QSC

The RMXa Series amplifiers from QSC offer true professional-quality performance at an affordable price. Three 2-rackspace models range in power from 430 to 1200 watts per channel at 2 ohms. Two 3-rackspace models provide 2000 to 2500 watts per channel at 2 ohms. All five models feature a compact chassis less than 16” deep. RMXa amplifiers include a comprehensive set of features including XLR and 1/4” balanced inputs, Speakon® and binding post outposts for convenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.

The RMX 4050a is a “heavy duty” model designed to work as hard into 2 ohm loads as most competing amplifiers will at 4 ohms. Both the RMX 5050a and RMX 4050a feature a three-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 RMX4050a accomplish all this with a standard 15 amp plug

QSC’s RMX 5050a 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 RMX 5050a is optimized to deliver high levels of sustained power, extraordinary audio performance and road-proven reliability
