QSC GX3 - Power Amplifier

GX Series amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget. The hallmarks of the QSC brand - professional audio quality, meticulous engineering, precision manufacturing and long-term reliability - are all intrinsic to GX. Add contemporary styling, multiple input/output options, light weight, and advanced protection circuitry, and the GX Series clearly represents real value - something everyone can use.

Features:

  • Power levels matched to the most popular speakers used by entertainers
  • Optimized for maximum real-world headroom into 4- and 8-ohm speaker systems
  • Inputs: XLR, 1/4-inch TRS and phono input connectors for compatibility with any source
  • Outputs: Speakon® combo accepts 1/4-inch (TS) plugs or Speakon 2- and 4-pole plugs (connects 2 poles only). Binding posts support all other speaker wiring systems
  • Minimum depth chassis (10.1-inch / 257 mm) fits in compact, inexpensive effects racks
  • Lightweight - GX3 and GX5 less than 26 lb (12.5 kg). GX7 only 15.5 lb (7 kg)*
  • Detented gain controls for precise setting and matching of sensitivity
  • GuardRail™ automatically protects the amplifier and loudspeakers from damage due to temperature rise or overdrive without shutting down the show
  • Front panel LEDs monitor power, signal, and clipping
  • Subwoofer/satellite crossover built-in
