Excerpt: Bought this to replace an old amp with a bad channel. Used for overflow speakers in our church lobby ceiling. Inputs and outputs were totally compatible with our system's existing wiring, making it a simple hook-up. It worked perfectly right out of the box.
Quality and affordability in an amp that performs night after night!

Summary: The QSC GX-3 amplifier is a clean and powerful amp that offers legendary QSC quality on a budget. I've been using the GX-3 as a 2-channel monitor amp for live gigs running 4-5hrs per night. I've also employed its big brother (the GX-5) as a mains amp in the same setup.
Summary: This is a great amp for a high-fidelity, power-hungry system, and the 6-yr warranty caps it off! FYI I am an audio/HT enthusiast, and will spend money on good picture/sound, but always looking for the best deal. It is driving Magnepan 1.7 speakers, which are quite power-hungry.
Excerpt: This is a great amp! I am using it in a youth room at church. Two main speakers are hooked up to it and it works great. Barely have it turned up and it fills the room with sound. I would agree with others about the humming sound.
