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.

QSC RMX4050a Power Amplifier
The RMXa Series amplifiers offer true professional-quality performance at an affordable price. With 1400 W/CH into 4 ohms and 2000 W/CH into 2 ohms all in a chassis that is less than 16 inch deep the RMX4050a is perfectly suited for performing musicians and mobile entertainers.
