The
QSC RMX1850HD Power Amplifier delivers unmatched performance, clean, dynamic power, legendary sound quality and reliability that's needed for anyone using a power amp. QSC combined their rugged, high-output designs with the latest circuit technology to deliver unmatched performance at an affordable price.
The QSC RMX1850HD Power Amplifier has balanced XLR and 1/4 inch TRS inputs. Outputs include binding posts and Neutrik Speakon connections. These power amps are only 2 rack spaces tall and 15.9 inches deep. Other features of the RMX1850HD 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.

The QSC RMX1850HD Provides improved thermal performance for higher continuous power in 2-ohm stereo or 4-ohm bridged applications (a RMX 1850HD exclusive!). Specs include: 360W per channel @ 8 ohms, 600W/channel @ 4 ohms, 900W/channel @ 2 ohms, 1150W bridged mono @ 8 ohms and 1800W bridged mono @ 4 ohms.
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 inches deep. And unlike other designs, RMX output devices are direct-mounted to the heat sink for optimum thermal coupling & cooling.
Comprehensive Features
The RMX Series is packed full of professional features that increase performance and flexibility:
- The RMX 1850HD provides improved thermal performance that gives you higher continuous power in 2-ohms stereo or 4-ohms bridged applications (a RMX 1850HD exclusive!)
- 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 inch 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
