QSC RMX 5050a - Power Amp 2 x 1800W @ 4ohms

The QSC RMX 5050a power amplifier is perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians, and mobile entertainers. The RMX5050a is optimized to deliver high levels of sustained power, extraordinary audio performance and road-proven reliability.

Like its smaller sibling (the RMX 4050a), the RMX 5050a features a three-tier, Class H design. The RMX 5050a is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. The RMX 5050a uses the best available component upgrades to increase peak power by 25% over the RMX 4050a.

Like all RMX amps, the RMX 5050a 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.
