QSC USA 850 two channel professional power amplifier in black, rack mount chassis with mounting ears. Rear panel has Gain 1 and Gain 2 controls, 1/4 inch channel inputs, a barrier strip input block, binding post speaker outputs, and a stereo/bridge switch. Front panel has a power switch, AC breaker, and power and clip indicator LEDs.
Rear label reads Model USA850, 425 W per channel at 4 ohms, 120 VAC. It powers on and the green power LED lights, as shown in the photos. I have not tested audio output, so performance through speakers is unknown. Cosmetic condition is used, with scuffs, paint wear, and chipped paint around the rack ear mounting slots. Attached power cord included, no other accessories. Photos show the exact item and its condition. Packed carefully in a new sturdy box with heavy duty bubble wrap. Please feel free to ask any questions you may have. I will often reply quickly, unless foraging for mushrooms.
