Product Description
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 new breakthrough price. 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. 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. 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 loudspeak...QSC RMX2450 Stereo Power Amplifier Review
I use three of these and am buying a fourth. Two are bi-amping a $40,000 stereo mastering system in my studio. These replaced a finiky pair of class A power amps whose paint cost more than these entire amps.The sound quality is ruthless and musical as hell. I did have to recalibrate the way I had my monitor speakers aimed, because every amp works a speaker response and delivery its own way. However these amps told me more truthfully where the speakers needed improvement setup wise...
Before you think I am mad let me add I used to be a Krell salesman and McIntosh Labs salesman. I know power amps. My front end is all class A. I studied the topology of these amps and concluded they just might be a "sleeper" in the design department as they use SMDs and a bunch of HiFi tricks.
Plus they are freakin loud and clean and never blow drivers with unlimited clean power... Unlike my Class A amps which blew up a monitor when they choked.
I am finally buying another one to actually use as a PA amp and make an honest amp out of it. I would not say there are no other "deals" to be found out there in the world of commercial sound re-inforcement. The only other design that excited me was the Crown K series which I believe is discontinued. So this was the best I could find four years ago.
Try them. You may like them...
