We have the same setup at our church (same board - different effects box). I have the effects coming out from the board on Aux 5 and going into effects box L/Mono. Then out from FX box L/Mono and into Stereo I/P Left. It works great except for the fact that when I turn the effects up in a particular channel, it begins to get louder in all Aux outputs (our monitors). I can't understand why this would happen unless I've got it hooked up wrong.
Granted, I haven't tried coming back into a free channel. Are there any other suggestions as to where I'm supposed to be bringing the TRS cable back into the board?
Thanks guys,
Eric
