THE FRONT PANEL
The Omega’s front panel offers the
following features:
• Mic 1-2 Gain
These knobs adjust the input gain levels
of the Mic 1 and Mic 2 inputs.
• Line 1-4 Gain
These knobs adjust the input gain levels
of the Line 1 through Line 4 inputs.
• Peak LEDs
These LEDs will light when the input
signal is within 5dB of analog clipping. If
the Peak LEDs flicker occasionally, the
signal is approaching clipping levels,
but does not necessarily indicate
distortion or actual clipping.
• USB Assign
These buttons select which USB audio
bus (USB 1-2 or 3-4) that signal is
streaming up to the computer on.
• Monitor Assign
These buttons select whether analog
audio sources are heard in stereo or
mono. Audio sources plugged into the
Omega are placed accordingly in the
analog stereo field. Odd numbered
inputs are routed to the left channel
and even numbered inputs are routed
to the right channel.
The Front PanelOMEGA
TM

V
• Monitor Mix Control
The Omega gives you the ability to
monitor your analog input signals while
recording without the delay incurred by
A/D/A converters and computer
recording latency. This zero-latency
analog monitoring is controlled by the
Monitor Mix knob, which you can use to
blend and adjust the ratio between
OMEGA analog inputs and computer
audio playback. Any signal coming in
on the S/PDIF input is converted to
analog and sent to the mix control so
that you can monitor this input directly
just like an analog input. To listen to just
the source input signal, turn the Mix
knob fully left to Direct. The Output
from the Mix control is routed directly to
the Line and Headphone outputs. This
ability to blend and control the relative
levels of computer audio playback and
latency-free live analog inputs is
effective when overdubbing.
• Output Level
This knob controls the overall output
level of the Omega’s Line and
Headphone outputs.
• Meter Assign
This switch assigns which signals (signals
assigned to USB 1-2 bus or USB 3-4 bus)
are being monitored by the Omega’s
meter ladder. This LED Meter shows the
signal level into the A/D converters.
When the Meter’s Clip LEDs light,
analog input signals are clipping the
A/D converter. Adjust the Mic and Line
gain knobs so that the -6 dB yellow LED
only lights occasionally.
• USB LED
The USB LED indicates that the Omega
is communicating with your computer
via USB and audio and MIDI signals can
pass in and out of the system. If the USB
LED is blinking, the Omega is not
communicating with your computer.
• +48V LED
This LED indicates that 48 Volt phantom
power is active on the Mic 1 and 2
inputs. These inputs provide phantom
power for condenser microphones that
require it to operate. Phantom Power is
activated by the switch labeled +48V
Phantom on the bottom of the rear
panel of the Omega.
• S/PDIF Assign
This button assigns the S/PDIF digital
input to the USB 1-2 audio bus. When
S/PDIF is enabled, only digital audio can
use the USB 1-2 bus and any analog
inputs that were assigned to USB 1-2 are
disabled. Analog inputs can still be
assigned to the USB 3-4 bus while the
S/PDIF Assign is enabled, allowing both
digital and analog audio to be
recorded simultaneously.
• S/PDIF Assign LED
This LED lights when the S/PDIF input is
assigned to the USB 1-2 bus.
• S/PDIF Lock LED
The LED lights when the S/PDIF input has
locked in with the Omega. If this LED is
not lit, digital signal can not be
received from external devices via the
S/PDIF input.
• Headphone Output
The Headphone Output
accommodates stereo headphones
with a 1/4” stereo plug.
• Instrument Input Jack
This 1/4” jack accepts unbalanced
instrument sources such as electric
guitar, acoustic guitar with a pickup,
and electric bass. The input gain is
adjusted using the Line 3 knob on the
front panel respectively. When an
instrument is plugged in, it disables the
Line 3 audio input.
Lexicon Professional
®
The Front Panel
4
THE REAR PANEL
The OMEGA’s rear panel offers the
following features:
• Line In 1-4
These 1/4” inputs can accept both
balanced and unbalanced audio
sources. The input gain is adjusted
using the Line 1-4 knobs on the front
panel respectively.
• Line Out L/R
These outputs support balanced TRS or
unbalanced TS 1/4” connections. These
outputs can be connected to a mixing
board, power amplifier, or another line
level input.
• Mic 1-2 Inputs
These balanced XLR inputs feature high
quality dbx
®
mic preamps designed
specifically for microphone use. The
input gain is adjusted using the Mic 1-2
knobs on the front panel respectively.
• -20dB Pad
The -20dB pad is a resistive attenuator
that drops the level coming from the
mic input jacks. Its purpose is to give
you a way of preventing overload of
the preamp when incoming signals
become excessive. Another purpose is
to change the preamp’s mic input into
a line input. The Omega provides a
pad of -20dB. This means when the
The Rear Panel
OMEGA
TM
5
Lexicon Professional
®
pad is on, the net gain of the preamp
is 20dB lower than normal.
• Insert 1-2
Each mic input is equipped with a TRS
insert point. Inserts provide a send and
return of the input channel’s signal
directly after the mic preamp and
before the A/D converter. You can
insert any line level analog processors
such as compressor or equalizer for
pre-processing of the mic signal before
it is recorded. The tip is send and the
ring is return.
• S/PDIF In and Out
The S/PDIF in and out ports are
unbalanced phono (RCA) connectors
that transmit and receive either 16-bit or
24-bit two-channel audio stream.
S/PDIF is used in many professional and
consumer CD and digital audio
recorders. It is recommended to use
75-Ohm coaxial cable for S/PDIF
transfers and keep the cable length to
a maximum of 10 meters to minimize
interference and data dropout. The
S/PDIF output only sends the stereo
signal that is returned from the
computer. Thus it is not affected by the
setting of the Mix control.
• +48V Switch
This switches on the phantom power to
the Mic 1 and Mic 2 inputs. Dynamic
microphones do not require phantom
power to operate, but are not harmed
by it. Most condenser microphones do
require phantom power to operate. If
you are unsure about the phantom
power requirements for your
microphone, consult your microphone’s
documentation or contact the
manufacturer.
• USB Port
The USB Port is used to connect the
Omega to your computer. A standard
USB cable is included. The Omega is
compatible with USB 2.0 ports, but the
USB 2.0 bus will switch to the slower USB
v1.1 speed to work with the Omega.
• MIDI In and Out
The MIDI jacks provide MIDI input and
MIDI output to and from your computer.
Connect your MIDI keyboards, sound
modules, and external controllers here.
• Power Jack
Use only the supplied PS0913-B power
supply to power the Omega.

MAKING CONNECTIONS
The OMEGA is both an 8 x 4 x 2 mixer
and USB audio interface that can used
in a variety of audio setups. This section
describes how to make basic
connections for the following
applications:
• Monitoring Audio
• Recording Audio
• Connecting a Recorder for
Mixdown
Monitoring Audio
Omega Line Outputs play the audio
that is routed in Pro Tracks Plus™ or
BIAS Deck SE
TM
to Analog Outputs 1-2,
and can provide left and right outputs
to a two-track deck for mixdown, or to
another stereo destination.
Omega Line Outputs offer 24-bit
digital-to-analog converters capable
of nominal output of +4 dBu/+2 dBV
(balanced/unbalanced signal). The
connectors are TRS jacks; unbalanced
TS connectors are also supported.
Connecting headphones:
1. Connect headphones to the
Headphone jack located on
the front panel of the Omega.
The Headphone Output
accepts a 1/4” TRS connector.
2. Adjust headphone volume via
the Output Level knob.
Connecting to monitor speakers with a
power amp or self-powered monitor
speakers:
1. Using 1/4” cables, connect the
Line Outputs on the rear panel
of the Omega to the
appropriate inputs on your
mixer, power amp, or powered
speakers.
2. Adjust headphone volume via
the Output Level knob.
Connecting to a home stereo:
1. Using 1/4” cables, connect the
Line Outputs on the rear panel
of the Omega to the
appropriate inputs on your
stereo.
Recording Audio
Digital and analog audio sources can
be connected directly to the Omega.
Analog Audio:
Analog audio signals are output by
microphones, synthesizers, mixers, and
instruments with magnetic pickups.
Of these sources, microphones and
magnetic pickup instruments output
the quietest signals, and generally
require the most amplification.
Keyboards, preamps, and mixers
output “line level” audio, which varies
with each device between the -10 dBV
and +4 dBu standards.
To connect an analog audio source:
1. Plug an XLR or TRS cable
directly into the desired
Mic/Line Input on the Omega.
The Mic Inputs accept XLR
connectors, the Line Inputs
accept TRS connectors.
OMEGA

Making Connections
To activate Phantom Power:
If your microphone requires phantom
power, first make sure the microphone
is connected, then press the Phantom
Power switch (labeled +48V). The +48V
LED on the front panel indicates the
phantom power is active. If your mics
don’t need phantom power, it is best
to turn it off.
Using the Analog Inserts:
The analog inserts require a 1/4” TRS to
2 x 1/4” TS adapter cable. The signal
from the tip should be routed to the
input of your outboard processor and
the output of your processor should be
routed to the ring.
Digital Audio:
Digital audio represents analog
waveforms using thousands of digital
samples of the analog waveforms
each second. All audio on your hard
drive in a Pro Tracks Plus
TM
or Bias Deck
SE
TM
session is digital audio.
The Omega provides digital inputs and
outputs for S/PDIF format digital audio.
Connecting a S/PDIF device to the
Omega:
1. Use two 75 Ohm coaxial
cables with male RCA
connectors on both ends.
2. Connect the device’s S/PDIF
output to the Omega’s S/PDIF
input jack, and the device’s
S/PDIF input to the Omega’s
S/PDIF output jack.
Connecting a Recorder for
Mixdown
After you record and mix your sessions
in either Pro Tracks Plus
TM
or Bias Deck
SE
TM
, you may want to mix them down
to a DAT, audio cassette, or other
stereo 2-track recording device.
Connecting an Analog Deck:
Connect your recorder (cassette deck
or other analog device) to the Line
Outputs on the back of the Omega.
The Left and Right Line Outputs should
be routed to the left and right inputs,
respectively, on your recorder. These
outputs are TRS jacks. You may need
adapter cables if your mixdown deck
has RCA jack inputs.
Connecting a Digital Deck:
If you have a DAT or other device that
accepts S/PDIF connections, connect it
to the S/PDIF In and S/PDIF Out RCA
jacks on the back of the Omega.

MACINTOSH®SOFTWARE
SETUP
You must consult the Software
Installation Guide packaged with the
software CD-ROMs inside the Omega
box to ensure the successful installation
of the recording software and USB
setup.
If you haven’t already installed the
your software, please do so before
continuing on to the next section.
Mac OS
A USB device must initialize itself with
the host computer to operate
correctly. The Omega Studio
comprises several devices (audio and
MIDI) and each of those must be
initialized. Some Apple
®
Mac
computers will not recognize all of
these devices if the Omega Studio is
powered on (and connected to the
USB port) before the computer is
turned on. The simplest way to avoid
problems is to either turn on the
Omega Studio or connect it to the USB
port after the computer is booted.
However, there is a way to fore a
reinitialization after the computer is
running.
1. Make sure you close any
applications which are using
the Omega Studio.
2. Press the Mic 1-2 USB Assign
button and the Line 3-4 USB
Assign button at the same time
and then release them
simultaneously. The blue USB
light will flash and after three
seconds the Omega Studio will
be properly initialized.
