3. Start to raise the Omni gain control while testing your microphone or guitar.

If you are using an instrument with volume controls, start with it on the

highest setting, then play to test the level. Raise the Omni gain control to

between 9 o’clock and 12 o’clock, or until you see the green signal LED start

to light.

4. Continue to test the mic or instrument, making sure that the clip LED never

stays lit for too long. If the clip LED lights easily with the gain control set to

9 o’clock or less, try pressing the “Pad” switch (this will trim the input signal

by 20dB).

5. Bring up the level meters in the Delta panel Monitor Mixer. The signal level

that you see at the H/W Ins will ultimately be your record levels, as they

should be identical to the level meters in your software. Adjust the Omni

gain controls until the signal nearly reaches the red area. It should never hit

the top of the meter.

NOTE: If you seem to have to turn the Omni gain up past 2 o’clock

and still do not register adequate levels in the Delta Monitor Mixer,

go to the Delta panel Hardware Setting page. Adjust the Variable

Signal Level on your particular input to a lower setting (Consumer

or –10) in order to reduce headroom.

Once you have set the record levels, you may begin to adjust the listening or

monitoring levels for those channels. If you are using the Delta Monitor Mixer,

setting the fader level in the Delta Monitor Mixer page will affect only the

monitoring levels, and will not affect record levels. This is also true of the faders

in your software if you are monitoring through your software. Changing the

monitor level will not affect the record level.

To set record levels for the Omni Line Ins:

Since there are no gain controls for the line inputs, you will need to adjust the

output control on the device that you are recording. If your device runs at a line

level other than +4, set the Variable Signal Level in the Delta panel to

“Consumer” or –10dB. If you are getting low record levels with the device

output level turned up, lower the Variable Signal Level in the Delta panel. Or, if

turning up the output levels introduces noise, lower the output level and then

lower the Variable Signal Level in the Delta panel.

10.4 Record Levels Using the Inserts

“Inserts” give the user an insertion point in a signal flow for adding signal

processing. Each Omni Insert provides an unbalanced output from the record

channel, then brings that unbalanced signal back into the record channel, via a
