An IR emitter and receiver extension cable allows you to control equipment hidden inside a cabinet or entertainment center using a remote control.

To set up:

1. Connect the IR emitter head to the IR sensor window on the front of the equipment you want to control, such as a cable box or Blu-ray player. Ensure the emitter LED aligns with the IR sensor.

2. Route the cable outside the cabinet and plug the USB connector into a power source like a TV USB port. This provides power to transmit the IR signals.

3. place the IR receiver head outside the cabinet in a location with a clear line of sight to the room.

4. When aiming your remote, point it toward the IR receiver on the outside of the cabinet. The receiver will capture the signals and transmit them via the cable to the emitter head, which beams them to the equipment sensors inside the enclosed space.

5. The IR extension cable essentially extends the external IR receiver to the internal equipment for seamless control using your handheld remote from anywhere in the room.

An infrared (IR) emitter and receiver extension cable enables convenient remote control of entertainment equipment hidden inside cabinets or shelving.

This specialty cable has an IR receiver on one end to capture signals from a handheld remote. It transmits the signals via the cable to an IR emitter placed directly over the IR sensor window of devices like gaming consoles, streaming boxes, or soundbars mounted behind closed doors.

Using the cable avoids the need to leave cabinets open or equipment partially exposed for IR signals to reach. It also eliminates aiming frustration caused by narrow IR reception angles on many devices. With everything elegantly concealed and the extension cable in place, the equipment can be controlled seamlessly as if the cabinet doors did not exist.

So in situations where equipment must or should be hidden, an IR emitter/receiver extension wirelessly extends remote command functionality to enclosed gear. This maintains easy control while keeping the installation tidy for aesthetic or child/pet safety reasons. The cable becomes an invaluable problem solver for IR control challenges posed by equipment cabinets and shelving.
