As a follow up question, I am wanting to control local AV equipment in one of the wall plate rooms, as well as the remote AV equipment via the Avatrix. So this is really an IR and remote control question: All the main sources are in the home theater connected via the Avatrix, in the room at the wallplate I have the TV, and in a closet i have a receiver to drive the audio in the room, as well as a local CD/DVD player. I would like to use a universal remote. The "by the book" method would be to put in a Xantech IR receiver connected to the wall plate, AND another one of the same to a connecting block with flashers to drive the hidden local DVD and Receiver.
My question: Could I do this with one IR receiver using mini-stereo Y cable, and if so, what about the 12V power?
The problem I forsee here is that using a splitter like that typically halves the signal level and power delivered. However, I would recommend contacting the company that makes the IR products you anticipate using to ask this question, as there could be variances among brands as to how well this works.
As an alternative, if I bought a Harmony 890, and set its RF receiver in the closet to drive the local components, could I take one of its mini-stereo jacks meant for a flasher and drive the IR input into the wallplate of the Avatrix. It seems a waste to take the remote signal from RF, convert in the harmony receiver to IR then convert the IR back to your wall plate
That should work fine. What you describe is used fairly regularly to obtain the benefits of an RF system while remaining compatible with an IR infrastructure.
