, you might create a separate project file for each
act, and capture snapshots of various base configurations suitable for the venues you expect
to encounter. As you tune the configuration for a specific venue, you might save new snapshots,
some of which may be useful at future sites. If you are not mixing the show, you might use
Access Control (p. 68) to lock down parts of the system.

CHAPTER 3: USING COMPASS TOOLS
Restricting Access to Compass Settings
In some venues it is advantageous to permit “public” access to some Galileo functionality while
restricting access to other controls. For instance, you may create several snapshots with control
settings that vary to accommodate speaking voice amplification, singing voice amplification,
and music amplification. It would be appropriate to allow the facility operator to select one of
the snapshots, while denying changes to the channel controls. Access lock-out settings affect
both Compass software and the Galileo front panel controls.
Locking Galileo Controls
1. Select [Galileo Unit] > Settings > Access.
2. Enable or clear the various control types. Users will have access to enabled controls only;
cleared controls will be locked against value changes by the user.
Clear All may be used to lock all controls; Set All may be used to unlock all controls.
3. In the Access Code boxes, type three one- or two-digit numbers in the range 1 — 99. The
value “zero” is reserved for removing the access code.
4. Click Change Access Code to lock-down the Galileo unit.

General Options:
Full Screen
Toggles the Compass display between a floating window which can be repositioned and
resized, and full-screen mode, which maximizes the size of the window.
This control is also duplicated in the top left corner of all windows, appearing above the
Compass tab.

User Interface Display and Control Options:
User Interface Scale
Selects a scaling factor to reduce or enlarge the size of the Compass window and window
contents. Scaling is particularly useful when running Compass on computers attached to
a low-resolution display. Display sizes and the suitable scaling factor for that resolution are
as follows:

1536 × 1152
Scaling factors greater than 100% can be useful for displays with a very fine pixel pitch,
where the 100% scale results in text that is too small to easily read.
Plotter Control Handle Scale
Selects a second scaling factor to be applied specifically to the signal processing plot
“handles,” which can otherwise become too small to be easily used at the smaller user
interface scale factors.
Value Controller Type
These options affect encoder controls:
Encoder
A “rotational” cursor movement will be used to adjust encoder values. This is a natural
movement with touch screens and is easy with a mouse; it is rather more difficult when
using a laptop touch pad.
Joystick
Moving the cursor horizontally or vertically, as if the encoder were a slider control, will
adjust encoder values. This is a natural movement with mice and touch pads; it is
somewhat unintuitive when using a touch screen.
Input Device Type
Only applicable when Value Controller Type is Joystick. These options affect the behavior
of the cursor after an encoder value is adjusted:
Mouse
When the encoder control is released, the cursor remains at the point of release. This
is normal mouse behavior.

CHAPTER 4: USER INTERFACE REFERENCE
Tablet
When the encoder control is released, the cursor returns to the encoder.
Color Mode
Selects a dark or bright user interface color set. Where colors are specified in this document,
the dark color is mentioned first (followed by the bright color).
NOTE: The file selection window is always bright. Please plan accordingly when
loading or saving files during a performance.
Typed in Decibel (dB) Values Default to Negative
When selected, gain values are assumed to be negative unless explicitly made positive by
a leading + (plus) sign.
When cleared, negative gain values must be indicated with a leading - (minus) sign.
Disable Keyboard Control of Buttons
Select to disable keyboard selection of buttons. In this mode, pressing ‹ Tab › will move the
input cursor from value box to value box, but will skip over buttons. This prevents accidental
triggering of Mute or other settings.
Clear to enable keyboard selection of buttons. In this mode, pressing ‹ Tab › will move the
input cursor to the next control, regardless of whether that control is a value box or a button.
The ‹ Spacebar › or ‹ Return › key can be used to “click” buttons.
ESC Key Removes Cursor Focus in Text Fields
When selected, pressing ‹ ESC › after entering a value for a control disables keyboard control
of the user interface. This prevents accidental changes to control values. Keyboard control
will be restored by clicking in a value box.
Select All Text When Entering Text Field
When selected, choosing a value box automatically selects the entire value. Pressing ‹ Tab ›
or ‹ Enter › sets the value; pressing ‹ ESC › will restore the original value.
When cleared, the backspace key must be used to remove the previous value.
Re-select All Text After Editing a Text Field
When selected, pressing ‹ Enter › after typing a value sets the value and then selects the
entire value, such that a new value can be typed to replace the previous value. This makes
it easy to audit a series of values in succession.

Show Meter Values
Select to display numeric value read-out to meters. Clear to have analog meters only.
Individual meters can be toggled to show or hide the meter value by using Alt+click on the
meter display.
Startup Galileo Discovery and Connection Options:
These options control the behavior of Compass when it is started:
Find available Galileos on startup
Select to search the primary network for Galileo 616 units when Compass is started,
displaying them on the Galileos tab.
When cleared, Galileos are discovered only when Find Galileos is clicked.
Relaunch and reconnect to previously connected Virtual Galileos on startup

in the same mode the next time Compass is started.
Reconnect to previously connected Galileos on startup
Remembers which Galileo units were connected, restarting them in the same mode the
next time Compass is started.
Default Delay Units
Sets the measurement unit for delay values.
Galileos that are already connected will continue to use the old measurement unit unless
Set All Galileos To Default Units is clicked. Existing delay values will be converted from
the previous measurement unit to the new unit.
Equalization Bypass on System Map is read-only

Allow Select and Isolate settings to be recalled from a snapshot
When selected, recalling a snapshot will apply the channel Select and channel Isolate values
that were captured in the snapshot.
When cleared, snapshots will recall everything except the channel Select and channel
Isolate values.
De-select all channels when the active Galileo tab changes
When selected, channel Selects are dropped when switching Galileo pages. You will need
to select channels explicitly whenever you change pages.
When cleared, channels remain selected until you explicitly de-select them.
Gain Control Linking Mode:
This setting determines how gain value differences are calculated when adjusting gains on
linked channels:
Linked Channel Gain changes are absolute by default, use ALT for relative
When a gain control is set to a new value, all linked gain controls will be set to that
value as well. If you had linked gains at -4, -12, and -18 dB, and set one gain to 0 dB,
all three gains would be set to 0 dB.
Use ‹ Alt+drag › or ‹ Alt+Enter › to adjust the linked controls by relative amounts.
Linked Channel Gain changes are relative by default, use ALT for absolute
When a gain control is changed by Δ dB, all linked gain controls will be adjusted by
Δ dB as well. If you had linked gains at -4, -12, and -18 dB, and adjusted one gain up
by 2 dB, the gains would then be set to -2, -10, and -16 dB.
Use ‹ Alt+drag › or ‹ Alt+Enter › to adjust the linked controls by absolute amounts.
Link Groups and Selects Mode:
This setting modifies the action of channel Select. See also Global Galileo Select-Linking
Mode (p. 78), below, for details regarding the interaction between this setting and Galileo
linking modes.
Selected channels are always selected in groups if part of an enabled Link Group
Enabling a channel Select for any channel in a link group enables channel Select for
all the channels in the link group.
Use ‹ Cmd+click › to override this behavior.

CHAPTER 4: USER INTERFACE REFERENCE
Enabled Link Group channels are linked independently and in addition to selected
channels
Enabling a channel Select for a channel in a link group has no effect on the channel
Select for other channels in the link group.
A dark blue (light blue) background on link group channels indicates they are individually
selectable.
Isolate Linking Behavior:
This setting determines whether isolated channels are affected by changes made to channels
to which they are linked:
Isolated channels will not be included when linking from another channel
Control changes that would normally replicate among linked channels will not affect
any isolated channels in the link group.
Isolated channels will be included when linking from another channel
Control changes made to a linked channel will affect isolated channels in the link group.
Global Galileo Select-Linking Mode:
This setting determines how control changes are propagated across a set of selected,
linked Galileo units.
Connected Galileo units listed on the Galileos page can be linked to one another by
activating their Select buttons and assigning them the same ID group. Control value
changes on one Galileo channel will then be copied to the same controls of other units.
All selected channels on selected Galileos are globally linked
Changes made to a selected channel on the active Galileo will be replicated in all
selected, non-isolated channels on the linked Galileos. If the selected channel on the
active Galileo is isolated, its changes are not propagated. Channel links on the active
Galileo do not propagate their changes.
A light green bar across the top of the Galileo tab indicates the Galileos are linked in
“all selected channels” mode. On the Galileos page, enabled Select buttons will be
bright green in color.

APPENDIX B: NETWORK INFORMATION
Compass is client-side software that connects to a Galileo 616 server and acts as a control
interface to the functions provided by the Galileo. The same functions are also available through
the front panel controls of the Galileo.
Communication between the Compass client and Galileo server takes place over standard
Ethernet network. As with other network applications, Compass requires appropriate access
to TCP/IP addresses and ports; if you have enabled a firewall or other access-restriction software
on your workstation, you may need to configure it to allow Compass to communicate with
Galileos. If you use firewall software on your workstation or network router, you will need to
open TCP/IP ports 15001 and 15002.
Compass auto-detection of connected Galileo 616 units is currently restricted to the primary
Ethernet port. If connections are made through alternate ports, connections must be configured
manually.
Virtual Galileo
Virtual Galileo substitutes a local (“running on the workstation”) Galileo 616 server in place of
a physical Galileo 616 server. This local server performs all the internal functions provided by
a real Galileo 616 (with the exception of passing audio signal).
Communication between the Compass client and Virtual Galileo server takes place over the
same standard network system as used when communicating with real Galileos. However, a
different set of TCP/IP addresses and ports are used. Your firewall should not interfere with
these communications, as they are local to the workstation.
Virtual Galileo is useful as a stand-in for real hardware during those times you need to develop
configurations without having access to Galileo hardware.

APPENDIX C: USER-DEFINED EQUALIZATION CURVES WITH
M SERIES ARRAY AND ATMOSPHERIC CORRECTION
In a typical system design, small vertical splay angles in the upper part of the array boost
long-distance coverage, while larger angles in the lower elements increase vertical coverage
for shorter distances. Those angles, along with the number of cabinets and the distance from
the array to the listening area, determine the overall response of the array. Galileo M Series
Array Correction and Atmospheric Correction create custom EQs that compensate for the
overall response of the array to help achieve a flat frequency response based on the type and
size of the array and the natural environment conditions.

You can use the Galileo to drive an array with multiple vertical zones — usually two or three
zones, depending on the design and number of elements. For designs where a flat response
is not desired (for example, user-defined equalization curves) use M Series Array Correction
and Atmospheric Correction parameters to effectively create the desired equalization curve.
The key is to apply different strategies for low and high frequencies in both the long and short
throw.
High-Frequency Equalization Strategies
For the far field, air absorption plays a critical role: the longer the distance, the greater the
attenuation of high frequencies. In this zone, high frequencies generally need correction to
compensate for energy lost over distance, and the gain needed is usually proportional to the
distance and high-frequency air absorption.
NOTE: In the near to mid-field, air absorption is not nearly as critical. Therefore, high
frequencies need less correction in this zone.

APPENDIX C
USER-DEFINED EQUALIZATION CURVES WITH M SERIES ARRAY AND
ATMOSPHERIC CORRECTION
For high frequencies, the Atmospheric Correction Distance parameter can be used to obtain
the desired correction. Start with an accurate distance value for the distance to which the
correction is needed; if the result is too flat and/or sounds unnatural, reduce the distance
parameter to achieve the desired response.
NOTE: For designs where user-defined curves or other types of response curves are
desired, always use the Atmospheric Correction Distance parameter for each channel,
NOT the Temperature, Humidity or Altitude controls.
Low-Frequency Equalization Strategies
The number of elements in an array plays a critical role for the low to mid-low frequencies. The
more elements, the more coupling and therefore the more build-up in this end of the spectrum.
Although the array can (and usually should) be zoned for implementing different equalization
curves at high frequencies, identical equalization should be maintained in all the low-frequency
filters. Different low-frequency equalization settings in the same array will degrade the coupling
effect.
For this same reason, gain tapering is not recommended for line arrays, since adjusting various
zones with an overall amplitude control for each zone results in the following:
■
Directionality decreases.
■
Low-frequency headroom decreases.
■
The length of the line array column is effectively shortened.
For low to mid-low frequencies, the Array Correction Size parameter can be used to obtain the
desired correction. Start with an accurate size value for the number of elements in the array
and then reduce it to achieve the desired response.
NOTE: Keep in mind that the M Series Array Correction section has no effect on the
Atmospheric Correction section: the two functions are independent of each other.
Changing the Array Type or Size will not change the correction produced by the Galileo’s
atmospheric functions.

Example Curves
The following curves show how changing the settings on the Galileo allows you to tailor the
response to create different contour curves. These examples use eight MILO™ high-power
curvilinear array loudspeakers in a single zone array at a distance of 60 meters, temperature of
20° C, and 50% relative humidity at sea level.
NOTE: The examples in this section are not meant to be used as a template for your
own system designs. Acoustical characteristics, physical constraints, audio content,
audience and many other factors should always be uniquely weighed into your own
applications.
Simple Flat Response Curve

is affected by two primary factors:

Depending on atmospheric conditions and distance, high frequencies may attenuate due
to air absorption.

High-frequency attenuation is corrected by setting the Natural Environment for
Atmospheric Correction to actual conditions: Temperature of 20° C, Humidity at 50%,
Altitude below 800m, and (on the channel Output Processing pages) Atmospheric
Correction Distance at 60 meters.

Low and low-mid frequency build-up is corrected by setting the M Series Array Correction
to reflect the actual type and number of loudspeakers: Array Type MILO and Array Size

USER-DEFINED EQUALIZATION CURVES WITH M SERIES ARRAY AND

At a distance setting of 60 meters — the actual distance of the array — the Galileo produces
the flattest result; any setting below 60 can be used to achieve a different response in the high
frequencies.
NOTE: For designs where user-defined curves or other types of response curves are
desired, always use the Atmospheric Correction Distance parameter for each channel,
NOT the Temperature,

An Array Size of 8 — which matches the number of elements in the array — achieves the flattest
result. However, any setting below eight can be used to achieve a different desired response
in the low to low-mid frequencies.

For designs where user-defined curves or other types of response curves are desired,
always use the Array Size parameter for each channel, NOT the Array Type selector.
