garbanzo Posted June 9, 2018 Share Posted June 9, 2018 My Helix rack works fine as far as I can tell. However when I connect to my pc via usb I get a low grade hummmmmm. I am updated to 2.54 software and am in an environment without florescent lighting, or ever other equipment other than pc, Helix and my amp GK MB200. I am presently in an out building with no other electrical things connected to the circuit, and I have the same problem at home where there are other electrical things connected. So the problem is the same in both settings. Does anyone have a suggestion to offer, or have similar experience?
