    QSC RMX4050HD Power Amplifier Product Description

    QSC's RMX 4050HD power amplifier represents the state of the art in professional-quality performance at an affordable price. Perfectly suited for a wide range of sound reinforcement applications including professional touring, performing musicians, and mobile DJs, the RMX4050HD is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven reliability.

    Like its smaller sibling (the RMX 1850HD), the QSC RMX 4050HD is 1 of 2 RMX "Heavy Duty" models designed to work as hard into 2-ohm loads as most competing amplifiers will at 4-ohms. With a 3-tier, Class H design, the RMX4050HD is extremely efficient at real world power levels. Less AC current is wasted and more goes into producing useful audio power. The QSC RMX 4050HD accomplishes all this with a standard 15-Amp plug.

    Like all RMX amps, the QSC RMX 4050HD features balanced 1/4 in. TRS, XLR and barrier strip inputs, binding posts and Neutrik Speakon outputs, front-mounted gain controls, plus signal and clip LED indicators to monitor performance.

    The QSC RMX 4050HD provides improved thermal performance that gives you higher continuous power in 2-ohms stereo or 4-ohms bridged applications

    Features:

    - Dual mono, high current power supply for increased reliability and performance
    - 3RU chassis only 16 in. deep
    - Professional quality performance--incorporates road-proven QSC designs
    - 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 in. (6.3 mm) TRS, XLR, and barrier strip inputs
    - Binding post and Neutrik Speakon outputs
    - Front mounted gain controls for easy access
    - Signal and Clip LED indicators to monitor performance
    - 3-year warranty
