The new 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.
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 (<0.05% THD) and a ruler-flat frequency response. SMT (Surface Mount
Technology) triples small-signal component density, enabling us to pack up to
2400 watts of power in a chassis only 2 rack spaces and less than 16 in. deep.
And, unlike other designs, RMX output devices are direct-mounted to the heat
sink for optimum thermal coupling and cooling.
Features:
- The RMX Series 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 in. 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.
