Flotsam71 Posted July 9, 2016 Share Posted July 9, 2016 Just have a crazy question for everyone.....When my helix is connected to my PC via USB, I hear digital noise....like static from mouse movements and mouse button clicking. Even if helix is off...It comes through my amp. Could this just be a ground loop thing...all for mentioned items are on the same circuit. No other sound comes through...such as music because it is turned off from PC. Not using helix as a "speaker". Thanks so much guys...Love this forum....and the helix!!!

BigRalphN Posted July 9, 2016 Share Posted July 9, 2016 Try your PC on a seperate outlet. Quote Link to comment Share on other sites More sharing options...
mileskb Posted July 9, 2016 Share Posted July 9, 2016 You might try re-locating the USB cable.. Just a different route... I have had this issue and moving the cables around ensuring USB wasn't crossing power or audio usually got rid of it. Quote Link to comment Share on other sites More sharing options...
Dshow Posted July 9, 2016 Share Posted July 9, 2016 I have this too but on mine the pickups are picking up the noise. If I turn away from the screen the nois gets away or at least not that loud. Quote Link to comment Share on other sites More sharing options...
malhavok Posted July 9, 2016 Share Posted July 9, 2016 Yeah, if you are sitting near your computer while playing it is most likely the guitar pickups. Try turning your guitar volume knob off and see if the noise goes away. Quote Link to comment Share on other sites More sharing options...
Charlie_Watt Posted July 9, 2016 Share Posted July 9, 2016 USB creates a ground loop. Using the XLR outputs really helps this. Quote Link to comment Share on other sites More sharing options...
spikey Posted July 10, 2016 Share Posted July 10, 2016 If Helix is off and you still get noise, unplug its USB cable from the computer side and see if its still there. If it is then its not the Helix USB cable. Quote Link to comment Share on other sites More sharing options...
stephane_dupont Posted July 10, 2016 Share Posted July 10, 2016 For my live setup (which is a Helix being used as a multi FX and sent into two amps, and also being used to send MIDI signals to a computer that handle various things), I had to remove the USB connection between the Helix and the computer and use a MIDI cable instead. If not, computer was making noise in the amps... (Using an outlet without ground helped a little, but just a little, was not enough.)

malhavok Posted July 10, 2016 Share Posted July 10, 2016 If computer is making noise through your amps you should be able to fix that by telling your computer to stop outputting audio to that USB device. In your computer settings tell it to ignore the Helix as soundcard. Windows is especially bad at this but it can happen on OSX as well.

That being said, for MIDI only, MIDI cables are way more easier (and stable) to use anyway... Quote Link to comment Share on other sites More sharing options...
