QSC RMX4050HD Power Amplifier - RMX4050HD

The QSC RMX 4050HD 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 DJs, the RMX 4050HD is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven reliability. Like its smaller sibling (the RMX 1850HD), the RMX 4050HD is one of two RMX Heavy Duty models designed to work as hard into 2-ohm loads as most competing amplifiers will at 4-ohms.

With a three-tier, Class H design, the RMX 4050HD is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. The RMX 4050HD accomplishes all this with a standard 15-Amp plug. Like all RMX amps,the RMX 4050HD features balanced 1/4 inch 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.

QSC RMX Series amplifiers give you clean, dynamic power with the legendary QSC sound quality and reliability that pros depend on. We combined our rugged high output designs with the latest circuit technology to deliver unmatched performance at a new breakthrough price.

Muscular Power Plant
The power supply is the heart of an amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The RMX uses a powerful high-current toroidal transformer and ample filter capacitance to ensure generous energy reserves. This makes a critical difference in sound quality, allowing the amp to effortlessly punch out high level transients, even when driving abusive 2-ohm speaker loads.
