The other day I experimented with my current rig Aggie db680/QSC plx3402 (stereo one channel) into Berg HT322, I've always thought that the rig wasn't quite loud enough, I know that the QSC 3402 needs some juice so I dialed in tone with the gain set to 11.00 and the pre-amp master cranked all the way up. I suddenly discovered that the tone somehow opened up and became clearer, not just louder. But it made me wonder if cranking the pre-amp (master) full would do some harm, will the pre-amp clip, how would this affect the power amp or speaker? I then took the speaker plug out and turned the QSC full up with the same pre-amp setting and the clip light on the QSC just blinked when plugging hard. Does this mean that now I'm running the QSC on full power.
