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.

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.

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

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 MIDIJacks provide MIDI input and MIDI output to and from your computer. Connect your MIDI keyboards, sound modules, and external controllers here.

PowerJack

Use only the supplied PS0913-B power supply to power the Omega.

MAKING CONNECTIONS

The OMEGA is both an 8 × 4 × 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™ 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 +4dBu / +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.

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 × 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™ or Bias Deck SE™ 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™ or Bias Deck SE™, 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.
