12. Alternate Omni Setups
These are some advanced techniques. Once you master the Omni basics, you
may want to try some of these variations.
12.1 Recording with Four Pre-Amps
The Omni provides you with 2 pre-amp channels, Mic/Instr Channel 1, and
Mic/Instr Channel 2. If you need to use two more pre-amps, you may connect
the line outputs of two pre-amp channels to Omni Line Ins 3 & 4.
The M Audio DMP-2 is a perfect companion to the Omni pre-amps, and will
give you the same high quality sound. If you already own a mixer with pre-
amps built-in, you can take a direct, buss, or insert output from the pre-amp
channels, and connect this to Omni Line Ins 3 & 4.
12.2 Monitoring While Recording to Four Tracks
If you are using the Delta Monitor Mixer to monitor your inputs while recording
(as opposed to monitoring through a program using the ASIO or EASI drivers),
then follow this monitoring scenario when recording four tracks (or more than
two inputs to more than two tracks).
1. In your music software, set the four Omni record channel inputs to record to
Delta Left and Right PCM Ins 1/2 and 3/4, respectively. Set them to output
to Delta WavOuts 1/2 and 3/4.
2. In the Delta Patchbay/Router page, set H/W Outs 1/2 to “Monitor Mixer”
as the source. Set H/W Out 3/4 to “H/W In 3/4” as the source.
3. In the Delta Monitor Mixer page, unmute and raise the faders for H/W In
1/2, but not H/W In 3/4. Unmute and raise the faders for H/W Out 1/2,
and also for H/W Out 3/4.
This setup will prevent you from hearing H/W Outs 3/4 both from Omni
Channels 1 &2, and from 3 & 4, while recording and playing back. You will hear
H/W In 3/4 from H/W Out 3/4 while recording, and from H/W Out 1/2
(Monitor Mixer) when playing back.
12.3 Recording Four Line Inputs
The Omni is set up with 2 mic/instrument inputs that are connected to the Omni pre-amp
(Mic/Inst Channels 1 & 2), and 2 line inputs connected directly to the Delta H/W Ins (Line
Ins 3 & 4).
If you wish, at some time, to record four devices to line inputs, there are three choices. You
can use the Aux In 1, and press in the “To Ins 1, 2” switch. This will give you 2 unbalanced
line inputs to the Delta H/W Ins 1 & 2. Alternately, you could use the “Inserts” on channels
