        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.
