The RMX 4050a amplifier from QSC offers true professional-quality performance at an affordable price. Three 2-rackspace range in power from 430 to 1200 w per channel at 2 ohms. Two 3-rackspace provide 2000 to 2500 w per channel at 2 ohms.

Description

RMX 4050a features a compact chassis less than 16” deep. RMX 4050a amplifier includes a comprehensive set of features including XLR and 1/4” balanced inputs, Speakon and binding post outposts for convenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.

The RMX 4050a is a “heavy duty” model designed to work as hard into 2 ohm loads as most competing amplifiers will at 4 ohms. RMX 4050a features a three-tier, Class H design that is extremely efficient at real world power levels. Less AC current is wasted and more available current goes into producing useful audio power. 120 volt versions of the RMX4050a accomplish all this with a standard 15 amp plug.

Features

4000 watt operates on a standard 15 amp plug (120V).
Dual mono, high-current power supply for increased reliability and performance.
Provides improved thermal performance yielding higher continuous power in 2 ohm stereo or 4 ohm bridged applications.
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.
Touch-proof binding post and Neutrik Speakon® outputs.
Compact size — up to 2500 watts in 2 rack spaces or 5000 watts in 3 rack spaces.
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.
