I've been looking at Xantech systems as a way to control my receiver from a second room. The receiver has a jack which according to the instructions I can use to connect it directly with the Xantech connecting block, no emitter necessary. Problem is, none of the literature I'm finding at Xantech and Parts Express's web sites tell me what I need to set that up. They only describe setups that use emitters. Can anyone clue me in if there is a special kit I'm overlooking or if I just need to buy an extra wire or what. Thanks!
