Description
The RMXa Series amplifiers offer true professional-quality performance at an affordable price. With 1400 W/CH into 4 ohms and 2000 W/CH into 2 ohms all in a chassis that is less than 16 deep the RMX4050a is perfectly suited for performing musicians and mobile entertainers.
Features:
- Professional quality performance-incorporates road-proven QSC designs
- The 4000 watt RMX 4050a operates on a standard 15 amp plug (120V)
- Both the RMX 4050a and RMX 5050a feature 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.
- Compact size - up to 2500 watts in 2 rack spaces or 5000 watts in 3 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
- 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
