Audio In jack on 50xxCTC

Hi,

How does the 'audio in' jack on the colour touch's function? Have had a good look through these forums and google but have come up empty handed...

Does whatever audio is getting sent in, come directly out the built-in speaker?
If so, what about volume control? - Does that have to be controlled externally...?

Trying to possibly utilise the touch as an intercom interface so as to reduce wall clutter.


Thanks,
Matt

 

I was thinking along the lines of possibly using the audio in to utilise the built-in speaker which would be fed directly from a door station mic. Then install a mic at each CT and connect them to a basic 1 in (door station speaker), multiple out (CT mic's) switch. (ie: something like http://www.extron.com/product/product.aspx?id=sw8a&subtype=12&s=4)

Correct me if I'm wrong but the echo cancellation problem would be if I were to put a mic behind the CT and connect it to the audio in? So reading between the lines the audio in is directly connected to the built-in speaker, yes?

I like the software support for local audio control. Reckon its a great idea! Maybe a possible feature for the future...?

Cheers,
Matt

 

No. It goes into the processor board, but is not used for anything at the moment.
