Provides 1,000W at 4 ohms in a lightweight design with special protection technology.
The GX7 professional power amplifier continues in the tradition of QSC's top-selling GX Series professional power amplifiers by offering an attractive combination of power, fidelity, configurability, long-term reliability, and overall value.
At the heart of the GX7 is an all-new, advanced power supply based on the road-proven PowerLight Series technology. The result is a more overall power output in a lightweight casing compared to previous GX models—without any sacrifice in audio quality.
At 1000W per channel at 4 ohms, the GX7 provides more than ample power to connect up to four 500W 15" 2-way speakers or two 1000W subwoofers at a time. This will help to keep your overall system cost down while still maintaining maximum performance levels. The 8 ohm output is 725 watts per channel which yields considerable headroom and increased dynamic range for today's popular loudspeakers.
Features
- Road-proven PowerLight Series amplifier technology
- GuardRail (also found in K and KW Series loudspeakers) protects both the amp and speakers from damaging clipping and overload without audible pumping or distortion
- Subwoofer/Satellite crossover built-in
- Inputs: XLR, 1/4" TRS, and phono input connectors for compatibility with any source
- Minimum depth chassis (10.1"/257mm) fits in compact, inexpensive effects racks
- 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
- Front panel LEDs monitor Power, Signal, and Clipping

Comments about QSC GX7 Stereo Power Amplifier:
I also own the QSC GX5 that I power my JBL 15's with horns.
This GX7 will power my JBL 18 subs.
My experience with QSC amps shows that they're powerful with plenty of overhead, silent and the new GX7 is super light weight.
It's a winner in all areas of PA amplification!

Comments about QSC GX7 Stereo Power Amplifier:
I bought a GX7 from MF to power a pair of JBL PRX425 speakers. Powerful, clean sound from the QSC even when the red clip LEDs are occasionally blinking. Some reviewers complain that the cooling fan is a little noisy. But in my experience, it only kicks into high speed cooling when you're pushing the amp hard and then the music is so loud, I don't see how you could possibly hear the cooling fan. It's a very basic amp without all the programmable settings that many power amps offer - but that's exactly what I want. Simple, straightfoward, powerful - with fewer bells and whistles to tear up. It's the best power amp buy out there for an amp that truly outputs what it is rated at!
Comments about QSC GX7 Stereo Power Amplifier:
I run 2 sets of Jbl Mrx series 15in 2 way speakers with my new GX7 amp and the sound is really great. I use to run 2 GX5 amps for the same 2 sets of speakers and at 17 pounds it really makes a weight difference, and the GX7 works just great. I advise anyone that is going to put together a PA system to take the time to check out the GX series amps, with a 5year warranty. You will be very happy with the GX series line.
