The QSC's RMXa Series amplifiers is offering a true professional-quality performance at an affordable price. It have a three 2-rackspace models range in power from 430 to 1200 watts per channel at 2 ohms. At 2 ohms also, there are Two 3-rackspace models providing 2000 to 2500 watts per channel. All these five models are featuring the same compact chassis less than 16” deep. RMXa amplifiers are including a comprehensive set of features which includes XLR and 1/4” balanced inputs, Speakon® and binding post outposts for convenient connectivity. Selectable low-frequency filters and user-defeatable clip limiters optimize sonic performance. QSC RMX4050a is a professional quality performance, incorporating road-proven QSC designs.

RMX 4050a

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. Both the RMX 5050a and RMX 4050a feature 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

• Compact size — up to 2500 watts in two rack spaces, or 5000 watts in three rack spaces
• 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
• The 4000-watt RMX4050a operates on a standard 15 amp plug (120V)
• Both the RMX4050a and the RMX5050a feature a dual mono, high-current power supply for increased reliability and performance
• The RMX4050a's particularly exceptional combination of cooling capacity and electrical efficiency provides robust thermal performance suitable for high continuous power in 2-ohm stereo or 4-ohm bridged applications.
• Balanced 1/4-inch (6.3 mm) TRS, XLR, and barrier strip inputs
• Touch-proof binding post and Neutrik Speakon® outputs
• Front mounted gain controls for easy access
• Signal and clip LED indicators for monitoring 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
