CHAPTER 1: INTRODUCTION
GALILEO™ PRODUCT OVERVIEW
The Galileo loudspeaker management system is a complete hardware and software solution
with all the necessary tools for driving and aligning sound reinforcement systems with multiple
zones. The system consists of:
■
Galileo 616: A fully digital matrix processor with six inputs and 16 outputs.
Designed as the perfect complement to Meyer Sound’s self-powered loudspeakers,
Galileo includes array correction for M Series array products, presets for Meyer Sound
systems of various sizes and types, and digital implementations of technologies used in
Meyer Sound’s groundbreaking analog processors and line drivers. The system includes a
wide selection of bandpass and parametric EQs, delay and gain adjustments, air absorp-
tion compensation, and other signal processing.
Galileo’s Composite EQ architecture offers the most extensive equalization of any current
loudspeaker management system. By providing both CP-10 complementary phase para-
metric equalization and TruShaping™ low-order shaping equalization, Composite EQ pro-
vides the right tools for addressing both acoustic anomalies and subjective sonic
requirements. The Galileo 616 features full digital operation with fixed latency across all
output channels regardless of the processing applied (see Table 1). All internal processing
is performed at 96 kHz with a 32-bit floating point vector processor.

*Test conditions were factory default settings: All input and output EQ and TruShaping™ filters enabled but
set to flat response, no other filtering enabled.
For maximum flexibility, the Galileo 616 can be controlled from its front panel, using its
navigation buttons and LCD screen, or from the Compass control software.

GALILEO 616 USER GUIDE
■
Compass™ control software: 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 sys-
tem. 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 enter-
ing values numerically for greater precision.
SIM® 3 Support
The Galileo 616 can be directly connected to the SIM® 3 audio analyzer, providing complete
audio measurement capabilities for complex audio systems.

CHAPTER 2: GALILEO 616 FEATURES AND FUNCTIONS
GALILEO 616 PROJECTS
A Galileo 616 project is the organizational structure in which one or more snapshots — full
configurations for all parameters and system settings — are kept. The Galileo 616 holds only
one project file at a time and allows the user to scroll through and load any snapshots con-
tained in the project.
The Compass control software, running on a computer, does not have its own memory for
system settings and parameters, and just reads what it is connected to. So when Compass is
connected to a Galileo 616, it reads and displays the project file and the current active snap-
shot that is contained in the unit’s memory. However, loading another project file (stored on
the computer) into the Compass control software when it is connected to a Galileo 616
replaces whatever project file is currently in the Galileo 616.
CAUTION: Opening a project file in the Compass control software when the
computer is connected to a Galileo 616 will overwrite the project, and its snap-
!
shots, residing in the Galileo 616 (if the Overwrite option is selected when opening the
project). To merge snapshots from another project file into the current project in a
Galileo 616, use the Merge Project option on the Open Project dialog box (click More
for this option to appear).
TIP: You can use the Compass control software to read and save the
Galileo 616’s project file (and the snapshots it contains) as a backup procedure.
This file can be saved in the computer (or to a network server, CD, or other storage
medium) and later reloaded via Compass to the Galileo.

GALILEO 616 USER GUIDE
INPUT CONNECTORS (FROM CONSOLE)
Galileo 616 Input Connectors
Analog Inputs
Connections from analog sources, including analog mixing consoles, will be made via the six
XLR-3F connectors labeled A through F on the left side of the rear panel. The six analog inputs
are electronically balanced, and feed state-of-the-art A/D converters operating at 24-bit reso-
lution at a 96 kHz sample rate. Within the System Settings window of the Compass control
software, the Input Channel Types will be set to Analog (the default setting). These connectors
will accept signal levels up to +26 dBu at the default setting, and can also be set to +20 dBu.
NOTE: 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. Thus the actual
improvement attained depends on the quality of the grounding between components.
For this reason the default setting has been changed to +26 dBu. In either setting, the
digital gain will compensate for either analog output gain so that the overall system
output level set in the Galileo will remain the same.
21
CHAPTER 3: CONNECTING THE GALILEO 616
AES/EBU Inputs
Digital inputs following the AES/EBU standard may be directly connected to the Galileo 616,
using the top three XLR-3F connectors outlined in blue and labeled A, C, and E on the left side
of the rear panel. Standard stereo AES/EBU digital audio signals at sample rates up to 96 kHz
are accepted. The meters are monitoring the digital signal, so the levels being displayed are
the same with digital and analog input.
NOTE: Within the System Settings window of the Compass control software or
the Galileo 616 front panel, the Input Channel Types will be set to AES via the
drop-down menu. Since the AES/EBU signal carries two channels of digital audio, the
second connector in the selected pair is covered with a red X, and is disabled.
Compass System Settings, Input Channel Types
Both analog and digital input sources can be used simultaneously with Galileo 616. For exam-
ple, AES/EBU signals can feed inputs A and C (inputs B and D are disabled), and analog sig-
nals can feed inputs E and F.
22
GALILEO 616 USER GUIDE
OUTPUT CONNECTORS (TO LOUDSPEAKERS/ARRAYS)
Galileo 616 Output Connectors
The Galileo 616 provides 16 outputs on XLR-3M connectors, featuring high-resolution 96 kHz,
24-bit D/A converters. These outputs have the same line-driving capabilities as Meyer
Sound’s analog line drivers, providing signal levels up to +26 dBu. The Galileo 616 can easily
drive Meyer Sound self-powered loudspeakers to full output at all frequencies, even over long
lines.
23
CHAPTER 3: CONNECTING THE GALILEO 616
CONNECTING THE SIM-3022 ANALYZER
Galileo 616 SIM 3 Connectors
The rear panel of the Galileo 616 includes a connector for direct connection to the SIM-3022
Audio Analyzer. Once connected, the Galileo 616 can act as a line switcher for the analyzer.
SIM 3 users can measure across any selection of inputs and outputs without any additional
patching beyond the single cable connection to the analyzer.
The default bus address for the Galileo is 10, and the available range is 10 through 14 so that
multiple Galileo units may be connected and measured. When the analyzer is connected, it
will be auto-detected by Galileo, and its presence will be noted in the SIM 3 Settings section
of the System Settings window in the Compass control software, and by the SIM 3 LED on the
Galileo front panel.
NOTE: Within SIM 3, addresses 0 through 9 are reserved for the SIM-3088 line switcher
units.
24
GALILEO 616 USER GUIDE
Looping SIM Connector
A second SIM-type connector is included on the rear panel of the Galileo 616. It may be used
to connect an additional Galileo unit or a SIM-3088 line-level switcher.
NOTE: If a SIM-3088 switcher is connected to the looping connector of a
Galileo, a SIM-3004 remote power supply will also be required; make sure that
the power supply connector marked “Connect to 3022 Analyzer Only” is used for this
connection.
NOTE: SIM 3 integration requires Galileo Firmware 1.7.0 or higher.
System Settings for Galileo with SIM 3 v1.7.0
The settings in SIM 3 software release v1.7.0 or later allow two probe points when using the
SIM 3 bus extension cable between Galileo and the SIM 3 analyzer. Galileo has additional
parameters that can be set in System Settings > SIM 3 Settings. The Console setting is fixed
as Post Matrix. The Processor has two probe points: Output Post Delay and Output Post
Gain. Output Post Delay includes parametric and TruShaping EQ, SIM 3 Trim, Polarity and
Delay. Output Post Gain includes everything in Output Post Delay plus Atmospheric Correc-
tion, Array Correction, and High/Low Pass and Gain.
Before you can measure a Galileo using SIM 3, you will need to verify your switcher configura-
tion within the SIM 3 software. From the SIM 3 software, go to Branch Setup > Switchers;
addresses 10–14 are reserved for Galileo. Next simply connect the bus cable between the two
devices using the Line Switcher port on the back of SIM 3. There are three branch combina-
tions available when measuring the Galileo.
Combination 1
■
Console = Galileo Output Post Matrix (ex. Ad 10, Ch 1 Sw 10, Cons 1). This uses the out-
put of the Galileo Summing Matrix as the signal that feeds the Console bus.
■
Processor = Galileo Output Post Processing (ex. Ad 10, Ch 1 Sw 10 Proc 1). This uses the
output of the Galileo Output Processing as the signal that feeds the Processor bus.
NOTE: Selecting Cons 1 on the Console channel will automatically select Proc 1
on the Processor channel. The transfer function shown will represent the output
processing applied using Galileo.
25
CHAPTER 3: CONNECTING THE GALILEO 616
Combination 2
■
Console = Front Panel Signal Generator (ex. Ad FP Ch 0 Generator). The SIM signal gener-
ator is used as the signal that feeds the Console bus.
■
Processor = Galileo Output Post Processing (ex. Ad 10, Ch 1 Sw 10 Proc 1). This uses the
output of the Galileo Output Processing as the signal that feeds the Processor bus.
NOTE: The transfer function shown will include any input and output processing
applied using Galileo and/or the mixing console.
Combination 3
■
Console = Front Panel Line Input 1 (ex. Ad FP 1 Line In 1) This uses the signal received at
Line Input 1 which can be in parallel to the console output feeding Galileo.
■
Processor = Galileo Output Post Processing (ex. Ad 10, Ch 1 Sw 10 Proc 1). This uses the
output of the Galileo Output Processing as the signal that feeds the Processor buss.
NOTE: The transfer function shown will include any input and output processing
applied using Galileo and/or the mixing console.

■
SIM 3 Bus Address: Select from 10 through 14 by rotating the Blue knob clockwise to go
up in value, and counterclockwise to go down in value.
SIM 3 Trim: Select from Disabled or Enabled by clicking or rotating the Blue knob.
SIM 3 Trim allows the SIM operator to directly see the extent of their gain changes. In the
SIM3 interface, Room response shows acoustic relative gain, Processor shows electronic rel-
ative gain, and Result shows a combination of both.
A post processor trim or gain stage is helpful for crossover gain setting. Crossover gain set-
ting is achieved by viewing a memory trace of one loudspeaker and setting a second to match
it at the crossover frequency. The gain of the second loudspeaker is adjusted until the traces
match. If the gain is set in the Processor then the Room response will show a different cross-
over frequency than the Result. If the gain stage is post processor, both Room and Result
agree on the frequency. For frequency based crossover, the post processor SIM 3 Trim is pre-
ferred. For relative levels between subsystems, the in processor gain stage is preferred.
NOTE: The acoustical crossover is defined as the point of equal level of two sys-
tems. If a mid-hi loudspeaker and a subwoofer are measured individually, the
crossover might appear at 200 Hz. This would be the same reading in both Room and
Result, because the processor is at unity in both. This indicates that the subwoofer must
be turned down for the crossover to be 100 Hz. If you attenuate the subwoofer in the
processor loop, the crossover will move down in the Result but will not change in the
Room response. The subwoofer will still appear to need to be turned down since the
change happened outside of the Room response. If the change is made in the output
post processor SIM 3 Trim, the crossover will drop to 100 Hz in both Room and Result.
Once the SIM 3 settings are configured, return to System Settings by pressing Cancel, or
press Menu to return to the Galileo Map.

Access Settings
Press the Enter button or the Blue or Green knob from System Settings to select this function.
Access Settings allows Galileo’s front panel to be locked from further changes with an access
code, and allows the system engineer to specify which parameters may be changed and
which ones will remain inaccessible to another user (or to accidental button pushing).
The access list is identical to that in the Compass control software, and includes the ability to
modify Projects and recall Snapshots, change gains, polarity, delays, and equalization, mute
channels, link groups, and update the Galileo firmware. Use the Up and Down arrows to scroll
through the parameters. Use the Enter button or press or turn the Blue knob to allow or deny
access to particular parameters, by selecting Yes or No for each.
The default Access Code is “0 0 0”, which allows unrestricted access to all parameters; it is
shown at the top of the Access Settings page. To change the code, highlight Lock Access
Settings and press the Enter button or the Blue knob.
A screen called Enter New appears, with instructions. Use the three knobs to scroll through
numerals 0 through 99 to create three sets of one- or two-digit numbers, which the person
setting the code must remember; press the Enter button to accept the code. The Access Set-
tings page reappears, with the Access Code blank and Unlock Access Settings appearing in
the list of options.
To unlock the device, highlight this option and press the Enter button or the Blue knob, use
the three knobs to set the correct code, and press the Enter button. The Access Code will
appear at the top of the page and parameters may now be changed.
When a parameter such as input gain or parametric equalization is locked, and an attempt is
made to change it, a screen saying “This setting is locked” appears. Press the Cancel button
to remove this screen and go back to the previous page.
32
GALILEO 616 USER GUIDE
CAUTION: Be certain to remember the access code that has been used to lock
the Galileo front panel parameters from any changes. It must be entered cor-
!
rectly or changes will not be able to be made — and it will be necessary to contact
Meyer Sound Technical Services to obtain help with unlocking the unit.
Network Settings
Network Settings Page
Press the Enter button or the Blue or Green knob from System Settings to select this function.
Network Settings provides fields for device Nickname and for IP Type. Additional relevant
fields are offered for DHCP (dynamic) and Static IP addresses. Toggle between them with a
push of the Blue knob or the Enter button. The DHCP mode supports direct cable connection
between the computer’s Ethernet card and the Galileo 616. The DHCP will also reveal the
MAC address. This will display below the assigned IP address.
With either DHCP or Static IP, highlighting “Write Network Settings” and pressing Enter or the
Blue knob will load the settings and open a note saying “Writing Configuration”. “Reload Net-
work Settings” will load the IP address of the current server, and opens a note saying “Read-
ing Configuration” before writing those values into the provided fields. Static IP has fields for
IP Address, Net Mask, and Gateway, as well as Write Network Settings and Reload Network
Settings.
A utility is offered that allows an IP Address, Net Mask, and Gateway number to be created by
highlighting each of the four value positions, scrolling the Blue knob to the desired value, then
using the Right arrow to go to the next value position. For each of these fields, press Menu to
accept the changes, or Cancel to ignore the changes.

CHAPTER 4: USING THE GALILEO FRONT PANEL
Input Range and Output Range
Input Voltage Range Page
Select Input Range or Output Range from the System Settings page to set the voltage range
at either +20 dBu or +26 dBu. Apply the settings globally by highlighting “Set All Voltage
Ranges to +20 dBu” (or +26 dBu) and pressing the Enter button.
Adjust the individual input or output voltage range for each channel by scrolling to the desired
channel using the Up and Down arrows, and then pressing or turning the Blue knob to toggle
between the two values.
NOTE: 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. Thus 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 so that the overall system output level set in
Galileo will remain the same.

SUMMING MATRIX
Summing Matrix, 8 + 8 Configuration
Press the Enter button or the Blue knob from the Galileo Map page to enter the Summing
Matrix. A selected (active) audio route is designated by a circle at any crosspoint within the
matrix; a blank signifies no audio routing between an input and an output. The box-shaped
cursor will outline any crosspoint on which it is placed. The input letter and output number
corresponding to the current cursor position are highlighted, and the Select LEDs on the
inputs and outputs will also light.
Navigate the Summing Matrix by using the Left and Right arrows (or the Blue knob) to scroll
through outputs, and the Up and Down arrows (or the Green knob) to scroll through inputs.
To select (or deselect) an audio route between an input and an output, press the Enter button.
This will toggle the crosspoint between unity gain (0.0 dB, shown with an O) and fully attenu-
ated (–90 dB or –Inf, shown with a blank).
35
CHAPTER 4: USING THE GALILEO FRONT PANEL
Change the gain at the crosspoint where the cursor is presently located by turning the Red
knob — clockwise for gain and counterclockwise for attenuation. The range is from +20 dB to
–90 dB, and is designated in the matrix as a [ – ] for levels below unity gain, and a [ + ] for lev-
els above unity. The actual level is shown for the cursor position in “gain = xx dB” in the upper
left corner of the Summing Matrix window, and is also shown in a highlighted box on the
screen while the value is being changed via the Red knob.
Summing Matrix, Attenuation
CAUTION: Placing the cursor on a crosspoint containing a value other than unity
gain or off (one with a [ – ] or [ + ] in it) and then pressing the Enter button will first
!
turn it off and then a second press will change the value to unity gain.
NOTE: When in the Summing Matrix, pressing the Enter button is similar to the
Router Mode in the Compass control software. The crosspoint where the cursor
is located will toggle between on (unity gain) and off (minus infinity).

USING TRUSHAPING EQ
TruShaping EQ with EQ Point
When TruShaping EQ is selected in the Input or Output Processing pages, one EQ point is
presented at a time on the page. These points are nominally centered at 125 Hz, 500 Hz, and
4 kHz, though once their frequency has been changed for one channel using the Blue knob,
the new value replaces these values for that Galileo project.
TruShaping EQ with Equalization Changes
Press the Left and Right arrows or press or turn the Green knob to select among the TruShap-
ing EQ points. The selected band and upper or lower EQ point will flash, and any frequency
and gain changes made will affect that point and band. The bands are:
■
Low Shelving: Left-most part of frequency line and dot are flashing; the Blue knob moves
frequency and Red knob changes gain.
57
CHAPTER 4: USING THE GALILEO FRONT PANEL
■
■
■
■
■
Low Bandpass, lower frequency: Left-most dot and section of frequency line just above
it are flashing; allows the lower frequency of this filter to be changed with the Blue knob,
and the Red knob changes gain.
Low Bandpass, upper frequency: Central dot and section of the frequency line to its left
are flashing; allows the upper frequency of this filter to be changed with the Blue knob, and
the Red knob changes gain.
High Bandpass, lower frequency: Central dot and section of the frequency line to its right
are flashing; allows the lower frequency of this filter to be changed with the Blue knob, and
the Red knob changes gain.
High Bandpass, upper frequency: Right-most dot and section of the frequency line to its
left are flashing; allows the upper frequency of this filter to be changed with the Blue knob,
and the Red knob changes gain.
High Shelving: Right-most dot and section of the frequency line are flashing; the Blue
knob moves frequency and Red knob changes gain.
NOTE: For the TruShaping EQ settings, turn the Blue knob to adjust the exact
“knee” frequency for the upper and lower points for each EQ band, and then turn
the Red knob to adjust the amount of boost or cut. In the upper right corner of the
page, a fixed field says “gain [1 — 4] = X.X dB”. The field named “gain1” is Low Shelv-
ing, “gain2” is Low Bandpass, “gain3” is High Bandpass, and “gain4” is High Shelving.
TIP: When a channel is on its TruShaping EQ page in either the graph or numeric
view, pushing the Enter button will toggle between Enabled and Bypassed.
NOTE: Three “knee” points are available with the TruShaping filter; the upper fre-
quency boundary of one filter is also the lower boundary of the one above it.

USING PARAMETRIC EQ
Parametric EQ with EQ Points
When Parametric EQ is selected in the Input or Output Processing pages, all available EQ
points are presented on the page — five for inputs and 10 for outputs. Choose the particular
parametric EQ point to change using the Left and Right arrows; the selected one will blink.
Once a Parametric EQ point is selected, use the knobs to adjust the parameters, as follows;
the knobs behave the same as a single band of the Meyer Sound analog CP-10 parametric
equalizer:

■
Blue Knob: Moves the frequency center for each point; the value is shown in the “f=X.X”
field on the top left.
■
Green Knob: Adjusts the bandwidth of the parametric EQ point; turn clockwise to narrow
and counterclockwise to widen between 0.10 and 2.00; the value is shown in the
“bw=X.XX” field on the top center.
59
CHAPTER 4: USING THE GALILEO FRONT PANEL
■
Red Knob: Adjusts the boost and cut of the parametric EQ point; clockwise for gain and
counterclockwise for attenuation; the value is shown in the “g=X.XdB” field on the top
right.
NOTE: Press and hold the knobs to make coarser adjustments (wider frequency
intervals, bandwidth by 0.1, gain by 1 dB), and just turn the knob for finer adjust-
ments.
TIP: By pushing any channel select button, input or output, the display goes to
the Processing page for that channel. When in one of the Edit windows (Paramet-
ric or TruShaping, High/Low Pass for Outputs), the screen goes directly to the Edit win-
dow and EQ display for that channel.
NOTE: To bypass the parametric EQ section in a channel when in the graph or
numeric page, press Menu+Enter.
GALILEO EQ GRAPH ZOOM MODES
Cursor Zoom
Cursor zoom places a cursor on the EQ page and allows the expansion of the curve in both
the horizontal and vertical scales, from +/–18 dB to +/–1 dB, and from 20 Hz to 20 kHz to
increments of only a few Hz in the LF to a few hundred Hz in the HF. Select Mode > Cursor
when in an EQ graph (Input or Output Processing, in Parametric or TruShaping or Low/High
Pass) by pressing the Up arrow, highlighting Mode, pressing the Down arrow to open the sub-
menu, using the Up and Down arrows to highlight Cursor, and pressing the Enter button.
Turning the Blue knob will scroll through the EQ curve and the values at the cursor point will
be shown at the top of the screen. Pushing the Blue knob and turning clockwise will zoom the
curve horizontally. Turning the Red knob will scroll the EQ curve vertically in either direction
from the default centered position, and pushing it while turning will zoom the vertical scale.
Turning the Green knob will simultaneously zoom the horizontal and vertical scales, while
pressing it will reset the graph to the default view.
