The new RMXa Series amplifiers from QSC offer true professional quality performance at a new affordable price. This power amplifier's compact chassis is only 2 rack spaces high and less than 16" deep. XLR and 1/4" balanced inputs and Neutrik Speakon® and binding post outputs allow users a convenient choice of connectors, while user-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.
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 RMXa 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.
RMXs 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 QSC to pack up to 2,400 watts of power in a chassis only 2 rack spaces and less than 16" deep. And unlike other designs, RMXa output devices are direct-mounted to the heat sink for optimum thermal coupling and cooling.
