Hi guys, hoping you can help me! I've had my PBC10 board for a while now and it works great, but I'm trying to reduce the noise level when I'm not playing. I'm pretty sure it's a ground loop - is there any way I can test for this, and where would I need to put isolation boxes in my chain to remove it if it is a ground loop?
I'm not with the board right now, but I think these are the chains.
Guitar>wireless transmitter>wah>volume>PBC10 - split insert cable from out 6 - 7 to two amps (JVM410H and Victory V100)
then in loops 7 - 10 I'm running all stereo pedals other than an Eventide Rose, but I'm using the ring disconnect cables to convert that to stereo. A send and return comes from both amps into these pedals in stereo. I'm also running a TRS cable for amp switching to the Victory and a MIDI cable to the JVM for the same reason. Mono/Stereo buttons on the PBC are set to the right settings (I think) and I'm using the ISO B switch too.
Happy to make a diagram if that helps! When I'm not playing, especially with higher gain, there's a loud hum coming from the Victory which I'm assuming is a ground loop. Looking to test that then grab an EBTech hum eliminator (or two) to fix the problem. How would I test for ground loops, and where would I need to put the hum eliminator(s) in my chain for them to work?
Sorry for all the questions, I'm pretty new to all this stuff! Thank you.
