How do most of you wire up your volume pots? Do you use shielded wire? And if so do you run the shield to ground with its own wire from the input end or do you run the signal return on the shield and connect it at both ends?
I am using a pcb with a big ground plane on it so I am running all my grounds to this like a star ground. Should I run the shield as a signal return and use it to carry the ground from the rca to the pot. then from the pot to the pcb input?
Or run the rca ground straight to the pcb and skip the pot, running a wire from pot ground to the pcb?
And do you connect the shields to ground with a seperate wire or do you use them as a signal return? I have seen it both ways.

A pot mounted inside a steel chassies needs no screened wires. The steel
chassies will screen from outside hum and noise.

So long as its kept away from transformers, mains or low impedance signals the wires should be fine.
