Putting the amps in a different room would definitely eliminate the fan noise. Some pro amps have fans whose run speed is regulated by demand so at low temperature they hardly turn, which would be normal operation in a home. I considered changing the fan as well as the intensity of blue LED pilot light. The light would be no problem but for the fan would have to insure it isn't cooling other, non load sensitive components, like heatsinks for voltage regulators, if any, that might be mounted in the airstream. If the amps were not behind glass I would investigate. The bright blue LED pilot light though is quite annoying... when the glass doors are closed I don't see it owing to the wood frame of the glass but can't easily see the output indicators either. If I wasn't so lazy would modify the pilot light arrangement but other than that I love these amps. One feature these QSC amps have is at first soft, then steeply ramped limiting above clipping threshold which of course protects speakers, notably tweeters. I've only seen the clip indicator light once and that was on the rear, less efficient JBLs. This is the only system I've owned that I didn't turn it up 'all the way'... it is gets so intensely loud I back off from doing it. Like that Corvette that will do an honest 160 mph.... gets intense at 140, where one starts thinking about stress on tires, wheels, nuts and bolts, and the sheer speed of it, and decides 140 is enough to experience. It's nice and smooth down low though, very easy listening.
