QSC RMX 5050 Power Amplifier: More Power Than You Oughta Have!

QSC's RMX 5050 power amplifier represents the state-of-the-art in professional quality performance at an affordable price. Perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians and mobile entertainers, the RMX 5050 is optimized to deliver high levels of sustained power, extraordinary audio performance and road-proven reliability. Like its smaller sibling (the RMX 4050HD), the RMX 5050 features a 3-tier, Class H design. The RMX 5050 is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. It'll easily crank out over 1000 watts per side at 8 ohms! The RMX 5050 uses the best available component upgrades to increase peak power by 25% over the RMX 4050HD. Like all RMX amps, the RMX 5050 features balanced 1/4" TRS, XLR and barrier strip inputs, binding posts and Neutrik Speakon outputs, front-mounted gain controls, plus signal and clip LED indicators to monitor performance.

        According to QSC this amp cannot be converted to 220. Some Crowns have the 220 option though.
