Couldn't ask for a better amp

SO LIGHTWEIGHT compared to the old workhorse QSC amps that we all know and love, but hate to lug around. Clean sound, no hum when music's not playing, great power, great price.

Plenty of Clean, No-Frills Power

Tons of cool, clean power, and quiet between songs. What more could you ask for? How I use it: I use this amp to drive (2) 8ohm main speakers, after an 80Hz high-pass crossover. I have never attempted to use the GX7 for subs or a full-range signal. I have also never used the on-board crossover switch. So, basically, your mileage may vary depending on use. But for my purposes, this thing is perfect. Couldn't be happier.

Awesome clean power!

Blown away! QSC has always been my go to amp for over 25 years. This QSC GX7 rocks! Thank you Sweetwater!

Good solid amp!

I own two gx3 amps and I was shocked at the quality and cleanness of the power output. I now have two pa cabs with 2 15 inch speakers and horn. 4 ohm load and with the gx7 1000 watts per side. This should be enough for small to medium venues. QVC makes a fine product with excellent specs. I trust QVC and can't wait to try it out at the next small gig. With past experience I give this 5 stars. I will write another review if this does not perform as expected but I seriously don't expect to change my opinion.

More power is better

I was inviited a while back to tour the manufacturing facilities of QSC in Southern California - that's right made in the U.S. - right down to the circuit boards and cases, but I didn't need an amp at the time. When my monitor amp blew up, I decided to re-locate my old main amp to power the monitors and purchase the QSC GX7 to use as our new main amp. This increased substantially the power to our mains. Because we sit behind the mains, we're not as aware of how they sound as our audience is. Within 10 days of installing the QSC, a half dozen people came up to us and wanted to know what we had done. We sounded so much better. Forget our opinion of the amp - our audience loves it. I would have never guessed it made that much of a difference.
