So, I'm wanting to mount an in-wall rack to hide my AV gear. Right now, all that I use to control them are my receiver remote, my PS3 controller, a wireless mouse, a wireless keyboard, and my TV box remote. I've seen some information on IR repeaters etc, but I'm not really sure if these would work for me. The cable for the repeater, unless they sell wireless ones, would need to be at least 25' long. Do I need more than one? Or are some of the technologies my controllers use not IR? Thx in advance.
