I just heard this term "ducker" circuit and I am told that is what I am looking for. I am working with an automotive intercom headset system and I am looking to introduce emergency radio traffic into the system but I want the primary audio to drop to very low or 0 during emergency radio reception. I also plan on introducing low level audio for background music.
Here is what I know:
2 additional audio inputs into the intercom system. 1 priority - 1 background
I have 8 volts DC to run the circuit.
very low operating current
The IC needs to be in a DIP design
It needs to be as small as possible but yet I can still solder...
I apologize if this is the wrong forum for this question. I figured if anyone could guide me to the correct chip (s), it would be the chip manufacturer.
Thank you,
