HELP!!! The most bizarre things happened at a gig yesterday. The first issue was the newfangled Presonus StudioLive only had AUX 1 working for monitors so we went all ghetto and lived with it. Here's the truly scary part where the ghost came in... When I discovered that AUX 3 & 4 were not working properly (they were being fed by AUX 1 !!!) I removed the 3 & 4 1/4 balanced to XLR send wires from the board to that Crown Xti amp AND SOUND CONTINUED TO COME FROM THAT AMP!!!

So to recap - I had AUX 1 feeding 2 different amps and only 1 amp had a wire going into it. My head hurts - I'm gonna go take a nap now.

The simple answer is that the speakers were not plugged the way you thought they were.

THANK YOU! It just dawned on me that my front mounted nuetrik speaker output jacks on my rack were the culprit. So I was driving some of the monitors from a separate monobridge wired jack and the others were somehow working from the same amp and the normally wired front panel outputs for that particular amp and not the one below it that I thought it was plugging in to.

I ain't fraid of no ghosts!

So relieved to know that the board is not at fault and the amps are not going crazy - whew!

Thanks again.
