Relays for Switching Audio Signals
http://www.geofex.com/Article_Folders/relays/relays_for_switching_audio_signa.htm
Relays are some of the oldest switching parts available, butthey are misunderstood by many audio hackers. Here's a run down on the basicsand how to apply them. Relays are electro-magnetically activated switches. Literally,there is an electromagnet inside the relay, and energizing that electromagnetcauses the switch to change position by pulling the movable …

Is it possible to turn an audio signal ON/OFF using a ...
https://electronics.stackexchange.com/questions/110750/is-it-possible-to-turn-an-audio-signal-on-off-using-a-solid-state-relay
There are solid state relays designed primarily for audio, which is what you'll want to use. There are in general some things you'll want to be aware of when using a solid-state relay. First, you'll want to make sure the on resistance is compatible with your load. For example, if you are trying to drive a low impedance like a speaker, you cannot use a SSR which has high on-impedance (for …
