Can not eliminate dry signal coming out of XLR output in Helix Posted July 15, 2019 Hmmm. I was under the impression that turning that bypassing the amp would give you 0 sound, so i figured i was doing something very wrong. But what you're saying makes more sense. If I take the amps and activate them, then turn the volume on them completely down I get no sound. So I guess I'm just hearing things? Maybe I just need to tweak the sounds out a bit more. Thank You!
