Maximum performance and portability with very flexible I/O.

The QSC GX5 stereo power amplifier provides 700W of power in an efficient, rackmountable design. Perfect for entertainers and presenters who require maximum performance and portability, the GX5 power amp utilizes QSC's Class H amplifier technology to produce high power output from a compact, lightweight 1U chassis.

700W for Impressive Volume and Headroom

With 700W of power per channel into 4 ohms, the GX5 drives professional loudspeakers to provide impressive volume and dynamics for live performances and presentations. The high power output offers substantial headroom to reproduce transient peaks without distortion for a clean, articulate sound.

Class-H Amplifier Design for Efficient Power

QSC's Class-H amplifier design allows the GX5 to generate high power output from a space-efficient 1U rackmount chassis. Class-H operation dynamically switches the amplifier's power supply rails to continuously optimize efficiency at the amplifier's current operating level. This significantly reduces power consumption and heat generation compared to conventional amplifiers.

Rackmountable 1U Chassis for Professional Installations

The GX5 Stereo Power Amplifier is housed in a durable 1U rackmount chassis for simplified installation in professional AV racks. Rear-mounted input, output and power connections provide convenient access to all cabling. Thermal efficiency allows multiple GX5 amplifiers to be mounted adjacent to each other in equipment racks with no risk of overheating.


  • 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
  • Lightweight: less than 26 lb. (12.5 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
