All of Touchstone"s full size and mid-size line of TV Lift cabinets come "IR-ready", with a built in IR eye, so that you can hide your components behind closed doors, yet be able to operate them via remote simply by pointing your component"s remote toward the built-in eye. The Touchstone Home Products 70012 IR repeater kit comes with 3 emitters, an emitter control box, and an extra IR eye. The Touchstone IR Repeater Kit is all you need to be able to operate all of your components from one central "IR-ready" eye, which has been pre-installed and is conveniently located in the upper right corner of our full and mid-size main cabinets. If you plan on placing components in your side cabinets as many people do, the 3 emitters in the kit can handle that type of configuration.
