intercom circuit Jim Weir

Dear Sir ,

Complements of the season.

I am a 50 year old pilot who has an ultralight , 2 place with a Filser
radio and want to incorporate the following -:

Audio input from an IPOD ïƒ* Input 1
Normal VHF radio comms ïƒ* Input 2 which must override / auto mute the
input 1.
Output to headphones ïƒ* output 1
Output to a digital recorder for cockpit voice recording ïƒ* output 2


Can your summer circuit be used an if so how does the auto mute
activate eg can I change the input resistors to prioritise the Input 2.



Thanks
Hedley
