QSC GX7 power amplifier


I was using this for an event some time last year. I remember that the event was a success and the sound was loud and punchy. It was partly credited to this lovely QSC GX7 amplifier that were powering the two main speakers. Now in the past, I have never been an advocate, of sorts, to these QSC GX series amplifiers but I am a convert now. I have installed these amplifiers in a couple of places and I can safely say that these amplifiers can really push their power well and handle their jobs with ease. This GX7 for instance. Both channels driven, it can put out 725 watts of power into 8 ohms. Into 4 ohms, it can put out 1000 watts. Not too bad really. As for connectors, there are XLR, 1/4″ TRS for balanced connections, and phono for unbalanced connections. Features-wise? Here you go:

  • 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

I am still used to the Yamaha amplifiers that I have used for many installs and even Yamaha have come out with some good ones recently. But given the fact that these from QSC are really good, it has been making me think twice about which amp I should be getting.
