    Comments about QSC GXD 8 Professional Power Amplifier:

    This amplifier is powerful and loaded with features. The on board DSP is nice and easy to use. Plus it saves rack space. The weight is the best part about this amplifier. Class D has changed the ways of pro audio for the better.

          After using different power amps this qsc gxd8 took a little time for me to get use to.So I took time to check it out and set up for my subs-----using the limiter delay and crossover and eq---The live sound of my kick --is fantastic and more than enough headroom --ps I run sound from stage for my band for 20 years this is the best investment on pa gear i ever made.
