[QUOTE="Jason Lavoie, post: 125555, member: 159"] Re: QSC CMX500Va Amp in Bridge mode problem It's not about the level control, it's that when you bridge the amp you're using the + output of the left and the right amps at the same time, so if either wire is shorted to ground it will trip up the amp. In stereo operation the - of each amp is ground, so theoretically one leg of the speaker line could be grounded and not have much of an effect. This is all just speculation though until you get a chance to diagnose. ps: if the amp is shutting down periodically due to the fault, I'm sure you could take it offline for a minute to diagnose?
