The RMX Series amplifiers give you clean, dynamic power with the legendary QSC sound quality and reliability that pros depend on. The RMX Series deliver unmatched performance at a new breakthrough price.

Comprehensive Features
The RMX Series is packed full of professional features that increase performance and flexibility:
The RMX 1850HD provides improved thermal performance that gives you higher continuous power in 2-ohms stereo or 4-ohms bridged applications (a RMX 1850HD exclusive!)

Independent defeatable clip limiters reduce distortion without sacrificing peak performance.

Selectable low-frequency filters boost system response, protect speakers and ensure low-end tightness by more precisely matching the amplifier's range to the loudspeakers.

Barrier strip, XLR and 1/4" balanced inputs plus Speakon and binding post outputs provide easy connections.

Low-noise variable speed fans with rear-to-front air flow keep amplifiers and racks cool.
Proven Reliability
With over 30 years of building amplifiers for the largest touring companies and venues around the world, you can count on QSC's reputation for designing the most reliable amps available.
