hello , i have a relay inside a chassis. The relay is controlled by a switch and 5v dc regulated supply. And the relay is used to turn on and off balanced AC audio.
i would like the chassis project box to be connected to the shield of the audio, so to protect the audio signal whist inside the chassis from noise.
but I wonder should i connect the dc ground that controls the relay to ground plane of the pcb so that all grounds/shields are connected together or should i keep them separate?
thanks for your help.
