Lightweight Power Amp at a Nice Price!

Not all power amps are created equal. And when you're counting on your power amp to perform, you want to trust it. Power amps are not the kind of gear you want to "cross your fingers" about. And that's exactly why you go with QSC. These guys have been making some of the world's best, most dependable power amps - and they've been making them for a long time now. So you know that when you put the QSC GX3 to work, you're not just getting a power amp... you're getting part of a power amp legacy. And that's important.

So let's dig into the nitty gritty and tell the story here. The QSC GX3 is a 425W (4 ohms, stereo) power amplifier that's optimized for maximum real-world headroom. It's got XLR, TRS, and phono input connectors so it'll fit into any system. Plus GuardRail automatically protects the amplifier and loudspeakers, in the event of temperature rise or overdrive - all without making your show go dark. So already, we've got three bonuses: the power you need, the flexibility you need, and the protection you need. Not a bad combination. And with a light weight (under 30 lbs.) plus detented gain controls so you can precisely set it... you've got a winner with the QSC GX3.
