  • 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 (120V)
  • 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
  • 3-year warranty plus optional 3-year extended service contract
