　　Item Description.

　　QSC's RMX 4050HD power amplifier stands for the cutting-edge in professional-quality efficiency at a budget-friendly rate. Perfectly suited for a large range of sound reinforcement applications including expert touring, carrying out artists, and mobile DJs, the RMX4050HD is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven dependability.

　　Like its smaller sized sibling (the RMX 1850HD), the QSC RMX 4050HD is 1 of 2 RMX "Heavy Duty" designs created to work as hard into 2-ohm loads as many competing amplifiers will at 4-ohms. With a 3-tier, Class H design, the RMX4050HD is very reliable at real world power levels. Less AC current is lost and more enters into producing helpful audio power. The QSC RMX 4050HD accomplishes all this with a conventional 15-Amp plug.

　　Like all RMX amps, the QSC RMX 4050HD includes well balanced 1/4 in. TRS, XLR and barrier strip inputs, binding posts and Neutrik Speakon outputs, front-mounted gain controls, plus signal and clip LED signs to keep an eye on efficiency.
