Muting Circuits For Audio

https://www.sound-au.com/articles/muting.html

The relay is wired so that the normally closed contacts simply short the signal to earth (ground). Until the relay is activated, the signal is muted, and because the contact resistance is typically only a few milliohms, there's no need to add resistance to the circuit that provides the audio signal (typically an opamp).
