Non-Branded Single "Blink" emitter
Connect these emitters up to a IR splitter block, and use them to send infra-red signals to any infra-red controlled device, like a TV, Sky box, DVD, Hi-Fi, etc.
The Xantech branded emitters, have infra-red output, and a visible blinking LED facing away from the equipment. This allows visible confirmation of infra-red commands being sent.
Normal installation is via IR splitter block, then each emitter is placed directly over your equipment's IR "eye". An IR receiver may also be added which will allow you to hide your equipment out of sight whilst still allowing infra-red control.
