The Infrared Remote Extender Cable, also known as the IR Repeater Cable, allows you to extend the IR signal from your TV to a video source like a Blu-ray player. With a 2m launch line length and a 4m receiving line length, this cable provides flexibility in placement. The IR remote control cable is perfect for home theater setups, as it repeats the IR signal to a DVD player, STB box, Receiver, or other A/V source with an IR sensor. You can route the cable out of sight with a wall mounted TV and install the IR Transmitter end in a concealed equipment closet to hide a CATV box and control it remotely. Installation is simple and hassle-free. The lightweight IR cable can be easily located near the source sensor to repeat the signal to the source. The IR Receiver can be placed in a convenient location with line of sight of your hand-held remote. Both the IR Tx and Rx cables have adhesive circles on the back for easy mounting. This USB powered IR extension cable comes with an integrated Y-cable to receive 5V USB power. You can connect the USB cable to a TV USB power port or to a USB wall charger for power supply. The IR extender cable is universally compatible with most A/V equipment that has infrared sensors (not RF). It provides a 30-degree IR Receiver angle, giving you plenty of leeway to get the right angle with your remote for seamless control.
