The QM-AMP3X80MM is a professional power amplifier designed to provide exceptional audio performance as part of a complete MediaManager AV system or anywhere multi-channel amplification is required. Occupying just one rack space, the QM-AMP3X80MM provides three channels of amplification to complement the discrete stereo program and mono speech output channels featured on numerous Crestron QuickMedia® audio products. The QM-AMP3X80MM's first output channel delivers 80 Watts at 70 Volts to support distributed ceiling loudspeakers for speech reinforcement. The other two channels deliver 80 Watts each at 8 ohms or 110 watts at 4 ohms to drive a pair of program loudspeakers.

All inputs are balanced with fixed input gain optimized for use with MediaManager components. An efficient Class G power amp topology puts more output power in less space while generating significantly less heat as compared to conventional amplifier designs. With Cresnet communications built-in, the amp's power can be controlled and temperature monitored from any 2-Series or MediaManager control system.
