Power Amp Amplifier QSC GX3; 2 Channels 425 Watts for speakers, monitors
For sale is one QSC GX3 power amp. Used but works perfectly. Great for bands or DJs. We used it to power our monitors, while the PA powered the main speakers. But you can use this to power any unpowered speaker you want. Tons of power, 2 channels, great tone. QSC is very respected in the power amp business. $170.00, sorry no trades please.
I've seen this particular model running over $250 for used. I think there's one on ebay right now for $150, but it says it needs repairs.

Here's info from the company:
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.
