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.
