The QSC GXD 8 is a seriously powerful little amp – it's a great choice for bands needing a compact, high-output solution for smaller to mid-sized venues or portable setups. The built-in DSP makes it a breeze to dial in your sound, and the overall build quality is very QSC. It's a workhorse that won’t quit.

Frequently Asked Questions
It's a streamlined solution, offering essential EQ, filtering, and delay – not as deep as a dedicated processor, but sufficient for most live sound applications.
The Hi-peak rating represents short bursts of power; sustained output will be closer to the RMS wattage at a given impedance.
Speakers with a clean, efficient design will perform best, as the amp’s power delivery benefits from a well-matched transducer.
