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.
Features:
- 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.
