This is a rack of amplfiers used in our studio.
The CROWN D-150 amp, center of rack, controls the levels sent to the studio monitors. ***NEVER***turn these amps up past 50% of their availalable level. Remember, to save your ears, don't mix at club (real loud) levels. You could suffer a serious hearing loss!
by the way, the QSC amp (on top in this photo) controls the levels sent into the headphones in room 210 at Skidmore.
