QSC RMX4050HD Power Amplifier
Limited Offer: 6-Year Warranty The best warranty promotion in the business has been extended. All PLX, RMX, or PL2 model amplifiers purchased now through December 31, 2005, will receive QSC's 6-Year Full Factory Warranty... FREE! Simply register the purchase online at www.qscaudio.com. The best professional warranty. QSC's 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 1 of 2 RMX "Heavy Duty" models designed to work as hard into 2-ohm loads as most competing amplifiers will at 4-ohms. With a 3-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 in. 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. The RMX 4050HD provides improved thermal performance that gives you higher continuous power in 2-ohms stereo or 4-ohms bridged applications RMX4050HD Power Amplifier Features Dual mono, high current power supply for increased reliability and performance 3RU chassis only 16 in. deep Professional quality performanceΦincorporates road-proven QSC designs High-current toroidal transformers for greater 2-ohm power and low noise Independent user-defeatable clip limiters reduce distortion Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom Balanced 1/4 in.
