Read that it's recommended to run power cables and audio cables perpendicular to eachother on a pedalboard to prevent interference and noise. Is there truth to this? I read somewhere else it only matters if using AC power and not DC. I ask because I'm racking my pedals and will have a remote board with a Wah and whammy. I'd like to build a Loom that has send and return audio cables for the Wah and whammy back to the rack, a midi cable and a power cable so that I can power a Voodoo Labs ISO5 on the remote board from the Furman in the Rack. Wondering if there might be any issues having a power extension cable like this along with audio cables in a loom? I'll also have an XLR/7 pin midi cable in there to phantom power my Midi Controller so there will be that line of power as well in the loom. Anything to be concerned about? Should I separate the audio and the midi/power cables into 2 looms or will they be fine together? Lastly, what's up with power con connectors? To make setup easier I would love to have the entire loom connect to a rack patchbay on the back so all audio sends and returns, midi and power is easily accessible for setup and breakdown. Will a powercon connection work to connect an outlet of the Furman to the rack patchbay, so that on the power cable in the loom, I can plug a powercon connector to the back instead of having to plug it directly into the Furman?
