Hi Rogerio,

I think you need to specify this "audio input" a bit more: what kind of
bandwidth does it have? what kind of noise can we expect on it? is it
wireless or wired? Do you need full duplex transmission?

5 miles is a long distance. A wired link is probably impractical because of
the need to lay cable or fiber over that whole distance.

Tell us some more about what you are doing and what exactly this "audio
input" is.
