M-Audio Omni i/o [28/30] Alternate omni setups

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
