This question is related to one of my older questions: Push to talk mic over music
I was thinking how to get rid of the mechanical action of the relay so I wanted to know if it is possible to drive a signal through a SSR (more exactly G3MB-202P DC5).
In the diagram below the main idea is that when the button is not pressed, the music is playing at maximum, and when the button is pressed, the music is lowered through the potentiometer, and at the same time the microphone amplifier is powered on. The expected output should be the mic volume higher than the music, and both mixed together.
7404 inverter is used because I need some kind of NO / NC relay which is not available for SSR.
The question is: is it possible to drive a sound signal through SSR? Will it be a plus or a minus compared to driving the signal through normal relays?
After reading all the answers, some documentation and going to my local electronics shops I came to two available ICs: CD4066B & CD4016B. I believe they both work for my purpose, but I've only tried CD4066B following this diagram.
Works like a charm and It's exactly what I wanted :) Thanks!
