BlueViolince Posted December 15, 2015 Share Posted December 15, 2015 HD500, with a Source Audio Hot Hand 3 controller. I've been using this setup for at least a year now, but I only just noticed a bit of crackle when playing through headphones. I unplugged the patch cord from the HH3, but left it powered on, and the sound disappeared. Also unplugged power from the HH3, and left it plugged into exp2. No noise. All power cords are far removed from each other, and I did use new patch cords, instrument cables for the exp2 connection. No other variables got rid of the crackle besides powering down and/or removing the HH3. Is anyone else experience noise when using a powered expression pedal?

BlueViolince Posted December 15, 2015 Author Share Posted December 15, 2015 No noise through the 1/4" output into my Power Engine. I generally use the 2 XLRs when playing at church, so I will have to test that out tomorrow. Quote Link to comment Share on other sites More sharing options...
pfsmith0 Posted December 15, 2015 Share Posted December 15, 2015 If the base unit can operate from batteries, try not using the power cord and see if the crackle stays there. Quote Link to comment Share on other sites More sharing options...
BlueViolince Posted December 15, 2015 Author Share Posted December 15, 2015 It doesn't have a battery option. It does run on low amp 5.0vdc, so maybe a filtered USB power supply wired to the right barrel plug would do the trick. Quote Link to comment Share on other sites More sharing options...
