Signal and power cable proximity

[fretlessman71]

I have a VERY small studio area. I try to keep things as neat and out of the way as possible. Should I be concerned about where my bass cable goes and what it gets too close to? Wrapping it around and behind certain things (interface, router, computer) would help keep the cable from dangling over the keyboard and such, but should I be concerned about picking up extra noise?

(Please skip the "just try it and see" posts. I plan to do just that, but I have limited mobility and energy and try to use both as judiciously as possible.)

if you are using a good shielded cable, you probably won't notice much of a difference. always a best practice to keep your instrument cables away from your power cables and anything that emits EMF whenever possible.

Do the best you can within practical limits to avoid running cables carrying analog audio signals (instrument, mic, patch) near powered cables, and if you must, have them cross at 90 degree angles rather than run parallel to one another.

I've never had a problem routing audio and power cables next to each other. It's been done for years in the FOH world as a snake and power are run out to the board. And I never a problem worrying about running an audio cable next to a wall where there might be several line circuits in the wall.

Where I've seen problems is from running the audio cables next to older or cheap class-d amp speaker cables. Old class-d before engineers worked it out may have crap filters. And some older monitors used CFLs for backlights. Lot of this has/was worked out when FCC was actually effective agency.

In any case to just re-route the cable. Learn about ground loops. Avoid power conditioners as they do nothing.

My pedalboard setup has a 30-foot loom that runs mains power to pedals' power supply, instrument cable return from pedals to amp, and a XLR cable from pedalboard DI to amp rack in one bundle (inside a nylon webbed tube). No problems whatsoever.
