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.

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.

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" 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.

Features:

* Compact size--up to 2400 watts in 2 rack spaces
* Professional quality performance--incorporates road-proven QSC designs
* High-current toroidal transformers for greater two-ohm power and low noise
* Independent user-defeatable clip limiters reduce distortion
* Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
* Balanced 1/4" (6.3mm) TRS, XLR and barrier strip inputs
* Binding post and Neutrik Speakon outputs
* Front mounted gain controls for easy access
* Signal and Clip LED indicators to monitor performance
* Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
* 3-year warranty plus optional 3-year extended service contract

Description

QSC’s RMX 4050HD power amplifier represents the state-of-the-art in professional quality performance at an affordable price. Perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians, and mobile DJs, the RMX 4050HD is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven reliability.

Like its smaller sibling (the RMX 1850HD), the RMX 4050HD is one of two RMX “Heavy Duty” models designed to work as hard into 2-ohm loads as most competing amplifiers will at 4-ohms. With a three-tier, Class H design, the RMX 4050HD is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. The RMX 4050HD accomplishes all this with a standard 15-Amp plug.

Like all RMX amps, the RMX 4050HD features balanced 1/4" TRS, XLR and barrier strip inputs, binding posts and Neutrik Speakon™ outputs, front-mounted gain controls, plus signal and clip LED indicators to monitor performance.

Features:

* The RMX 4050HD provides improved thermal performance that gives you higher continuous power in 2-ohms stereo or 4-ohms bridged applications
* Dual mono, high current power supply for increased reliability and performance
* 3RU chassis only 16" deep
* Professional quality performance—incorporates road-proven QSC designs
* High-current toroidal transformers for greater two-ohm power and low noise
* Independent user-defeatable clip limiters reduce distortion
* Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and
increase headroom
* Balanced 1/4" (6.3 mm) TRS, XLR, and barrier strip inputs
* Binding post and Neutrik Speakon™ outputs
* Front mounted gain controls for easy access
* Signal and Clip LED indicators to monitor performance
* 3-year warranty. An optional 3-year extended service contract is available. Ask your dealer for details.
