What are the guidelines for your power voltage path in your audio project? Answered

Are you supposed to avoid crossing it over your audio signal, or parallel to it, or across or parallel to your ground wire?  And if the enclosure is grounded, should you avoid running it against the enclosure?


The general guideline is to run the signal path at 90 degrees to the power supply path. This doesn't mean you can never run them parallel to each other, but you should strive to minimize the number of times that happens. Also try to minimize the number of times the signal path passes over/under the power path. If anything, let it cross over the ground path.

As I said, this is just the general rule.
