• 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
