[. . . ] RMX5050 QSC's RMX5050 power amplifier represents 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 RMX5050 is optimized to deliver high levels of sustained power, extraordinary audio performance and road-proven reliability. RMX4050HD Like its smaller sibling (the RMX1850HD), the RMX4050HD 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. Both the RMX5050 and RMX4050HD feature a 3-tier Class H design that is extremely efficient at real world power levels. Less AC current is wasted and more available current goes into producing useful audio power. 120 volt versions of the RMX4050HD accomplish all this with a standard 15 amp plug.
