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 120 volt versions of the RMX 4050HD accomplish 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 2 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
