Question

Hey Everyone, I have got my Line 6 Pod Go hooked up to a pair of PreSonus Eris 4.5 studio monitors, and I have been using this setup for about a month. Recently it started to really bug me that when I play on some presets that I have made, after I have played for ~3-4 minutes, the speakers will start to crackle when I hold a note. I have recorded the sound and put it on soundcloud, if you would like to listen here is the link (You can faintly hear the crackle at the end of the recording, it sounds worse in person): https://soundcloud.app.goo.gl/eGpZ7

I have been trying hard to find a way to fix it, have changed all of my leads, moved to different power supplies etc. to test if it was a grounding issue. No matter what I try, the crackle always comes back. Is it because the signal out of the Pod Go is too hot for the speakers in some of my higher gain presets? Or am I overheating my speakers? Would putting a cheap audio interface between the Pod Go and the monitors would help? I'm really hoping someone has an answer for me, thanks in advance.

Hi,
 

I'm having the exact same issue - Pod Go plugged into a pair of E4.5's and getting crackling and popping randomly while playing.

Initially I tried playing around with noise gating but that didn't seem to fix anything. From looking around the web it seems like there may be power being sent back up the loop to the guitar. This would seem to make sense as I'm finding is that volume and tone knobs on any guitar plugged in to the Pod Go while hooked up to the Eris speakers become more or less active - that is they behave as though they're an exposed jack lead and react to touch - instantly stopping any crackling sound completely.

This isn't a fault with my cables or the guitars as this behaviour does not repeat when I use headphones instead of the speakers or when I plug the guitar into my 120w amplifier. The issues appears to very definitely be a small amount of active current being routed back up my guitar input. I don't know what the solution is?
