 Product Description

QSC RMX 2450A Power Amplifier

 

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
