The RMX Series amplifiers from QSC offer true professional-
quality performance at an affordable price. Four 2-rackspace
models range in power from 430 to 1200 watts per channel
at 2 ohms. Two 3-rackspace models provide 2000 to
2500 watts per channel at 2 ohms. All six models feature
a compact chassis less than 16" deep. RMX amplifiers
include a comprehensive set of features including XLR and
1/4" balanced inputs, Speakon
®
and binding post outposts
for convenient connectivity. User-defeatable clip limiters and
selectable low frequency filters optimize sonic performance.
RMX5050
QSC’s RMX5050 power amplifier represents state-of-the-art
in professional quality performance at an affordable price.
Perfectly suited for a wide range of sound reinforcement
applications including professional touring, performing
musicians, and mobile entertainers, the RMX5050 is optimized
to deliver high levels of sustained power, extraordinary audio
performance and road-proven reliability.
RMX4050HD
Like its smaller sibling (the RMX1850HD), the RMX4050HD
is one of two RMX “heavy duty” models designed to work
as hard into 2 ohm loads as most competing amplifiers will
at 4 ohms.
Both the RMX5050 and RMX4050HD feature a three-tier,
Class H design that is extremely efficient at real world power
levels. Less AC current is wasted and more available current
goes into producing useful audio power. 120 volt versions
of the RMX4050HD accomplish all this with a standard
15 amp plug.
