loopinit Posted October 7, 2017 Share Posted October 7, 2017 Help! I was practicing my setlist and walked away for five minutes. When I came back and rocked my expression pedal back up, my guitar signal was barely audible, and there is a HUGE amount of white noise like a ground loop within Helix. I reset the firmware and it's in the stock presets too. I restored my presets and IRs, and it's still there. I changed my guitar cable, it's still there. I also changed from XLR output into my JBL PRX monitor, to my Yamaha HS5 studio monitors. It's still there. It's affecting the guitar signal coming from the 1/4" and XLR outputs. I route my audio from the computer into Helix and back out through the 1/4" outputs, but the digital audio isn't affected. Quote Link to comment Share on other sites More sharing options...
loopinit Posted October 7, 2017 Author Share Posted October 7, 2017 I used my Telecaster and Gibson, and it is the same with both. I tried the auxilliary input and it's the same problem using a different input. Quote Link to comment Share on other sites More sharing options...
loopinit Posted October 7, 2017 Author Share Posted October 7, 2017 So weird. All of a suddn it works again. Maybe it was a low voltage brown out. Quote Link to comment Share on other sites More sharing options...
jbuhajla Posted October 8, 2017 Share Posted October 8, 2017 Which Helix type are you using? I think someone else experienced something similar and posted about it a week or two ago. Quote Link to comment Share on other sites More sharing options...
tagmusenmagnus1 Posted October 8, 2017 Share Posted October 8, 2017 What are you hooked up to ? This sounds like the behavior of helix when the outputs are connected to a mixer, that sends out phantompower.. Quote Link to comment Share on other sites More sharing options...
