Within the Delta 1010LT’s PCI chip is a hardware digital mixer. Controlled by the Delta

Control Panel software, it may handle all of your mixdown needs, give you extra control

of all left, right and stereo levels plus pans, solos, and mutes, or simply give you an

alternate or headphone mix.

Quick Start Guide

There may not be any instant tips or tricks for understanding and using an audio interface

that is as versatile as the Delta 1010LT. However, we may be able to include some

“straight talk” to help light the way.

On the PC: Following the installation procedures for both the Delta hardware and

software will enable the 1010LT for use in Windows. The Delta 1010LT will become your

Windows sound card simply by going to My Computer | Control Panel | Multimedia, and

changing Audio settings to one of the Delta stereo pairs. In this way, the Delta card will

be the default audio device for your Windows and other media players.

On the Mac: Following the installation procedures for both the Delta hardware and

software will enable the 1010LT to be configured for use in a music program that utilizes

the ASIO drivers supplied with the Delta. Additionally, the Delta 1010LT can be used in

the Apple Sound Manager for your system sounds or in a music/recording program that

directs itself to the Sound Manager. The Delta 1010LT will become your Macintosh’s

audio device simply by going to the Apple menu | Control Panel | Sound, and changing

audio settings from “built-in” to the Delta. In this way, the Delta card will be the default

audio device for your Apple applets and a variety of media players. If you wish only to

use the Delta with an ASIO compliant music program, leave this setting on “built-in.”

You will, however, need a music/recording software application to take full advantage of

the Delta 1010LT as a production tool, and most likely that software will need to analyze

and configure the Delta 1010LT--this usually occurs when first launching the program

after the Delta 1010LT has been installed. On the PC, the 1010LT is also capable of

playing an encoded surround sound signal from the S/PDIF output using some of the

DVD player applications that exist on the market. This usually takes some audio output

configuration within the player.

The Delta Control Panel controls many of the card’s settings, and includes controls for the

digital mixer that is contained on the Delta card. While all of those settings may seem daunting

at first, it may help to know that by using only the default settings, the card is ready to playback

audio files from your computer (the control panel is set to play audio outputs from software).

This can be done from a media player or from your music application, provided the outputs

are set to a Delta output port and the software and card are properly configured.

You will be able to hear the Delta inputs under certain conditions. Using a recording

program that utilizes the ASIO or EASI drivers with the Delta 1010LT, or (in Windows)

using the Windows WDM drivers with programs that take full advantage of them, will allow

you to monitor the Delta inputs through the program, and thereby continue to use the default

settings in the Delta Control Panel (as mentioned, these are audio outputs from software).

When using the Delta card and monitoring in this fashion, there is always some degree of

latency, or delay between the the actual input signal and the monitoring of that input signal.

Another way to approach this is by directly monitoring those inputs. This can be done in

the Delta Control Panel’s “Patchbay/Router” page by selecting the Delta input and

connecting it directly to the Delta output. You can also use the Delta panel’s Monitor

Mixer to send the signal at the inputs to the Delta outputs, as well as mix those signals

with the software outputs, i.e., your music software sending audio to the Delta outputs.

This, and other recording/monitoring scenarios are covered in the Tutorials section toward

the end of the manual.

Typically a MIDI controller or MTC source would be connected to the

Delta 1010LT’s MIDI input jack. The cable is tan in color.

6. MIDI Output jack: This standard MIDI connector accepts a standard MIDI

cable. Typically a MIDI keyboard or sound module would be connected to the

MIDI output jack. The cable is black in color.

Breakout Cable 2:

7. Host Cable connector: This 44-pin female D-sub connector is used to attach

the breakout cable to the PCI host card’s male D-sub connector.

8. Analog Inputs 3-8: These jacks input analog audio from a variety of external

sources. Each jack is RCA coaxial and is compatible with RCA coaxial

(unbalanced) connections. These cables are tan in color, with the jacks colored

white for left and red for right for each stereo pair.

9. Analog Outputs 1-8: These jacks output analog audio to a variety of external

targets. Each jack is RCA coaxial and is compatible with RCA coaxial

(unbalanced) connections. These cables are black in color, with the jacks

colored white for left and red for right for each stereo pair.

10. Analog Inputs 1-2: These jacks input analog audio from a variety of external

sources. Each jack is female XLR and is compatible with two-conductor

(typically XLR or TRS) balanced connections. Inputs 1&2 can be set via

jumpers on the PCI card to accept either line level or mic level signals. These

cables are tan in color, with the jacks colored white for left and red for right.

PCI Host Adapter Card:

11. Host Cable connector 1: This 15-pin D-sub connector attaches to the supplied

breakout cable #1 to allow communication between the PCI host card and

external digital devices.

12. Host Cable connector 2: This 44-pin D-sub connector attaches to the supplied

breakout cable #2 to allow communication between the PCI host card and

external analog devices.

13. Line Level Jumper #1: This jumper set allows you to switch the XLR analog

input #1 level setting from balanced microphone level to a +4dBu line level

setting. The default setting shown is the microphone level setting.

14. Line Level Jumper #2: This jumper set allows you to switch the XLR analog

input #2 level setting from balanced microphone level to a +4dBu line level

setting. The default setting shown is the microphone level setting.

Setting the Jumpers

The Delta 1010LT’s PCI card has two sets of jumpers that can be used to control the

operating line level for the 1010LT’s analog inputs 1&2 on XLR jacks. The location of

these jumpers is illustrated in the previous section under “PCI Host Adapter Card.”

Two basic settings are possible, one for a microphone line level compatible with

low impedance dynamic microphones (those that do not require phantom power,

such as condenser mics), and the other is an operating line level of +4dBu

(typical for balanced line levels). Two variations are possible for each of these

line level settings. This is shown in the illustrations below.

The default setting when you receive your 1010LT is with the jumpers set to the

microphone line level setting. If you wish to use either or both inputs 1&2 as a +4dBu

line level input, then you will need to change the jumper setting on the 1010LT PCI card.

Changing the jumper setting is easy to do when the 1010LT PCI card is not

installed in the computer. Since it is usually impossible to change the jumpers

while the card is in the computer, it’s a good idea to make a decision now. If you

wish to connect a dynamic or ribbon microphone directly to the Delta 1010LT’s

XLR analog inputs 1&2, then leave the jumpers set to their default setting,

+4dBu. If you wish to connect the XLR analog inputs 1&2 to the output of a

balanced +4dBu device such as a pre amp or dynamics processor, you will need

to change the jumper setting.

Remember that you can change one set of jumpers and not the other, if that suits

your needs. To change the jumper:

1. Before removing the Delta 1010LT PCI host card from its protective anti-static bag,

touch the metal power supply case of the computer in order to dissipate any static

electricity your body may have accumulated. You might want to pick up a grounding

wrist strap (available from electronics stores like Radio Shack) if you want to be

doubly sure you aren't carrying a static charge that could damage the card.

2. Either hold the PCI card in your hand, or place it on an anti-static surface

(such as its protective bag). Using your fingertips or a tweezer, remove the

plastic jumper that is covering the top-most and middle metal pins. See

Illustrations 1 and 1a, below.

3. Place the jumper over the middle and bottom-most metal pins. See

Illustrations 2 and 2a, below.

Panel’s “Variable Signal Level” section of the Hardware Settings

page, then try these alternate settings.

Hardware Installation

To mechanically install the Delta 1010LT, do the following:

1. Turn off your computer and unplug the AC cord.

2. Remove the computer’s cover and position the computer so that you may

easily access its PCI slots.

3. Select the PCI slot where you will install your Delta 1010LT PCI host card.

Make sure the slot is a PCI slot. If you don't know what "PCI slot" means,

check the owner’s manual for your computer. PCI slots are distinguishable

from ISA slots by being shorter and set back farther from the outside of the

computer, however some newer computers have only PCI slots.

4. Before removing the Delta 1010LT PCI host card from its protective anti-static bag,

touch the metal power supply case of the computer in order to dissipate any static

electricity your body may have accumulated. You might want to pick up a grounding

wrist strap (available from electronics stores like Radio Shack) if you want to be

doubly sure you aren't carrying a static charge that could damage the card.

5. Remove the metal bracket that covers the access hole on the back of the

computer. This bracket is usually fastened to the computer with a single screw.

6. Position the Delta 1010LT PCI host card over the target PCI slot and fit the card

loosely over it with the card in the upright position. Press the card gently but

firmly downward into the slot until the card is completely and squarely seated

in the slot. If the card seems difficult to seat, a slight rocking motion may help.

7. Screw the Delta 1010LT PCI host card’s metal bracket down into the screw hole

on the back of your computer using the screw you removed in step 5 above.

8. Place the cover back on your computer.

IMPORTANT: Complete the attachment of your Delta 1010LT

breakout cables to the PCI card before powering up your computer.

Never attach a breakout cable to the PCI card while the computer

is on. Doing so could damage the PCI card and void the warranty.

With your computer turned off, it is now time to connect the Delta 1010LT breakout

cables to the PCI host card that you have just installed. You may at this time also want to

connect to audio gear that you using in conjunction with your Delta 1010LT.

button: select Start | Settings | Control Panel | System | Device Manager. With the Device

Manager displayed, click on the "+" next to "Sound, video and game controllers" to open

a list of devices, the Delta 1010LT being a device of that nature. Below is an example view

of the Device Manager.

This example shows the M-Audio Delta 1010LT entry in the Windows Device Manager device

list. The Delta 1010LT is properly installed with no conflicts. If you do not see your M-Audio

Delta 1010LT in your Device Manager in this fashion, please jump ahead to the

"Troubleshooting" section of this manual located on pg 56.

Verifying Delta Control Panel Software

Installation in Windows

In Windows, open the Windows Control Panel (do so via Start | Settings | Control Panel).

If your Delta 1010LT hardware and Delta Control Panel software are properly installed, the

Windows Control Panel should display an "M Audio Delta H/W" icon. By double-clicking

on that icon, you can launch the Delta Control Panel software. For convenience, you may

also create a shortcut on your desktop by dragging a copy of the "M Audio Delta H/W"

icon from the Control Panel to your Windows desktop using your mouse or trackball. After

completing the drag operation, a dialog box will ask you if you wish to create a shortcut --

click on ‘Yes.’ Once the shortcut is installed, all you have to do is double-click on the

shortcut icon on your desktop to launch the Delta Control Panel software.

NOTE: When using a music software program that is ASIO capable,

launch the Delta Control Panel software from within that program.

Some of the control panel functions will be controlled from within

that program, such as master clock setting and sample rate, so it

is desirable to launch the music program first, and then the Delta

Control Panel from the the program’s “launch” or “control panel”

button. Without the music program open however, it is okay to

open the Delta panel from your desktop or other location.

Delta Driver Software Installation on the Mac

1. Open the System folder on your Macintosh hard drive. In the System folder,

locate the Extensions folder.

2. On you Drivers CD disk, open the Mac Delta Drivers folder. Place the

extension file "Delta 1010LT Driver" in your Extensions folder by clicking on it

and dragging it to the Extensions folder.

3. If you are using a music program that uses ASIO drivers, it will also have an

ASIO folder within the application’s folder. In your Mac Delta Drivers folder

you will find three Delta 1010LT ASIO drivers. For Cubase versions 4.x, use the

"ASIO2 Delta1010LT" driver. For Metro, or earlier versions of Cubase, use the

"ASIO Delta1010LTv3" driver. For any music program that is not ASIO2 capable,

use the “ASIO Delta 1010LT” driver instead (check your program’s

documentation). Place the file "ASIO Delta" in your program's ASIO folder by

clicking on it and dragging it to the ASIO folder.

3. Drag the "DeltaPanel PPC" file onto your Macintosh hard drive. You can run the

Delta Control Panel from any place that's convenient, though music software

applications that use ASIO will allow you to launch the Delta panel from within the

program. If not, we suggest creating an alias to the control panel by highlighting it

and pressing Command (Apple key)+M. Then, drag the alias to the desktop.

4. With the Delta 1010LT PCI card installed, restarting the computer will load the

Delta 1010LT extension. You will be able to visually see the Delta extension

icon pass by as your system loads extension.

5. Go to theApple menu |Control Panel | Sound. You should see the “built-in” sound

icon, plus the Delta icon if your Delta 1010LT is properly installed. If your music

program does use ASIO, you may want to leave the Sound Manager driver set to

"built-in" for both Sound In and Sound Out. If your program does not use ASIO

(check your software’s documentation) and you will be using the Sound Manager

to communicate with your Delta 1010LT, set Sound In and Sound Out to “Delta.”

See the section “Hardware Settings Page” in the Delta 1010LT “Control Panel

Software” section for information on selecting Sound Manger inputs and outputs.

Your Delta 1010LT is now ready for audio input and output. To configure the Delta for MIDI,

you will need to have Opcode’s OMS (Open Music System) installed first. OMS is provided on

the CD that came with the unit. Opening the OMS 2.3.7 folder and double-clicking on the “Install

OMS 2.3.7” program will install OMS in your system. To install the Delta MIDI driver once

OMS is properly installed:

1. Open the “Delta Products”folder on the driver CD, then the Delta 1010LT Mac

folder. Locate the “Delta OMS Driver.”

2. On your Macintosh hard drive, in your System folder, you will find an “OMS

Folder.”Drag the Delta OMS Driver into the OMS Folder.

3. Restart your computer.

To Configure your Delta 1010LT MIDI in OMS, go to the Control Panel or Chooser under

the Apple Menu, and make sure AppleTalk is turned off (this is recommended, although

OMS will sense that it is on and prompt you to turn it off). If you are configuring OMS

for the first time, follow these instructions to configure OMS.

1. In the Opcode folder, which you will find on your hard drive, locate the OMS

Applications folder, "then OMS Setup." Double click on OMS Setup.

2. OMS will inform you that it has not yet been configured. Click OK.

3. The Create A New Studio Setup dialog box now appears. Click OK.

4. The "OMS Driver Search" box asks you to choose the port on which you've

attached the Delta MIDI (either Modem or Printer). DO NOT choose a port,

just click "Search." OMS begins Searching.

5. "OMS Driver Setup" shows the "Delta" MIDI in a list when OMS successfully

finds the driver. Click OK. OMS will now define (shows "Identifying") the

Delta output port. The "OMS MIDI Device Setup" dialog box will appear

showing the Delta's output port with a check box to the left of the port,

indicating that the port is enabled. Now click on OK.

6. Next, the "My Studio Setup" appears with a 'file save' dialog box over it. You

will now need to save your new Studio Setup before you can assign an

instrument to the Delta's MIDI output and input. Assign your instrument and

you are done. You may now exit OMS Setup by quitting the application.

Delta Control Panel Installation on the Mac

The Delta Control Panel may be placed anywhere on your hard drive, or any partition of

your hard drive that you find convenient. Once the control panel file has been dragged

from the CD onto your hard drive, you may double click it to launch the Delta Control

Panel software. You may also create an alias to the control panel by highlighting it, then

holding Apple key+M. This alias can then be placed on your desktop.

NOTE: When using a music software program that is ASIO capable,

launch the Delta Control Panel software from within that program.

Some of the control panel functions will be controlled from within

that program, such as master clock setting and sample rate, so it

is desirable to launch the music program first, and then the Delta

Control Panel from the the program’s “launch” or “control panel”

button. Without the music program open however, it is okay to

open the Delta panel from your desktop or other location.

Delta System Basics

Delta’s Analog Inputs/Outputs

The Delta 1010LT PCI Audio Card’s analog inputs and outputs are compatible with a wide

variety of audio products. The Delta Control Panel software allows you to configure the

signal level of each analog output individually, or all analog outputs as a group. Signal

level settings of +4dBu, “Consumer” (-4dBu), and “-10” are available.

+4dBu is considered a professional operating line level, and is generally associated with

balanced, two-conductor cables and connectors such as the 1010LT’s analog inputs 1 & 2.

The +4dBu setting will allow you to accept or output a “hotter” signal. The ‘Consumer’

setting is preferred for semi-pro audio equipment and some consumer equipment that can

output accept a ‘hotter’ signal than the ‘-10’ setting. The ‘Consumer’ setting offers

approximately 6dB more headroom than does the ‘-10’ setting. Semi-pro and consumer

device signal levels vary from manufacturer-to-manufacturer and even product-to-

product, so a little experimentation between Consumer and –10 settings may be required

for optimal results.

NOTE: Analog inputs 3 through 8 on the Delta 1010LT do not have

microphone pre-amplifiers built into them. Therefore direct

connection to a microphone is not recommended. Instead run the

microphone signal through a microphone pre-amp (such as the

M-Audio "Audio Buddy™" or M-Audio “DMP2™”) and then connect

the pre-amp output to the input of the Delta 1010LT.

Inputs 1 & 2 are female XLR connectors, and allow connection to balanced microphone

or line level audio signals. All other analog jacks on the Delta 1010LT breakout cable are

of the RCA (coaxial) variety. The RCA jacks allow connection to unbalanced (typically

semi-pro or consumer) connections.

The Digital Monitor Mixer

The Delta 1010LT PCI Audio Card has a hardware digital audio mixer built into its PCI

controller chip. It accepts digital audio streams from all hardware inputs and all outgoing

software audio devices, mixes them with 36-bit internal precision and then provides the

mixed output to one or more locations. For the purpose of monitoring, the output of the

mixer may be routed, via the control panel’s Patchbay/Router page, to the first set of

Delta 1010LT analog outputs (OUT1/OUT2 as a stereo pair) and/or the S/PDIF digital

output. At the same time, the mixer may be used for stereo mix-down, with the mixer’s

output recorded into the user’s application software. The digital audio mixer is configured

and controlled by the included Delta Control Panel Software.

The Patchbay / Router

In addition to the built-in monitor mixer, the Delta 1010LT PCI Audio Card includes an

output patchbay/router. The patchbay/router allows each output (analog or digital) to be

connected to a variety of input sources. The 1010LT’s outputs may accept audio from

software sources (these output devices are visible in your audio software applications) or

from hardware sources such as the analog and digital inputs or the monitor mixer. This

capability makes the Delta 1010LT quite flexible for playing and monitoring any audio

file format, or directly connecting inputs to outputs for system test purposes.

Synchronization

For proper operation, the entire Delta 1010LT system is always synchronized to a single

master clock. The master clock is chosen via the Delta Control Panel software and this

clock may be derived from the Delta 1010LT’s internal crystal oscillators, S/PDIF In, or

Word Clock In. Most of the time the master clock is taken from the internal crystal

oscillators. However, the S/PDIF and Word Clock options are used in situations where

the Delta 1010LT must be synchronized to external digital audio or sample rates derived

from an external device.

Using the initial default setting, the master clock is derived from the internal crystal

oscillators. Operation in this mode is similar to that of a generic sound card – for instance,

when an audio file is played through the Delta drivers, the software application playing

the audio file is responsible for setting the sample rate in the sound card hardware. The

Delta 1010LT supports these sample rates by using either of its internal crystal oscillators

and dividing the rate of that oscillator by some value to derive the proper sample rate.

In situations where S/PDIF In is being used, the Delta 1010LT should usually be configured

to get its master clock from the S/PDIF In data stream. The reason for this is simple – an

S/PDIF data stream coming from an external source is rarely going to be in sync with the

Delta 1010LT (or other digital audio devices in the system for that matter), even if the

sample rates are set the same. If the master clock were set to use the internal crystal, then

the incoming S/PDIF audio would have "pops," "crackles," and other undesirable audio

artifacts present in it. Instead, setting the master clock to "S/PDIF In" will synchronize the

Delta 1010LT to the S/PDIF input data and its digital audio will be transferred properly.

There is one special case to consider, however. The external unit sending the S/PDIF digital

audio to the Delta 1010LT may be "locked" to the word clock emitted from the Delta 1010,

or both the external unit and the Delta 1010LT are locked to the same external word clock.

In these cases, the Delta 1010LT and the external S/PDIF device are in-sync, and the

S/PDIF data would therefore be in-sync with the Delta 1010LT system.

We’ve discussed internal crystals and S/PDIF In as master clock sources. The third option

is Word Clock. Word Clock is the desirable choice when you want to synchronize the

Delta 1010LT with the word clock of something else in your system. That "something

else" may be a another unit that has a word clock output, or it may be a dedicated house

word clock generator.

Finally, the Word Clock and S/PDIF In options may be used to operate the Delta 1010LT

at non-standard sample rates. When one of these two options is selected, the

Delta 1010LT’s sample rate will automatically match that of the incoming word clock or

S/PDIF data stream.

NOTE: When either the S/PDIF In or Word Clock is selected

as the master clock source, the Delta 1010LT mixer’s

frequency response will be affected by whatever sample

rates you inject at the S/PDIF In or Word Clock In. This is

because (1) the digital mixer operates at the same sample

rate as the rest of the board, and (2) sample rate and

frequency response are directly correlated.

Using the Delta 1010LT with your Music

Software Application

Once the Delta 1010LT’s hardware and driver software are properly installed, it is ready for

use with your music application software. Some of these applications may require you to

highlight or enable the Delta 1010LT drivers within the program, and others may have a

utility that analyzes or profiles the audio cards in your system and enables the drivers. Your

software should have an audio device driver setup page.

WINDOWS MME AUDIO INPUT DEVICES: All Delta 1010LT analog and S/PDIF

inputs may be used simultaneously for a total of 10 input channels. Within your software

application(s), the names of the Delta 1010LT audio input devices are:

PCM In 1/2 Delta-1010LT

PCM In 3/4 Delta-1010LT

PCM In 5/6 Delta-1010LT

PCM In 7/8 Delta-1010LT

S/PDIF In Delta-1010LT

Mon. Mixer Delta-1010LT

The PCM In devices allow recording a stereo stream directly from the specified analog

input pairs. The S/PDIF In device allows you to record a stereo stream directly from the

S/PDIF input. The Mon. Mixer device allows stereo recording from the digital "monitor"

mixer built-into the Delta 1010LT. The audio data recorded from this device is the mix of

input and output streams that is set up in the Delta Control Panel software’s Monitor

Mixer page (see Delta 1010LT Control Panel Software section).

Note that all of the input devices are stereo. Your application software may break these down

further to "left" and "right" mono devices. Therefore you may see them as "Left PCM In 1/2

Delta-1010LT, Right PCM In 1/2 Delta-1010LT," "Left S/PDIF In Delta-1010LT, Right S/PDIF

In Delta-1010LT," or "Left Mon. Mixer Delta-1010LT, Right Mon. Mixer Delta-1010LT," etc.

from within your recording software.

WINDOWS MME AUDIO OUTPUT DEVICES: All Delta 1010LT analog and S/PDIF

outputs may be used simultaneously for a total of 10 output channels. Within your

software application(s), the names of the Delta 1010LT audio output devices are:

WavOut 1/2 Delta-1010LT

WavOut 3/4 Delta-1010LT

WavOut 5/6 Delta-1010LT

WavOut 7/8 Delta-1010LT

WavOut S/PDIF Delta-1010LT

All WavOut devices allow playing a stereo audio stream to the analog hardware outputs (for

WavOut 1/2, 3/4, 5/6, 7/8), the S/PDIF hardware output (for WavOut S/PDIF), and/or into the

hardware router or mixer. Your application software may break each of these stereo devices

down further to "left" and "right" mono devices. Therefore you may see them as "Left

WavOut 1/2 Delta-1010LT, Right WavOut 1/2 Delta-1010LT", or "Left WavOut S/PDIF

Delta-1010LT, Right WavOut S/PDIF Delta-1010LT", etc. from within your music software.

Other software will handle the outputs as stereo pairs, but allow you to pan audio left or right

within the pair.

Note that each device name begins with "WavOut." This is to remind you that these are

software devices, and not always connected directly to output hardware. Instead they are

connected to the Delta 1010LT’s internal patchbay/router and may be sent to one of many

destinations. For more on the patchbay/router, see the Patchbay/Router section of the

Delta Control Panel software discussion.

ASIO or EASI DRIVER INPUT DEVICES: When using the ASIO or the EASI audio

drivers with music programs that support this type of audio, the input devices are

displayed as mono devices. Within these software applications, the names of the

Delta 1010LT audio input devices are:

Analog In1 Delta-1010LT

Analog In2 Delta-1010LT

Analog In3 Delta-1010LT

Analog In4 Delta-1010LT

Analog In5 Delta-1010LT

Analog In6 Delta-1010LT

Analog In7 Delta-1010LT

Analog In8 Delta-1010LT

S/PDIF In L Delta-1010LT

S/PDIF In R Delta-1010LT

Mon. Mixer L Delta-1010LT

Mon. Mixer R Delta-1010LT

Notice the S/PDIF In and Monitor Mixer names include "L" and "R" characters. "L" indicates

the left channel of the stereo stream, while "R" indicates right channel.

ASIO or EASI DRIVER OUTPUT DEVICES: The Delta 1010LT’s ASIO and EASI

output devices appear in stereo pairs. Because each device is stereo, you may see "left"

and "right" references within your software application. This allows the application to pan

audio left and right under software control. To send a signal to a Delta ASIO output 1 (for

example) as a mono output send, one would choose "Analog 1/2 Delta-1010LT" for that

track’s output port, and then pan that output hard left. These outputs are named as follows:

Analog 1/2 Delta-1010LT

Analog 3/4 Delta-1010LT

Analog 5/6 Delta-1010LT

Analog 7/8 Delta-1010LT

S/PDIF L/R Delta-1010LT

MIDI DRIVERS: The Delta 1010LT MIDI drivers, once enabled in your software’s MIDI

Setup, will appear as a MIDI source and a MIDI port within that program’s track

configuration windows. The MIDI input driver is named "MIDI In Delta-1010LT," and the

MIDI output driver is named "MIDI Out Delta-1010LT." Some software applications allow

you to redefine/rename these devices per supplied or manually entered instrument definitions.

WINDOWS MULTIMEDIA SETTINGS: Windows may be set up to use the

Delta 1010LT as its default audio device, allowing system sounds to be sent out the

Delta 1010LT. This also enables you to use the Delta 1010LT with the sound applets

included with Windows. To set this up, go to Control Panel | Multimedia. In the Audio

Properties page, set the Playback and Recording devices to the Delta 1010LT input and

output devices of your choice.

Windows may also use the Delta 1010LT as its default MIDI device. This allows the

Delta 1010LT to be used with the MIDI applications included with Windows. To set this

up, go to Control Panel | Multimedia | MIDI. Set the Delta MIDI driver as the default

Windows MIDI driver by clicking on the "MIDI Out Delta-1010LT" entry in the driver

list, then selecting "OK" or "Apply."

MACINTOSH SOUND MANAGER INPUTS AND OUTPUTS: The Apple Sound

Manager limits the user to one stereo pair for input and one stereo pair for output. Within

your music software, the device selection when using the Sound Manager drivers for input

and output will be “Sound Manager” both for input source and for output port.

To select the Sound Manager driver, open the Apple Menu and go to Control Panel |

Sounds. For both “Sound In” and “Sound Out,” click and highlight the Delta icon, then

exit. You may select which Delta hardware stereo input pair and stereo output pair will be

used for the Sound Manager’s Sound In and Sound Out in the Delta Control Panel

“Hardware Settings Page” (see section, “Hardware Settings Page”under “Delta Control

Panel”). Whichever stereo pair you select, the software input and output device selection

within your music program will remain the same, namely, “Sound Manager.”

Delta 1010LT Control Panel Software - PC

Once the Delta 1010LT is properly installed, an "M Audio Delta H/W" icon will be

displayed in your Windows Control Panel. By double-clicking on that icon, you will

launch the Delta Control Panel software. You may also launch the Delta Control Panel

software from the desktop if you have previously created a shortcut there (see "Verifying

Delta Control Panel Software Installation" section for instructions on how to do this).

Once the Delta Control Panel software has been opened, you will see the main panel and

its several tabs. To display a desired page, click on its tab. Below are functional

descriptions of each page.

NOTE: When using a music software program that is ASIO capable,

launch the Delta Control Panel software from within that program.

There will be a button in the ASIO or Audio setup page that will

allow you to do so. Some of the control panel functions will be

controlled from within that program, such as master clock setting

and sample rate, so it is desirable to launch the music program

first, and then the Delta Control Panel from the the program’s

“launch” or “control panel” button. Without the music program

open however, it is okay to open the Delta panel from your desktop

or other location.

Monitor Mixer Page

The Monitor Mixer is the first page that appears when the Delta Control Panel is opened,

and controls the digital mixer built into the Delta 1010LT’s PCI controller chip. As

described in previous sections, the output of this mixer may be assigned to the

OUT1/OUT2 analog outputs and/or the S/PDIF Out digital output (this selection is made

in the Patchbay Router page). At the same time, the mixer outputs may be recorded in

stereo by software.

The Monitor Mixer Page is essentially a collection of volume level faders, audio level (or

‘peak’) meters, and solo/mute controls. For each mixer output and input channel there is

one of each: a volume fader, a peak meter, a solo control, and a mute control.

LEVEL FADERS: Each volume fader may be controlled by dragging the fader ‘handle’

vertically with the mouse, or by clicking on the ‘handle’ to make it active and then

adjusting it with the up/down cursor keys of your computer keyboard. Because the mixer

has no gain, these faders only attenuate (reduce) the signal levels. The highest setting is

0dB, or ‘Unity Gain.’ The default fader setting is the quietest setting, –144dB, which

essentially mutes the audio. A pair of level faders may be "ganged" so that both channels

may be adjusted together as a stereo pair.

Also, at the top of each fader and meter is a fader level "fine adjustment" control. Clicking

on the small "up" and "down" arrows will adjust the corresponding fader setting in 0.5dB

increments. Next to each fine adjustment control is a numerical fader readout that is always

current and active.

PEAK METERS: Each peak meter indicates an audio signal level in "dB relative to

full-scale." This means that a full-scale signal is referred to as "0 dB" and a signal that is

12dB "quieter" than full-scale is referred to as "-12dB." The meters are vertically

color-coded into three sections: green, yellow and red. The green section represents a safe

zone, ranging from approximately -48dB to -12dB. Most audio signals should

appropriately fill this section of the meter. The yellow section ranges from -12dB to -3dB

as the signal approaches a ‘hotter’ level. For best capture resolution, recording in this area

is both safe and advised. The red section of the meter ranges from -3dB to 0dB. On the

input level meters, a 0dB condition indicates overload and audio clipping may occur.

Therefore be careful to adjust the incoming audio levels so that they do not peak in the red

section too long (you might use the monitoring capability of the Delta 1010LT to let your

ears be the judge). On all output level meters, 0dB indicates full-scale output. Unlike the

inputs, clipping is impossible on the outputs because of the 36-bit resolution built into the

mixer hardware.

MASTER VOLUME: At the left side of the Monitor Mixer page, you will see the ‘Master

Volume’ faders and peak meters. These faders have the longest ‘throw’ and highest meter

resolution of any level controls in the mixer page. They control the overall stereo level of

the mixer output. The peak meters indicate the output signal levels with respect to full-scale

and are directly affected by the settings of the master volume faders.

MIXER INPUTS: The ‘Mixer Inputs’ are inputs to the monitor mixer. These inputs accept

hardware audio streams (directly from the Delta’s analog and digital input ports) and

software audio streams (digital audio generated in software to be output). This combination

of streams makes the monitor mixer extremely flexible. Each mixer input channel has its

own level fader and may be panned anywhere in the left/right stereo field. Each input also

has its own peak meter. The peak meters indicate the incoming "pre-fader" levels of the

incoming audio and are therefore not affected by the fader settings. However, the input

faders do affect the levels of the signals exiting the mixer and you will see the affect of the

input faders on the output "Master Volume" peak meters.

Because of the large number of mixer inputs, not all inputs are displayed simultaneously.

You may use the scroll bar at the bottom of the Delta Control Panel to scroll the view left

or right. On the PC, from far left to right the inputs are labeled "WavOut 1/2” through

“WavOut 7/8," then "WavOut S/PDIF." These inputs accept the digital audio streams being

sent from your software application (or Windows) to the driver devices with those same

names. Each name begins with "WavOut" to remind you that these are software streams

and may not necessarily be routed to any physical outputs (see Patchbay/Router Page).

Further to the right are more channels, labeled "H/W In S/PDIF" and "H/W In 1/2 through

7/8." These mixer inputs are audio streams from the physical Delta 1010LT hardware

inputs, hence the "H/W" at the front of each label.

PAN: Each mixer input may be individually panned anywhere in the stereo output mix. A

pan control is positioned directly under each input channel peak meter and has the

appearance of a small vertical pointer. To make a coarse adjustment, click on the pan control

with your mouse and drag it to the desired position. For finer adjustment (in 1% increments),

you may click on the pan control to make it active, and then use the left/right or up/down

cursor keys on your computer keyboard. Either way, while the pan setting is being adjusted,

its value will appear numerically in the Master Volume’s status box (below the Master

Volume Stereo Gang control) as a percentage from left pan to right pan: -100% represents

far left, +100% represents far right, and 0% represents the center.

SOLO: Each mixer input channel has a "Solo" checkbox associated with it. Clicking on and

activating a Solo box will solo the selected channel by essentially muting all other signals.

When more than one channel has Solo selected, all solo channels will be summed to the

solo ‘buss’(path), which is what one might consider an ‘in place’ solo as opposed to a PFL,

or pre-fader listen (levels and pans still apply). Deactivating all solo boxes will return all

input channels to their previous mute/unmute states.

MUTE: Every mixer input channel has a "Mute" checkbox associated with it. Clicking on

and activating the Mute box will remove that signal from the stereo buss. Deactivating the

Mute box will add the signal back into the stereo buss.

STEREO GANG: All input channel pairs have a "Stereo Gang" capability. Clicking on and

activating the Stereo Gang checkbox will link (or "gang") the left/right faders so that both

channels may be adjusted together as a stereo pair.

Patchbay/Router Page

The Patchbay/Router page allows you to connect each of the Delta 1010LT’s hardware

outputs (4 pairs of analog outputs and 1 pair of digital output channels) to specific audio

sources within the Delta 1010LT board. To display this page, click the "Patchbay/Router"

tab of the Delta Control Panel.

The leftmost vertical column of Patchbay/Router page, "H/W Out 1/2," connects this

analog stereo pair to one of eight stereo sources:

1. The default setting, "WavOut 1/2," connects ports OUT1 and OUT2 to your

music software or Windows multimedia applet. In other words, when music

software plays audio to the device named "WavOut 1/2 Delta-1010LT" it will

be routed directly to the "hardware" analog outputs 1 & 2 of your 1010LT

breakout cable.

2. The second option, "Monitor Mixer," connects ports OUT1 and OUT2 to the

outputs of the Delta 1010LT monitor mixer. For more information of the

capabilities of the monitor mixer, please see the section "Monitor Mixer Page."

3. The third option, "S/PDIF In," connects ports OUT1 and OUT2 directly to

the hardware S/PDIF input on the Delta 1010LT PCI host card. The left

channel of the S/PDIF In is routed to OUT1 and the right channel of the

S/PDIF In is routed to OUT2.

4. The fourth option, "S/PDIF In (L/R Rev.)," functions identically to the third

option, except that the left and right channels are swapped. Therefore in

this mode, the left channel of the S/PDIF In is routed to OUT2 and the right

channel of the S/PDIF In is routed to OUT1.

5. Selections five through eight connect the hardware analog inputs 1 & 2, 3 &

4, 5 & 6, or 7 & 8 (respectively) directly to the 1010LT’s hardware analog

outputs 1 & 2. For example, if "H/W In 1/2" were selected, any signal

present at the IN1 port will be copied to OUT1, and any signal present at the

IN2 port will be copied to OUT2. This same behavior applies to "H/W In

3/4," "H/W In 5/6," and "H/W In 7/8" when selected.

The next three vertical columns of the Patchbay/Router page (from left to right), "H/W

Out 3/4," "H/W Out 5/6," and "H/W Out 7/8," connect these hardware analog outputs to

one of four sources. Since the three columns function identically, we’ll use "H/W Out 3/4"

as the example:

1. The default setting, "WavOut 3/4," connects ports OUT3 and OUT4 to your

music software or Windows multimedia applet. In other words, when music

software plays audio to the device named "WavOut 3/4 Delta-1010LT" it will

be routed directly to the "hardware" analog outputs 3 & 4 of your 1010LT

breakout cable.

2. The second option, "S/PDIF In," connects ports OUT3 and OUT4 directly to

the hardware S/PDIF input on the Delta 1010LT PCI host card. The left

channel of the S/PDIF In is routed to OUT3 and the right channel of the

S/PDIF In is routed to OUT4.

3. The third option, "S/PDIF In (L/R Rev.)," functions identically to the second

option, except that the left and right channels are swapped. Therefore in this

mode, the left channel of the S/PDIF In is routed to OUT4 and the right

channel of the S/PDIF In is routed to OUT3.

4. Options four through seven connect the hardware analog inputs 1 & 2, 3 & 4, 5 &

6, or 7 & 8 (respectively) directly to the 1010LT’s hardware analog outputs 3 & 4.

For example, if "H/W In 1/2" were selected, any signal present at the IN1 port

will be copied to OUT3, and any signal present at the IN2 port will be copied to

OUT4. This same behavior applies to "H/W In 3/4," "H/W In 5/6," and "H/W

In 7/8" when selected.

The rightmost vertical column of Patchbay/Router page, "H/W Out S/PDIF," connects the

Delta 1010LT’s hardware S/PDIF outputs to one of eight sources:

1. The default setting, "WavOut S/PDIF," connects the S/PDIF Out port to your

music software or Windows multimedia applet. In other words, when music

software plays audio to the device named "WavOut S/PDIF Delta-1010LT" it

will be routed directly to the hardware S/PDIF output on your Delta 1010LT

PCI host card.

2. The second option, "Monitor Mixer," connects the S/PDIF Out port to the

outputs of the Delta 1010LT monitor mixer. For more information on the

capabilities of the monitor mixer, please see the section "Monitor Mixer Page."

3. The third option, "S/PDIF In," connects the S/PDIF Out port directly to the

hardware S/PDIF input on the Delta 1010LT PCI host card. The left channel

of the S/PDIF In is routed to the left channel of S/PDIF Out and the right

channel of the S/PDIF In is routed to the right channel of S/PDIF Out.

4. The fourth option, "S/PDIF In (L/R Rev.)," functions identically to the third

option, except that the left and right channels are swapped. Therefore in this

mode, the left channel of the S/PDIF In is routed to the right channel of

S/PDIF Out and the right channel of the S/PDIF In is routed to the left

channel of S/PDIF Out.

5. Selections five through eight connect the hardware analog inputs 1 & 2, 3 & 4,

5 & 6, or 7 & 8 (respectively) directly to the 1010LT’s S/PDIF Out port. For

example, if "H/W In 1/2" were selected, any signal present at the IN1 port will

be sent to the left channel of the S/PDIF Out, and any signal present at the IN2

port will be sent to the right channel of the S/PDIF Out. This same behavior

applies to "H/W In 3/4," "H/W In 5/6," and "H/W In 7/8" when selected.

At this point, you may begin to realize the versatility of the Monitor Mixer and the

Patchbay/Router, and the relationship between the two. You may want to re-read this section

and make some practice adjustments within the Delta Control Panel software to become

proficient in routing and mixing, as well as check out the Tutorials section toward the end of

this manual. If somewhere in the process you become confused, you may always restore the

default settings to use the card as a straight 10-in 10-out device -- just choose the topmost

option in each of the Patchbay/Router columns.

Hardware Settings Page

The Hardware Settings page of the Delta Control Panel gives you control over

miscellaneous features of the Delta 1010LT. To display this page, click the "Hardware

Settings" tab of the Delta Control Panel.

MASTER CLOCK: This section allows you to select the source of the board’s master

clock: Internal Xtal (crystal), S/PDIF In, or Word Clock. Master clock operation is

outlined in the Synchronization section of this manual. Internal Xtal is the default setting.

Be sure to select "S/PDIF In" if you will be recording or monitoring an S/PDIF stream, or

"Word Clock" if you wish to synchronize your digital audio with a source device that is

Word Clock capable.

NOTE: If "S/PDIF In" is selected as the master clock source, be

sure to supply a valid S/PDIF signal to the board’s active S/PDIF

input. Otherwise, erratic timing and/or improper sample rates will

be experienced. The same is true for selecting "Word Clock" as the

master clock setting – make sure there is a valid word clock signal

present at the Delta 1010’s Word Clock In.

Once a master clock source has been selected, its synchronization status is continually

monitored and displayed below the master clock radio buttons. If internal crystal is selected,

the status display will always say "Locked." On the other hand, if S/PDIF In or Word Clock

is selected as the master clock source, the control panel will display "Locked" only when a

valid S/PDIF or Word Clock signal is detected. It will display "Unlocked" when there is no

signal at the selected input, or when the signal is corrupt or invalid for any reason.

CODEC SAMPLE RATE: This section indicates the present board sample rate, as set by

application software. The sample rate selected here will be used to drive the digital mixer

and all outputs. The "Rate Locked" checkbox is used to force a sample rate upon the

system. It is disabled by default to allow software access to all supported sample rates.

When checked, it causes the driver to only operate at the selected sample rate. This means

that any application that attempts to open the Delta 1010LT driver at a sample rate other

than the one selected here will fail to do so and will post an error message. "Reset Rate

When Idle" is selected when you want the sample rate to return to a particular setting

when a software application is not actively using the board. This is particularly handy for

keeping the digital mixer running at a specific sample rate.

NOTE: Because the digital monitor mixer runs at the sample rate of

the rest of the board, and because sample rate directly affects

frequency response, it may be desirable to keep the sample rate at

or above 44.1 kHz while using the monitor mixer. This is

accomplished by enabling "Reset Rate When Idle" and selecting a

sample rate of 44.1 kHz or greater.

S/PDIF SAMPLE RATE: When using S/PDIF In as your master clock, this section tells the

driver what the expected S/PDIF input sample rate is. The section is only displayed when the

board is set to use S/PDIF In as the master clock source. From the list, select the sample rate

closest to that of the S/PDIF input data. The sample rate selected here will be the only sample

rate available to the software applications. Therefore, you must set your audio software

application to this same sample rate or else the application will display an error message.

NOTE: When S/PDIF In is the master clock source, the digital

monitor mixer will run at the sample rate received at the S/PDIF In.

Since frequency response and sample rate are directly related, the

mixer frequency response will be directly related to the sample rate

of the S/PDIF input data.

WORD CLOCK SAMPLE RATE: When using Word Clock In as your master clock, this

section tells the driver what the expected word clock input sample rate is. The section is

only displayed when the board is set to use Word Clock In as the master clock source.

From the list, select the sample rate closest to that of the incoming word clock. The sample

rate selected here will be the only sample rate available to the software applications.

Therefore, you must set your audio software application to this same sample rate or else

the application will display an error message.

NOTE: When Word Clock is the master clock source, the digital

monitor mixer will run at the sample rate received at the Word

Clock in. Since frequency response and sample rate are directly

related, the mixer frequency response will be directly related to the

sample rate of the S/PDIF input data.

MULTITRACK DRIVER DEVICES: The Delta 1010LT drivers intelligently synchronize the

beginning of recording and playback across all audio devices on the board. When using

application software that is capable of using multiple channels simultaneously, select "Single and

In-Sync" to ensure that all audio channels will begin playback and/or recording at the same time.

Otherwise select "Independent" to allow the audio channels to play independently – this setting

may be desirable if more than one application needs to access the Delta 1010LT simultaneously.

The selection “Multi-card Sync” will remain grayed out until a second Delta PCI card (of which

there are a variety) is installed in the system. When you wish to synchronize two (or more, up

to four) Delta cards, select Multi-card Sync on the second and successive cards. Then, select

S/PDIF as your master clock, and connect the S/PDIF output of the first card to the S/PDIF input

of the second card, etc. This ensures that when the application goes into record or playback, it

waits until all audio ports are open before it commences with recording or playback of audio.

DMA BUFFER SIZES: This section specifies the amount of system memory dedicated to

digital audio buffering. Setting a buffer size that is too small may result in clicks or pops

in the audio stream as some data may be lost. Larger buffers cause slightly more latency

but prevent the pops and clicks that might occur with smaller buffer sizes – the default

settings are recommended but you may desire to tweak these default settings to suit your

tastes. This buffer size must be set in the Delta Control Panel before you launch your

music software. When using ASIO with the Delta 1010LT, set the buffer size in the control

panel, then exit the control panel. After doing so, launch your music software.

VARIABLE SIGNAL LEVELS: This section has two layers, providing extremely

versatile control of your Delta 1010LT’s input and output operating line levels.

In the first layer there are three selections available for globally setting the operating line

levels for the Delta 1010LT’s analog input and output ports. These selections are labeled

“+4dBu,” “Consumer” (-4dB), and “-10dBV,” represented by sets of radio buttons each for

both the Delta analog inputs and the Delta analog outputs. These sections are labeled “All

Inputs” and “All Outputs,” respectively.

The default setting is “Consumer” for both the input and output levels. Consumer is a

good “middle of the road” setting, and will work well in many situations. The setting you

choose ultimately should match the line level of the source audio device (for the inputs),

and the target audio device (for the outputs). Check the user’s guide for these external

devices for information on their input and/or output line levels.

At the Delta analog outputs, a +4dBu setting will give the “hottest” output signal level.

Generally, this signal level is associated with balanced audio inputs. The Delta 1010LT’s

outputs are unbalanced, but can still interface successfully with balanced inputs. The

Consumer and -10dBV settings are typically associated with unbalanced operation for both

consumer and prosumer audio gear, with Consumer being less hot (-4dBV) and -10dBV

being the least hot. As a rule of thumb, if your signal levels in the computer are sufficient

but your target device is not receiving enough level, try a hotter output signal level setting.

At the Delta analog outputs, a +4dBu setting will give the most headroom for recording,

allowing the Delta 1010LT to accept a hotter signal level. If your source audio device puts

out less signal, such as unbalanced consumer and prosumer equipment, then the lower

settings of Consumer and -10dBV will lower the headroom, bringing record ceiling closer

to the signal that you are recording. As a rule of thumb, the lower the signal level of your

source audio, the lower the input signal level should be set.

A unique case here are the Delta 1010LT’s inputs 1&2. While all of the other inputs and

all of the outputs are unbalanced on RCA connectors (single conductor with a shield),

inputs 1&2 will accept balanced cables on XLR jacks (two conductor with a shield). You

may want to set these inputs to a +4dBu signal level setting while setting the rest of the

inputs to a different line level setting.

Eight faders are also available for setting each input and output level either individually

or in stereo pairs. This should be considered an advanced settings page, useful when the

source audio or target devices are diverse and need custom configuration. To access this

second layer, click the button labeled “Sliders” located in the lower left-hand corner of the

Variable Signal Levels section of the Hardware Settings page.

Initially, the location of the faders will reflect the last radio button selection made in the

first layer. After a change has been made in the second layer, the first layer will show no

radio button selection, indicating that a custom setting has been made. The screenshot

below shows this second layer with the first two faders adjusted to a line level of +4dBu

for the two balanced inputs on XLR jacks.

You will notice that the “Input” radio button is selected here, giving us a set of eight faders

that control input levels. Click the “Output” radio button to access the output faders. Also,

you can click the “Mono” button to control each fader individually, or the “Stereo” button

to control faders in stereo pairs.

At any time, the individual faders may be set to vary the input and output levels of a

particular port or ports. You can use the +4dBu, Consumer, and -10dBV buttons as a

starting point, or operate independently of them. The faders can be set incrementally in

.5dB steps, of which there are 18. If working in surround sound, these faders can be used

to calibrate speakers for monitoring purposes. If using the 1010LT inputs or outputs for

other purposes, the faders allow you to address multiple sources and targets individually.

S/PDIF Page

The S/PDIF page of the Delta Control Panel configures the S/PDIF output format and

displays the status of the S/PDIF input. To display this page, click the "S/PDIF" tab of the

Delta Control Panel software.

DIGITAL INPUT: This group box displays the current S/PDIF input status. The

Delta 1010LT’s S/PDIF receiver is capable of recognizing a valid input signal versus an

invalid, corrupt or non-present one. When a valid signal is detected at S/PDIF In, this

group box displays "Valid Input Detected." When an invalid signal is detected or no signal

is present, the group box displays "Invalid or Not Present." Below this message are two

‘grayed-out’ buttons: "Coax(RCA)" and "Optical." These are functions of the Delta DiO

2496, another product in the M-Audio Delta line, one with both optical and coaxial

S/PDIF inputs. These controls do not apply to the Delta 1010LT.

DIGITALOUTPUT FORMAT: Within the "Digital Output Format" group, you choose the digital audio

format of the S/PDIF output. The default setting, "Consumer," is a true S/PDIF format and is recognized

by all consumer devices. The alternate "Professional" setting is an AES/EBU type data stream, but

electrically S/PDIF. This is a work-around that is recognized by some but not all AES/EBU devices.

For both consumer and professional output formats, the "Advanced" checkbox will allow you

to force a few particular status bits in the outgoing S/PDIF signal. The advanced option is for

expert users only; however, if you decide to go exploring, change a few bit settings and get

lost, you can always select the "Restore Defaults" button to restore the outgoing status bits to

their factory settings. When "Consumer" and "Advanced" are both selected, the group

"Consumer Format Advanced Settings" will appear. When "Professional" and "Advanced" are

both selected, the group "Professional Format Advanced Settings" will appear. These groups

are described below:

CONSUMER FORMAT ADVANCED SETTINGS (Copy Mode): Copy protection, also

known as Serial Copy Management System (SCMS), is written into the S/PDIF subcode, a

reserved part of the S/PDIF digital stream that is independent of the actual audio data being

transmitted. It can be used to inhibit the amount of copies that can be made, or allow for

unlimited copying. Three SCMS modes are available. "Original (Copy Permitted)" indicates

that the source material may be copied by a receiving device. "1st Generation" indicates that

the source material is a first generation copy. Most devices that are capable of recording will

reject material with this SCMS mode set. The final option is "No SCMS" which may be used

to override the other two modes and allow a recording device to successfully record the audio

data. Different manufacturers’ products may interpret these codes differently and require you

to set these bits by "trial-and-error" until proper operation is achieved.

CONSUMER FORMATADVANCED SETTINGS (Emphasis): This status bit is used to indicate

if pre-emphasis has been applied to the outgoing digital audio signal. The default is "None" and

rarely will any user want to set the value to "50/15uSec" unless the transmitted audio has been

encoded with 50/15uSec pre-emphasis.

PROFESSIONAL FORMATADVANCED SETTINGS (Data Type): The user may assign the

outgoing data as audio or non-audio data. Many devices ignore this setting. The obvious

default is "audio," however, choosing “non-audio” is appropriate if you wish to send an AC3

signal (Dolby Digital 5.1 surround sound) out of the S/PDIF output. Some software DVD

players are capable of this, as well as AC3 or Dolby Digital encoding software.

PROFESSIONAL FORMAT ADVANCED SETTINGS (Emphasis): The user may choose to

indicate or not indicate if pre-emphasis has been applied to the outgoing digital audio signal.

The default is "None" and rarely will any user want to set the value to "CCITT" or "50/15uSec"

unless the transmitted audio has been encoded with one of those types of pre-emphasis.

Save, Delete, Load Buttons; H/W Installed

At the rightmost side of the Delta Control Panel are the Save, Load and Delete buttons as

well as an "installed hardware" set of radio buttons. These controls appear regardless of

what Delta Control Panel page is being displayed.

SAVE, DELETE, LOAD: The Delta Control Panel always retains the last settings entered.

However the Save, Delete, and Load functions expand this capability to store different

sets of control panel settings using different configuration file names. These

configurations are then available for recall at a later date and time.

Clicking the ‘Save’ button brings up a dialog box prompting you to name the current

configuration. Once you have done this, click ‘OK’, and your current configuration has been

saved to disk. If you decide that you no longer need a particular configuration, click the

‘Delete’button. Highlight the name of the configuration file that you wish to delete, and click

the ‘OK’ button. To recall or reload a saved configuration, click the ‘Load’ button. Highlight

the name of the configuration file that you wish to recall, and click ‘OK’. Those settings will

now appear in the Delta Control Panel and the driver will automatically update the hardware.

H/W INSTALLED: Up to four Delta cards may be installed in a system at one time. This

section displays all installed Delta cards, and allows you to select which particular card is

under the control of the control panel software. To select a card for configuration, click

the radio button to the left of that particular card in the “H/W Installed” list.

Delta 1010LT Control Panel Software - Mac

The Delta Control Panel must be placed on the hard drive by dragging the application from

the Drivers CD. Once this is done, an alias may be created by highlighting the Delta

Control Panel on the hard drive and pressing the Apple key+M. Then, this alias may be

dragged to the desktop. Double clicking either will launch the control panel. Once the Delta

Control Panel software has been opened, you will see the main panel and its several tabs.
