The Professional IR Extender system offers several new features including smaller form factor, aesthec designs, and increased compability. Like other IR Extender products in the our product range, this professional system support dual band IR signals and also RC-MM Protocol. Note: RC-MM is a new IR protocol with much shorter waves than a typical IR signal and uses less power. lt is becoming more prevalent with major brands. Mulple Funcons: Modern family loves to hide all their home theater Audio/ video systems and cables in cabinet to keep things neat and dy. However, remote controlling the A/V systems in the cabinet can be a frustraon due to the inability. This kit includes an IR receiver, a connecng block (which serves as a signal repeater), and IR emitters. The IR receiver is a small target device which communicate directly with your remote control. It can be mounted on your HDTV’s bezel or anywhere in the room where you will want to point your remote to but the IR Receiver must be in lineof-sight with your remote control. The IR receiver receives your remote control’s commands and sends the signal to the connecng block (which you can hide behind walls or cabinet). The connecng block then repeats and sends the same signal through the IR emitter (connected to the block). Your A/V system will received the signal/command from the emitter and react accordingly. (IR Emitter to be pasted on the IR sensor of the parcular A/V system).
