• 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.
