Hello!
I'm trying to design an audio source signal selector, for 3 stereo inputs, and one stereo output. My idea looks like this:
A micro controller will choose which signal source to switch on (never more than 1 at a time). But I need a device (in red in the pseudo-schematic above) to actually do the switching on command.
It totally looks like a relay would do the trick, but they're really bulky for the purpose; I'm trying to keep this as small as possible, discrete SMD components are very much preferred.
I thought about using transistors, but I'm not sure how to place them here - and I only know a bit of BJTs, I don't know if JFET or MOSFET would be more suitable for this.
Can anyone help me with this?
I'm looking forward to learning, so if you bring a brief explanation as well I would really appreciate it.
