I have an older M&S intercom system through my house with CD, AM/FM and Aux input via RCA connections. I am looking to to plug my HomeSeer into the Aux input to play my digital collection through the house. The problem is that the M&S is about 30-40 feet away from my HomeSeer ( line of site) but direct wiring would be difficult given the layout of our attic. Is there a reliable wireless transmitter that somebody could suggest. One that could be placed in the wall and still be powerful enough to reach the HomeSeer. Any thoughts?
