QSC RMX 4050a

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). RMX4050a 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.
