wilkinsi Posted March 22, 2017 Share Posted March 22, 2017 Excuse the resurrection. If I were to briefly switch on phantom power of a mic preamp whilst the Helix (floorboard) XLR outputs are already connected to it, would there still be damage? Is the end result a dead output, a dead Helix, or permanent poor sound quality, even after phantom power was turned off? Quote Link to comment Share on other sites More sharing options...
