This review is from: QSC RMX850 Power Amplifier

I've had it powered up for years without a failure. The sound is loud and clear. The input and output connector varieties made it easy to plug in and go. It's affordable. There are a few features (eg, high pass filters, output options) that you'll set and soon forget with DIP switches on the back panel. Instrumentation is minimal. The fan is quiet, but not inaudible in a quiet room. It's heavy.

This review is going to be easy. I've had this amp for five years. It sounds great. Built like a tank. NEVER had a single problem with it. Very powerful. I'd buy another without hesitation.
