From Our Research Team:

A Clean, Reliable Power Amp!

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.

QSC RMX1450 Power Amp at a Glance:
  • Generous energy reserves for premium sound quality
  • Ultra-low distortion for studio-quality sound
  • Professional features for clean, reliable performance
  • Proven reliability

Generous energy reserves for premium sound quality
The power supply is the heart of an amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The RMX1450 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 RMX1450 to effortlessly punch out high level transients, even when driving abusive 2-ohm speaker loads.

Ultra-low distortion for studio-quality sound
The QSC RMX1450 amplifier delivers true studio-quality sound. A full complementary output circuit using the highest-grade linear output devices provides ultra-low distortion (<0.05% THD) and a ruler-flat frequency response. SMT (Surface Mount Technology) triples small-signal component density, enabling QSC to pack up to 2400 watts of power in a chassis only two rack spaces and less than 16" deep. And unlike other designs, RMX output devices are direct-mounted to the heat sink for optimum thermal coupling and cooling.

The RMX1450 is packed full of professional features that increase performance and flexibility. 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.
