I am intending to make some short (<30cm) unbalanced audio cables to interconnect devices on a musical instrument pedal board.
As a matter of convenience, I was thinking of using some Belden 9451 three-conductor cable for this because I have a lot of it. It has an insulated twisted pair (red & black) inside a shield wrap. (I wouldn't call it a braid)
Probably overthinking this, but I'm curious if there is a "best practice" for using three-conductor cable for an unbalanced audio signal - some immediate options being;
1 - twist both inner conductors together for signal, use shield for ground
2 - use one inner (red) for signal, twist black and shield together for ground
3 - use inner twisted pair exclusively..red for signal, black for ground...shield unconnected
or is it all the same when it comes to such short cable lengths?
