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 breakthrough price.
The power supply is the heart of an amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The RMX uses a powerful high-current toroidal transformer and ample filter capacitance to ensure generous energy reserves. This makes a critical difference in sound quality, allowing the amp to effortlessly punch out high level transients, even when driving abusive 2-ohm speaker loads.
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.
