Description

The QSC GX5 power amplifier features power levels matched to the most popular speakers used by entertainers, and optimized for maximum real-world headroom into 4- and 8-ohm speaker systems.

At just 12.6 kg, the QSC GX5 power amplifier is light enough to cart around – but we’re seeing most of these get picked up once, plonked into a fixed installation and left to do their thing. They’re loaded up with all the usual protection features you’d expect these days from an amplifier: Short circuit, open circuit, thermal, RF protection, and load protected against DC faults. Plenty of connectivity with inputs via 2 x XLR, balanced 1/4″ and also RCA.

QSC GX Series – 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.

Output power:

  • 8 ohms / 1 kHz (both channels driven): 500W
  • 8 ohms / 1 kHz (single channel driven): 600W
  • 4 ohms / 1 kHz (both channels driven): 700W
  • 4 ohms / 1 kHz (single channel driven): 850W

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-inch TRS and phono input connectors for compatibility with any source
