I've found a little bit of info about these jacks on the "Remote Control" forum, but what I would like to know is if the Remote In jack can be used to hook up a small IR sensor which would feed the remote's signals into the receiver. My Denon is behind a cabinet door at about a 30-40 degree angle and has trouble seeing my remote. I'd like to put a small IR "eye" in a more open location and then plug the other end of the "eye" into the Denon's Remote In jack. Will this work? (I'm trying to avoid the pyramid devices).
