QSC RMX1850-HD
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.

I've had this 18050HD amp for about 7 years now and mainly use it in bridge mono mode to power my sub with little effort. It pumps out very deep you can feel bass with a peak of 1100 (bridged mode) watts. QSC stands for quality and reliability.
