The QSC GX3 425-watt power amplifier gives your speakers the power they need while giving you the efficiency and protective features you want for easy operation and peace of mind. The GX3 uses advanced components for both light weight and reliability. Its Guardrail protection allows delivery of peak power while preventing overloads. It's equipped with a crossover switch, so adding a subwoofer to your system is a snap. Optimized for 4- and 8-ohm speakers, this amp also fits perfectly into popular racks, and its lightweight design (less than 30 lbs.) makes the GX3 incredibly easy to transport.

At just 12.1 kg, the GX3 is light enough to cart around - but we're seeing most of these get picked up once, plonked into a fixed installation and left to do their thing. They're loaded up with all the usual protection features you'd expect these days from an amplifier: Short circuit, open circuit, thermal, RF protection, and load protected against DC faults. Plenty of connectivity with inputs via 2 x XLR, balanced 1/4" and also RCA.

QSC GX Series - Professional audio quality, meticulous engineering, precision manufacturing and long-term reliability - are all intrinsic to GX. Add contemporary styling, multiple input/output options, light weight, and advanced protection circuitry, and the GX Series clearly represents real value - something everyone can use.

Output power:

  • 8 ohms / 1 kHz (both channels driven): 300W
  • 8 ohms / 1 kHz (single channel driven): 350W
  • 4 ohms / 1 kHz (both channels driven): 425W
  • 4 ohms / 1 kHz (single channel driven): 500W

Suction cups aren’t the best
Color: Black+Smiley Face
The suction cups don’t hold and my smiley sponge isn’t snug on the post so it sometimes falls off.

Sticks and stays in place!!
Color: Black+Smiley Face
Love love loveeee this! Took me a while to find one that actually sticks and stays in place. I've had mine for a few months now. Looks just like the photos & comes with the suction cups and an adhesive strip if you want a firmer hold. The suction cups work just fine. Would recommend 👍🏾😁

Meets My Expectation
Color: Pine, Color: Pine
Meets my expectation. I ordered these to put on my living room wall. When I opened the box they were neatly wrapped and packaged. Super easy to put together and install. I love the rod bracket that mounts onto the wall making it easy to slide the rods into the holes on the back of the shelf. Very sturdy and holds my little decors and look nice on the wall.
