Hi, I am working on trying to build my own helmet communication system and would like to have, for starters, a system with 2 inputs and one output. With the 2 inputs one would be a walkie talkie and the other would be a mp3 player. So, I would like it to play the music until someone speaks on the 2 way and at that point the music would be cutout completely and all you will hear is what is on the 2 way until they are done talking at which point you can hear the music again.
Thanks for the help.
