The new RMX series amplifiers give you clean,
dynamic power with QSC's legendary sound quality and reliability that pros
depend on. QSC combined their rugged, high-output designs with the latest
circuit technology to deliver unmatched performance at a new breakthrough price.
RMX amps have balanced XLR and 1/4 in. TRS inputs. Outputs include binding posts
and Neutrik Speakon connections. These stereo power amps are only 2 rack spaces
tall and 15.9 in. deep. Other features include ultra low distortion (.05% THD),
a low-noise variable speed fan with rear-to-front air flow to keep your
amplifier and racks cool, and selectable low-frequency filters to protect your
speakers and increase headroom. QSC power amps are backed by a 3-year
transferable warranty.

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) & 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 & less than 16" deep. And
unlike other designs, RMX output devices are direct-mounted to the heat sink for
optimum thermal coupling & cooling.
Features:
- 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 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.
