I just hooked up my new QSC RMX 1450 which replaced my RMX 850. I'm running it in bridged mono into a SWR Goliath III 4X10 cab rated for 700w. My Preamp is a SansAmp RBI. The 1450 clips with the level of the RBI just around 12 O'clock (which is really loud) but gets very non-musical quick. It's a very abrupt, sharp, popping sound that can't be good. Channel 2 is turned down The channel 1 clip limiter is on 50Hz filter is on I'm using the same speakon as before +1 +2 on amp side any thoughts?
