The QSC RMX 4050HD is one of two heavy-duty models in the RMX Series, engineered to work as hard into 2-ohm loads as most competing amplifiers will at 4 ohms. Its three-tier Class H design is extremely efficient at real-world power levels, wasting less AC current and putting more available current into useful audio power. The 4050HD delivers 800 watts per channel into 8 ohms, 1300 watts into 4 ohms and 1600 watts into 2 ohms in stereo, or 2600 watts bridged into 8 ohms and 4000 watts into 4 ohms. Improved thermal performance yields higher continuous power in 2-ohm stereo and 4-ohm bridged applications, while a dual-mono, high-current power supply with toroidal transformers boosts reliability. Connectivity covers balanced 1/4-inch TRS, XLR and barrier strip inputs plus touch-proof binding post and Neutrik Speakon outputs. Independent user-defeatable clip limiters, selectable 30 Hz or 50 Hz low-frequency filters and complete protection circuitry safeguard amp and speakers alike. All this fits a 3RU chassis only sixteen inches deep, ideal for touring and installation racks in Kenya.
