QSC GX3 Stereo Power Amp

| Review By: Chris LaPlante | 9 months, 3 weeks ago

2 people out of 2 found this review helpful

Features:

The features are what you expect to find on most modern amps. Haven't had a need for the built in 100 Hz crossover, but when I decide to buy a separate sub I will definitely use it. The one feature I would add is handles on the front for easier mounting.

Quality:

Built tough, and capable of handling tour use. Love the optional rear rack mounts. The sound quality is crisp and clean. I use the GX3 with a couple of Bose 802's and I just love the sound that it puts out.

Value:

Just the right amount of power for my needs without having to sell a kidney to get it. Great value.

Overall:

I think the amp is perfect for a medium to large venue/audience setting. It's not too heavy and doesn't take up a lot of space.

I would definitely recommend this amp to anyone who needs some power for their speakers and who is on a budget.

SOLD ON QSC!

| Review By: The guitar guy | 1 year, 2 weeks ago

The sound quality it there with this amp.      I'm sold now on QSC and will buy only their amps for any future needs.

I had some extra rack equipment sitting around so I put together a stereo system for my party room.      This amp was perfect.      I'm runing a mono signal and using the bi-amp function to power two PV118 cabs and two Peavey 15 inch monitor speakers.      For pre-recorded music, it's a great set-up.      The party room shakes when I turn up the lows.      I'm very happy with the quality of this amp.      The price was great for what you get.

Well built.

425 watts per side at 4 ohms with bi-amp 100 hz x-over for this price!
