what type of outputs do you have on the mixer?
chances are you have 2 ways to go, what i usually do is run a L and R 1/4" from the main out of the board into the 3 & 4 mono inputs in the back (bottom) of the omni box...
if you have RCA outs you can run a single RCA-TRS 1/4" to the 3&4 stereo input on the back (top) of the omni box...
that way you still have 1 & 2 open and you can just plug in the front if you want to use the onboard pres....
hope that makes sense...
