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.
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" deep. And
unlike other designs, RMX output devices are direct-mounted to the
heat sink for optimum thermal coupling and cooling.
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.
