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 …

I need to switch stereo audio input (i.e. Ipod/Iphone level signal) from source "A" to another "B". The vehicle switch is effectively an SPST. So, to switch the two channels, I need to use one DPDT or two SPDT relays to swap the two channels. It would be a mechanically robust mobile solution...

A relay in an audio path is going to cause a "pop" under two conditions: If there's a voltage across it at the moment it closes. If there's a current flowing through it at the moment it opens. There's no way around this; if you can't avoid these conditions, then a relay may not be the correct solution for your application.

I'm trying to understand/use relays for audio switching, and i don't know how to choose a relay. I know that relay circuits must be driven from a separate psu to avoid switch noise in audio signals. The NEC EA2 series is the one I like. They have been used in all kinds of applications. You can get it any coil voltage from 3-24V.

Audio signals (not power) can be switched with miniature signal relays, or reed-relays. Typically a signal. relay has a smaller ac voltage rating for the contacts that a typical power relay.

I would use DPDT relays. (If you’re switching unbalanced audio, or a 4PDT relay if you’re switching balanced audio). The relay will be switching both the signal and the audio GND lines, and in no way will connect to your digital circuit’s GND. The relays will be controlled via logic level mosfets/or transistors, which turns on/off the individual relays.
