QSC GX3 Power Amplifier
GX3
Usually shipped within 2-3 working days
The GX3 uses the latest evolution of the QSC Grounded Collector output system, for optimum cooling of the critical power transistors.
A true Class B biasing system combines maximum thermal efficiency with excellent audio performance ideal for speakers in the 300 W range.
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" TRS and phono input connectors for compatibility with any source
- Outputs: Speakon® combo accepts 1/4" (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" / 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
* 230V 16.5 lb (7.5 kg)
