About the Delta 1010
Digital Recording System
3
Delta 1010 is a professional audio interface with a total of 10 inputs and 10
outputs. The interface features eight 1/4” balanced/unbalanced analog inputs
and outputs as well as a pair of coaxial (RCA) S/PDIF I/O. Delta 1010 can create
pristine 24-bit recordings at sampling rates of up to 96 kHz.
Connect line-level audio sources (i.e., keyboards, mixers, preamplifiers, etc.) to the 1/4”
input jacks on the rear of the interface. Set the operating line level for each input using
the +4/-10 switch located next to each jack. Connect your DAT recorder, MiniDisc
player, or other digital device to Delta 1010’s S/PDIF ports on the PCI Host card.
Control all routing and hardware settings using the Control Panel software.
The sturdy 1U rack-mount chassis houses all of the A/D and D/A converters, keeping
them away from the electrically noisy environment inside your computer and assuring
the best audio performance. The rack unit features Word Clock I/O connectors, which
allow you to synchronize Delta 1010 with all of your other Word Clock capable devices.
Also, the interface features MIDI input and output ports, allowing you to connect MIDI-
capable devices (synthesizers, drum machines, etc.) to your computer or to synchronize
external devices with your interface using a sync protocol such as MIDI Time Code
(MTC).
Finally, the Delta 1010 PCI Host Adapter card features a flexible digital mixer. This
mixer handles routing within the interface and gives you control over volume, pan, solo,
and mute just like on a hardware mixer used for monitoring.

IMPORTANT: Do not connect the PCI Host Adapter card to the rack-mount
chassis when your computer is powered on. Doing so may damage the
interface. Only connect (or disconnect) the PCI card and rack-mount unit when
your computer is powered off.
IMPORTANT: The Host Cable connector features a 25-pin jack that looks
like the parallel (printer) port connection found on some computers. If your
computer has a parallel port, be careful not to confuse these two connectors
and do not attempt to connect the PCI Host Adapter card to anything other than
the rack-mount portion of the Delta 1010 interface. Doing so may damage the
interface.
The PCI Host Adapter card and rack-mount portion of the
interface are connected using a standard 25-pin “D-Sub” cable.
This is the same type of “bidirectional printer cable” used to
connect printers to the parallel port (printer port) of a computer.
This type of cable is commonly available through computer and
professional audio stores and M-Audio has successfully tested
Delta 1010 with cables up to 25 feet in length. If the supplied
Host Cable is not long enough for optimal for computer/
interface placement, consider replacing the included cable with
a longer one.

Delta System Overview
7
Analog Inputs/Outputs
Delta 1010’s analog inputs and outputs allow you to record a variety of audio sources
and to playback your recordings to many destinations. On the rear of the interface, you
will find eight 1/4” inputs and eight 1⁄4” outputs with independent +4/-10 signal level
buttons (11) next to each jack. Be sure to set these switches properly to ensure the
best possible sound quality.
All of the analog inputs and outputs on the rear of the Delta 1010 are balanced 1/4”
jacks. These jacks allow connection to either balanced (TRS) or unbalanced (TS) line-
level devices.
NOTE: Since Delta 1010 does not have microphone pre-amplifiers built into the
inputs, it is not possible to use a microphone that is connected directly to the
interface. To record a microphone, you must first pass the microphone signal
through a microphone preamplifier (such as the M-Audio TAMPA) and connect
the preamplified line-level or S/PDIF output to the input of the Delta 1010.
The Digital Monitor Mixer
Delta 1010 features a hardware digital audio mixer built into its PCI Host Adapter card.
This mixer accepts digital audio from all hardware inputs and all software audio outputs,
mixes them with 36-bit internal precision, and then provides the mixed signal to analog
outputs 1-2 and/or the S/PDIF outputs for monitoring purposes. While the mixer is
primarily intended to be used for creating monitor mixes, it may also be used for stereo
mixing since its output can be recorded back into your audio application. The digital
audio mixer is configured and controlled by the included Control Panel software.

|
11Delta 1010 User Guide
The Patchbay / Router
In addition to the built-in Monitor Mixer, Delta 1010 also provides virtual signal patching
and routing capabilities. This “Patchbay/Router” is accessed through the Control Panel
software and allows a variety of sources (including your music software, the analog
and digital inputs of the interface, or the Monitor Mixer output) to be linked to various
physical outputs on the interface. This flexible routing capability allows you to use Delta
1010 in a variety of different situations and to quickly reconfigure the interface without
having to physically disconnect and reconnect the hardware inputs and outputs on the
rear of the interface.
Synchronization
For proper operation, all digitally interconnected audio systems (including the Delta
1010 interface) must be synchronized to a single master clock. If your digital audio
systems are not configured in this way, you are likely to hear clicks, pops, and other
glitches in your audio streams. The Control Panel software allows you to synchronize
the interface to its internal clock or to “lock” to an external clock source being received
at the S/PDIF or Word Clock inputs. This allows you to easily install the Delta 1010
hardware into any kind of digital environment where S/PDIF or Word Clock are being
used.

Delta 1010 User Guide12

Using Delta 1010 with your Audio Software
8
After Delta 1010’s hardware and drivers have been installed, you may need to
select or enable the interface in your audio software before you can begin
recording. This process is usually done through a “setup” or “audio preferences” menu
within the program. Refer to your software’s documentation to learn how to do this.
Audio Inputs:
Once your audio software is configured, you may begin recording with the interface.
The following list should help you associate the input names displayed by your audio
software with Delta 1010’s corresponding physical inputs:
Display Name Corresponding Inputs
Delta 1010 1/2 Analog Inputs 1/2
Delta 1010 3/4 Analog Inputs 3/4
Delta 1010 5/6 Analog Inputs 5/6
Delta 1010 7/8 Analog Inputs 7/8
Delta 1010 9/10 S/PDIF Input
*Delta 1010 11/12 *Summed Monitor Mixer Signal
NOTE: There may be slight variations in the naming of inputs when using
certain audio applications. For example, an input pair may be labeled “ASIO
1-2” instead of “Delta 1010 1/2.” Furthermore, some programs may break down
the inputs listed above into individual “left” and “right” mono channels. In this
case, the software may display the inputs as “Left Delta 1010 1,” “Right Delta
1010 2,” etc. Refer to your application’s user guide to learn more about how
inputs are labeled.
“Delta 1010 1/2” through “Delta 1010 7/8” correspond to analog inputs 1-8 on the rear
of the rack-mount interface.
“Delta 1010 9/10” corresponds to the red S/PDIF input on the PCI Host Adapter card.
NOTE: The S/PDIF Input will not accept incoming signals if Delta 1010’s Clock
Source is set to “Internal Xtal” in the Control Panel. To ensure proper operation,
set the Clock Source to S/PDIF and make sure that the connected source
device is configured as clock master. Please see the Digital Synchronization
and Multi-Device Setup Guide found at http://www.m-audio.com for more
information.
*“Delta 1010 11/12” is the output of the hardware Monitor Mixer on the PCI card and
can be selected if you wish to record the combined physical and virtual inputs (audio
returning from your recording software) of the Monitor Mixer.

Audio Outputs:
The following list should help you associate the output names displayed by your
software with Delta 1010’s corresponding physical outputs:
Display Name Corresponding Outputs
Delta 1010 1/2 Analog Outputs 1/2
Delta 1010 3/4 Analog Outputs 3/4
Delta 1010 5/6 Analog Outputs 5/6
Delta 1010 7/8 Analog Outputs 7/8
Delta 1010 9/10 S/PDIF Output
NOTE: There may be slight variations in the naming of outputs when using
certain audio applications. For example, an output pair may be labeled “ASIO
1-2” instead of “Delta 1010 1/2.” Furthermore, some programs may break down
the outputs listed above into individual “left” and “right” mono channels. In this
case, the software may display the outputs as “Left Delta 1010 1,” “Right Delta
1010 2,” etc. Refer to your application’s user guide to learn more about how
outputs are labeled.
When using the Patchbay/Router’s default settings, signals from your audio application
will be sent directly to Delta 1010’s corresponding physical outputs. Keep in mind that
the Patchbay/Router allows you to modify the output routing of the interface. In other
words, if the Patchbay/Router default settings have been altered, selecting an output
port by name in your audio software may not send audio to the corresponding hardware
output. To learn more about the Patchbay/Router, see the “Patchbay/Router Tab”
section in the Control Panel chapter of this guide.
NOTE: Some audio applications may make certain Control Panel settings
unavailable while the application is open. If your software does this, close the
audio application before changing your Control Panel setting. Alternatively,
certain DAW applications allow you to launch the Control Panel or change
Control Panel settings from within the application itself. This process varies
from program to program, but it is usually done through the “configuration” or
“audio setup” page of your software.

Control Panel Software
9
Delta 1010 is a powerful audio interface with a variety of options and parameters
relating to its operation. After installing the Delta 1010 drivers, you can use the
Control Panel software to configure the various parameters of the interface. Since the
appearance and functionality of the Control Panel varies slightly between Windows XP
and Mac OS X, each operating system is covered separately in this guide.
Delta Control Panel for Windows XP
This section covers the Control Panel for Windows XP users. Mac OS X users should
skip to the following section of this User Guide to learn about the Mac OS X Control
Panel.
To access the Delta Control Panel in Windows, double-click the M-Audio icon in the
system tray, or click Start > Control Panel and double-click the Delta 1010 Control
Panel icon. Your audio software may also allow you to access the Control Panel from
within the application itself.
Monitor Mixer Tab
In order to hear your Monitor Mix, you first need to route the Monitor Mixer’s output
signal to Delta 1010’s analog outputs 1/2 or to its S/PDIF output. This is done by
selecting “Monitor Mixer” from the H/W Out 1/2 or H/W Out S/PDIF column in the
Patchbay/Router tab.

|
15Delta 1010 User Guide
Monitor Mixer is the first tab that appears when the Control Panel is opened. This tab
controls the digital mixer built into the Delta 1010 PCI Host Adapter card and has the
following controls and indicators:
< LEVEL FADERS: Each volume fader is controlled by dragging the vertical
slider with your mouse, or by clicking on the small up and down arrows above
the faders (these “fine adjustment” arrows will raise or lower fader in 0.5dB
increments). The current fader setting is displayed numerically above each fader.
Note that the Monitor Mixer has no gain and that its faders only attenuate
(reduce) incoming signal levels once the signals have been converted to digital
audio. The highest setting is 0dB (or ‘Unity Gain’) and allows signals to pass
through unaffected. The default fader setting (-144dB) is the quietest setting and
will essentially mute the channel.
NOTE: To make precise edits to a level or pan slider, click a slider to select
it and use the arrow keys on your computer keyboard to move the selected
slider.
< VU METERS: Each channel features a VU meter that indicates audio levels in
“dB relative to full-scale.” This means that the loudest possible signal is referred
to as “0dB” and a signal that is, for example, 12dB lower than the maximum
loudness is referred to as “-12dB.”
The meters are color-coded into three sections: green, yellow and red. The green
section represents the “safe” zone and ranges from approximately -48dB to -
12dB. The yellow section ranges from -12dB to -3dB, and the red section ranges
from -3dB to 0dB. Once a signal reaches (or exceeds) 0dB, it means the signal
is overloading Delta 1010’s analog-to-digital or digital-to-analog converters and
is “clipping” or distorting. Unlike the analog distortion found on guitar amplifiers
and effects pedals, digital distortion is harsh, unmusical, and should generally be
avoided.
Therefore, we recommend setting input and output levels so that the loudest
peaks of your incoming signal will reach the top of the yellow range but will
generally not enter into the red zone. Technically, your signal may enter into
the red zone without resulting in distortion but this not generally recommended
since it leaves very little headroom. In other words, one loud note during a
performance or mix may result in a severely distorted recording or mix.
< MASTER VOLUME: The Master Volume section is found to the left of the Mixer
Input section. These faders control the overall output level of the Monitor Mixer.
The adjacent VU meters indicate the Monitor Mixer’s output levels and are “post-
fader.” This means changes to the master fader will affect the levels displayed on
the VU meters.

Delta 1010 User Guide16
|
< MIXER INPUTS: The Mixer Input channels are found to the right of the Master
Volume section. These channels receive audio directly from Delta 1010’s analog
and digital inputs as well as from the outputs of your audio software. This allows
you to mix your incoming signals with your previously recorded tracks to create
a hardware monitor mix that is virtually free of the delay (or “latency”) that is
inherent in all software-based digital mixing systems.
NOTE: The VU meters in the Mixer Input section are “pre-fader.” This means
that the meters display the incoming signal before the signal passes through
the faders. Since the VU meters are pre-fader, making adjustments to a fader
will have no impact on the levels displayed on its corresponding meter. The
input meters have been set up in this way so that you will always see the
“true” incoming signal levels. This helps you set optimum output levels on
devices that are connected to Delta 1010, regardless of how the faders may
be set up in the Monitor Mixer.
Because of the large number of mixer inputs, not all inputs are displayed
simultaneously. The scroll bar at the bottom of the Mixer Input section allows you
to scroll through the various inputs.
The inputs are labeled (from left to right): “WavOut 1/2” through “WavOut
7/8,” then “WavOut S/PDIF.” These inputs accept the digital audio streams
being sent from your audio application to the driver devices with those same
names. These names begin 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 “H/W In 7/8.” These mixer inputs are audio streams from the
physical Delta 1010 hardware inputs.
< PAN: Each mixer input may be individually panned from left to right using the
horizontal slider beneath the channel’s volume fader.
< SOLO: Each mixer input channel features a “Solo” checkbox. When a channel’s
Solo box is checked, all other channels will be temporarily muted and only the
“soloed” channel will be heard. Deactivating all solo boxes will return all input
channels to their previous mute/unmute states.
Note that it is possible to solo more than one channel at a time on the Monitor
Mixer. If more than one channel is soloed, all solo channels will be heard while
all channels that are not soloed will be muted. To return to normal operation,
uncheck all Solo boxes.

|
17Delta 1010 User Guide
< MUTE: Every Monitor Mixer channel has a “Mute” checkbox. When this box
is checked, its associated channel will not be routed to the stereo output and
will not be heard in the monitor mix. When the box is unchecked, its associated
channel will be routed to the mixer’s output.
< STEREO LINK: All of the Monitor Mixer’s channel pairs have a “Stereo Link”
checkbox. When this box is checked, the left/right faders move together so that
the channels may be adjusted as a stereo pair. When this box is unchecked, the
faders can be adjusted independently.
Patchbay/Router Tab
Each column in the Patchbay/Router tab represents a physical output pair on your
Delta 1010 interface. The radio buttons in each column allow you to select the audio
source for that physical ouput.
To use the Patchbay/Router, first locate the Delta 1010 output that you’d like to
use—the outputs are listed across the top of the tab. H/W Out 1/2, 3/4, 5/6, and 7/8
correspond to analog outputs 1-8 while H/W Out S/PDIF corresponds to the S/PDIF
output.
Next, click the radio button for the input source you’d like to connect to your chosen
output. The available options listed in the column below each output. Delta 1010 will
now route that audio source to your selected output.
The input sources are described below:
< WavOut 1/2 through 7/8: These inputs correspond to the outputs of your audio
software.
< Monitor Mixer: This input corresponds to the output of the Delta 1010 Monitor
Mixer. This audio source can only be routed to analog outputs 1-2 and/or the
S/PDIF output.

< S/PDIF In: This input corresponds to the S/PDIF input.
< S/PDIF In (L/R Rev.): This corresponds to the S/PDIF input but swaps the left
and right channels.
< H/W In 1/2 through 7/8: These inputs correspond to the hardware analog
inputs of the Delta 1010 interface.
TIP: To restore the Router/Patchbay to its default settings, select the topmost radio
button in each column.
Hardware Settings Tab
The Hardware Settings tab gives you control over a variety of features of Delta 1010.
These features are grouped into the following sections:
NOTE: Some audio applications may make certain Control Panel settings
unavailable while the application is open. In this case, you will need to adjust these
settings through the audio application itself. This process varies from program to
program, but it is usually done through the application’s “Configuration” or “Audio
Settings” menu. Refer to your audio software’s documentation to learn how to do
this.
< MASTER CLOCK: This section allows you to select the source of the interface’s
master clock. Delta 1010 allows you to select among the following three
sources: Internal Xtal, S/PDIF In, and Word Clock.
If you are using your Delta 1010 by itself, this parameter must be set to “Internal
Xtal” for the interface to work properly. This setting uses Delta 1010’s internal
crystal oscillator as the source of the master clock.
If you have connected a S/PDIF device to your Delta 1010’s S/PDIF input, set
S/PDIF as the source of Delta 1010’s master clock and make sure that the
external S/PDIF device is configured to provide the master clock signal. This will
slave Delta 1010 to the external device’s clock and allow S/PDIF signals to enter
the interface.

If you have connected a Word Clock device to your Delta 1010 and would like
to use that device’s clock as the master clock source, select Word Clock as the
source of Delta 1010’s master clock. This will slave Delta 1010 to the external
word clock device’s clock.
NOTE: It is possible to synchronize Delta 1010 through its Word Clock input
while simultaneously receiving signals at the S/PDIF input. However, all
connected digital input devices need to be synchronized to the same clock
source before the digital signals enter the Delta 1010 interface.
The box below the radio buttons indicates whether Delta 1010 is clocking to a
valid internal or external clock. It states “Locked” when the interface is locked to
a clock and “Unlocked” when Delta 1010 is not receiving a valid clock signal.
For more information about Clocking, please see Appendix A: Clocking at the
end of this guide and/or read the Digital Synchronization and Multi-Device Setup
Guide found on http://www.m-audio.com..
< CODEC SAMPLE RATE: This section lets you select the sampling rate of the
interface and determine the rate at which all of the digital components of Delta
1010 (A/D and D/A converters, Monitor Mixer, etc.) will operate. This section
also includes the following checkboxes:
• Rate Locked: The “Rate Locked” checkbox allows you to force Delta 1010 to
operate at the chosen sample rate. This will prohibit audio applications from
attempting to operate Delta 1010 at a sample rate other than the one selected
in the Control Panel.
By default, this box is left unchecked and allows your audio software to choose
any sample rate that is supported by the Delta 1010 hardware.
• Reset Rate When Idle: Check this box if you would like Delta 1010 to default
to the chosen sample rate when the interface is not actively being used by your
audio application.
NOTE: The Reset Rate When Idle box is provided as a convenience for
users who wish to play all sounds (such as Windows system sounds
(typically 22kHz), the output of your computer’s CD player (44.1kHz)
or DVD player software (typically 48kHz), etc.) through the Delta 1010
hardware. However, please be advised that doing so may cause the clock
rate to be changed, and this may result in a sample rate mismatch between
running audio applications. As a general rule of thumb, we recommend
users to turn off all system sounds and to only use Delta 1010 with their
audio software if possible. This will prevent possible issues related to
undesired pitch or speed changes of digital audio.
NOTE: Certain sample rate options are “grayed out” because Delta 1010
does not support these rates.

< S/PDIF SAMPLE RATE: When using the S/PDIF
input as your master clock source, use these radio
buttons to indicate the expected incoming sample
rate. Your selection here will be the only sample rate
available to your audio software. This ensures that
recordings will be made at the proper rate.
NOTE: These radio buttons are only available when Master Clock is set to
“S/PDIF In.”
< WORD CLOCK SAMPLE RATE: When using
the Word Clock input as your master clock source,
use these radio buttons to indicate the expected
incoming sample rate. Your selection here will be
the only sample rate available to your audio software.
This ensures that recordings will be made at the
proper rate.
NOTE: These radio buttons are only available when Master Clock is set to
“Word Clock In.”
< MULTITRACK DRIVER DEVICES: Delta 1010 has several different methods
of ensuring that its inputs and outputs record and playback your audio in sync.
These options are as follows:
• Single and In-Sync: This option ensures that all of your audio channels
will synchronize to the same clock and will record and playback together
with sample-accurate sync. This is the default setting.
• Independent: This option allows each input and output to be clocked
independently. This does not guarantee sample-accurate sync but may
place lower demands on your host processor, depending on the number of
physical audio channels currently in use.
