The relay is always on, the relay will not be disconnected and flashed, and the audio trigger signal After stopping, the timing starts from the new time, and the delay time reaches the relay disconnection; 5, there is a power indicator (red LED) and switch trigger timing indicator (green LED); 6, with timing potentiometer adjustment time, product design is adjustable from 1 to 180 …
Using relays for audio signal switching? | DiyMobileAudio ...

It would be a mechanically robust mobile solution, but is it a really bad idea in terms of picking up noise from the vehicle electrical system i.e. having the relay switch literally a few mm from the 12 volt relay coil? I can shield the relay(s) easily enough, but the audio signal will be close to the 12v relay coil no matter what I do.

Relay to Switch Audio Signal - Pelican Parts Forums

Relay to Switch Audio Signal. Oddball question here. I have been looking for a switcher that will allow switching from car audio source A or B to the amplifiers. The complication is that each source is five channels (LF RF LR RR sub). The switchers I’ve found are only two channel, and seem to be made for home audio.
