1 & 2, by plugging in only to the insert in (the red, or right side of the insert cable). This will

break the signal flow of the pre-amps to the inserts, allowing you to have 2 unbalanced line

inputs to the Delta H/W Ins 1 & 2. Pressing in the “To Ins 1, 2” switch will disconnect the

Mic/Instr channels, however, so you must chose one or the other.

The third method is to use the Instr In on Channels 1 & 2 of the Omni pre-amp. The “U”

marking shows a unity gain setting for the high impedance input when the Pad switch is

engaged. This will give you the equivalent, in level, of a line level input, with the option of

adjusting the gain. Understand, however, that this does send the signal through the Omni

pre-amp electronics.

12.4 Recording FX

There are occasions where you might want to record the outboard effects along with the

mic or instrument currently being recorded. You may also want to record effects for tracks

already recorded. Doing so will allow you to choose another effect, or “free-up” the effects

device for another vocal or instrument (assuming that you have a limited number of effects

units). In both cases, we recommend recording the effects onto their own audio tracks in

your software, allowing you to blend them with the principle track as you please. Also,

recording to the same track could cause a feedback loop if you’re recording effects at the

same time you’re recording the instrument or mic.

1. Assume that you have a vocal mic plugged into Mic/Instr Channel 1, recording onto

“Left PCM In 1 Delta.” The software outputs are set to Delta WavOut 1/2, and

according to monitor setup A (section 10.1), this is being sent to Delta H/W Out 1.

2. Use Omni Direct Out 1 as your effect send. Connect it to the input of your effects unit.

3. Take the outputs of your effects unit, and “return” them to Omni Line Ins 3 & 4. Set

two tracks of your music software to record “Left and Right PCM 3/4 Delta” (or one

track to “Stereo PCM” if your software records stereo tracks). Use the monitoring

scenario described in section 12.2.

You can use the “Effects Send” in a similar way, but return the effects in the fashion

described in step 3. The Effects Send will give you control over the levels going to the effect

unit. The ‘insert out’ point on Mic/Instr Channels 1 & 2 will also give you an effects send

(to be returned to Omni Line Ins), but only for instruments on that record path while you

are recording them.

12.5 Submixing MIDI Instruments

If you have more than four stereo MIDI instruments or sound modules (the number of

Aux Ins), then you might want to connect the MIDI gear to a mixer, and then connect the

stereo output of the mixer to an Omni Aux In. This is called “submixing.”

Also, you can use this “submix” technique to free-up Aux Ins, or to submix

effects returns. If you are following the “Using Direct Outs 1-4” for adding other

effects units while mixing, this will come in handy if you are running your MIDI

instruments as “virtual tracks.”
