The GX7 amplifier is ideal for professional entertainer who require maximum performance and portability on a limited budget. The hallmarks of the QSC brand professional audio quality, precision manufacturing and long-term reliability.

Description

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.

GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Typically, loudspeaker manufacturers recommend an amplifier with power output equal to the speaker’s “Program (Music) Power” rating or two times (2 x) the “Continuous (RMS) Power” rating.

The GX7 outputs 725 watts into an 8 ohm load. Owners of popular 4 ohm loudspeakers (such as dual-woofer, two-way models) will find the 700 watt (4 ohm) power, the GX7 1000 watts will very capably power many of today’s popular subwoofers or two typical 8 ohm speakers per channel.

The GX7 adds the road-proven PowerLight supply to the Class H output section, for more overall output power and additional weight savings. The result is one of the highest power-to-weight ratios in the industry. A low-noise variable-speed fan with rear-to-front airflow keeps amplifiers and racks cool.

As always, GX Series amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life.

Features
  • Power levels matched to the most popular speakers used by entertainers.
  • Optimized for maximum real-world headroom into 4 ohm 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-pole 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.
  • 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.
