QSC RMX4050A 3RU 2-Channel Power Amplifier (1300W @ 4 ohms)
The RMXa Series amplifiers from QSC offer true professional-quality performance at an affordable price. The RMX4050A takes up 3-rackspaces and includes a comprehensive set of features including XLR and 1/4" balanced inputs, Speakon and binding post outposts for convenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.
The RMX 4050a is a "heavy duty" model designed to work as hard into 2ohm loads as most competing amplifiers will at 4 ohms. It features a three-tier, Class H design that is extremely efficient at real world power levels. Less AC current is wasted and more available current goes into producing useful audio power. 120 volt versions of the RMX4050a accomplish all this with a standard 15 amp plug.
Features:
- Professional quality performance—incorporates road-proven QSC designs
- Operates on a standard 15 amp plug (120V)
- Features 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.
- 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
- 3-year warranty plus optional 3-year extended service contract
