Product Description for the QSC RMX 1850HD Power Amplifier

Amplifier

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.
