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. And with QSC's free 6 year warranty, the RMX is an even better value. *

Muscular Power Plant

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.

Superior Performance

RMX amplifiers deliver true studio-quality sound. A full complementary output circuit using the highest-grade linear output devices delivers ultra-low distortion (

• Low-noise variable speed fans with rear-to-front air flow keep amplifiers and racks cool.
• Compact size - up to 2400 watts in 2 rack spaces (RMX2450)
• Professional quality performance - incorporates road-proven QSC designs
• High-current toroidal transformers for greater two-ohm power and low noise
• Independent user-defeatable clip limiters reduce distortion
• Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
• Balanced 1/4" (6.3mm) TRS, XLR and barrier strip inputs
• Binding post and Neutrik Speakon outputs
• Front mounted gain controls for easy access
• Signal and Clip LED indicators to monitor performance
• Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
