Features

Professional quality performance—incorporates road-proven QSC designs
The 4000 watt RMX 4050a operates on a standard 15 amp plug (120V)
Both the RMX 4050a and RMX 5050a feature a dual mono, high-current power supply for increased reliability and performance
The RMX 4050a provides improved thermal performance yielding higher continuous power in 2 ohm stereo or 4 ohm bridged applications.
Compact size — up to 2500 watts in 2 rack spaces or 5000 watts in 3 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
Balanced 1/4” (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 to monitor performance
Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers
