The RMXa Series amplifiers from QSC offer true professional-quality performance at an affordable price. RMXa amplifiers include 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.

  • 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” (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
