Hello everyone:

I'm looking for a schematic for a audio combiner that has a mute or cut-out
that mutes the non priority input when the priority input has voltage. I
want to make an audio combiner to listen to music from a CD Player in a
aircraft with my headset. I want to have the signal from the CD player cut
out when I have a transmission coming in over the aircraft radio.

Thanks in advance to anyone that can help.

Rob,

I want to have the signal from the CD player cut out when I have a
transmission coming in over the aircraft radio.

A much simpler approach would be to mix the music and radio at a fixed level
with the radio, say, 20 dB louder. Then feed that mix into a limiter whose
threshold is set to reduce the volume by 20 dB when the louder radio comes
on. This way you can use a simple passive mixer (two resistors) and a cheap
compressor, as opposed to a custom circuit that gates one signal based on
another.
