6. Basic Playback Setup for the Omni I/O
This section will get you setup for playback and monitoring, as well as for
mixing down when your project is complete (though you may make changes in
your setup at that time). A discussion of the Omni components becomes more
detailed in sections 9 through 11.
Install your Delta card first, according to the Delta installation procedure found
in the Delta 44 or 66 manual. In the step by step instructions that follow, the
items in quotations such as “9v AC Power Jack” relate specifically to numbered
items on the front and back panels of the Omni I/O.
1.
Make sure that the host computer is powered off. Using the shielded 15 pin
to 15 pin cable that came with your Delta card, connect one end of the cable
to the D-sub connector on the Delta card, and the other end to the “15 Pin D-
sub Connector” on the back of the Omni I/O.
This cable is a shielded audio cable, and connects the Omni to the four
analog inputs on the Delta card (H/W Inputs 1 through 4). The 15 pin to 15
pin cable also connects the Delta H/W Outs 1 through 4 to the Omni mixer,
and also to the “Omni Direct Outs 1-4.”
2. Plug the 9v AC power supply into the wall outlet, and connect the 2.5 mm
plug into the “9v AC Power Jack” on the back of the Omni.
3. Connect the “Monitor Outs” of the Omni to the inputs of your monitoring
system. If your monitoring system’s inputs are unbalanced, use a cable with
a 1/4” Tip-Sleeve plug on the Omni monitor outs, with the appropriate plug,
such as 1/4” TS, RCA, etc., into the monitoring system inputs.
If your monitoring system’s inputs are balanced, use a cable with a 1/4” Tip-
Ring-Sleeve plug on the Omni monitor outs, with the appropriate plug, such as
1/4” TRS, XLR, etc., into the monitoring system inputs.
NOTE: A mixer such as the Omni is in itself a pre-amp. This means
that you can connect the Monitor Outs to a power amp or directly
to powered speakers. You can also connect the Monitor Outs to an
integrated amplifier such as a home stereo (though you may not
need as much level from the Omni Monitor Control).
4. Plug the audio outputs from your MIDI keyboards, sound modules, and
drum machines into each of the four Omni stereo “Aux Ins.” Use a cable that
is a single 1/4” TRS plug to two 1/4” TS plugs, (sometimes referred to as an
“insert cable”), or cabling that is similar while appropriate to your MIDI
modules outputs.
