The QSC RMX 4050a Power Amplifier is a heavy duty amp designed for mid-size to large systems and works as hard into 2 ohm loads as most competing amps will at 4 ohms. The three-tier, Class H design is extremely efficient at real world power levels so you always get a powerful, clean sound. QSC designed the RMX 4050a so that less AC current is wasted and more available current goes into producing useful audio power. All this is accomplished with a standard 15 amp plug.
