With this infrared extender you operate a maximum of 4 audiovisual devices in a closed cabinet with your own remote control. The Invisible Control Black 4 consists of an IR module including IR receiver and 4 IR emitter LEDs. You stick an emitter LED on each device to be operated. This way you can operate up to 4 devices that are in a closed cabinet with your own remote control. The IR module is a small box and you place it in sight.
You place the receiver (small black box) within sight of your remote control and it is connected to the transmitter(s) that you have attached to your audiovisual equipment. The signal from your remote control is forwarded to the transmitter(s) via the receiver. The transmitter then 'operates' your audiovisual equipment. This ensures that you do not have to open cupboard doors to operate your equipment.
