Features:

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 (120 V)
Both the RMX4050a and the RMX5050a 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

The RMXa Series amplifiers from QSC offer true professional-quality performance at an affordable price. Feature a compact chassis less than 16-in deep. RMXa amplifiers include a comprehensive set of features including XLR and 1/4-in balanced inputs, Speakon® and binding post outposts forconvenient connectivity. User-defeatable clip limiters and selectable low-frequency filters optimize sonic performance.
