The GefenToolBox Extender for HDMI with POL uses Gefen's implementation of the HDBaseT technology to extend HDMI up to 230 feet (70 meters) using one CAT-6 cable or up to 198 feet (60 meters) using one CAT-5e. Resolutions up to 4K Ultra HD with 7.1 channels of HBR (High Bit Rate) lossless digital audio are supported. This product also provides 2-way IR extension between the Sender and the Receiver unit, allowing the transfer of IR commands from one remote location to the other. Bi-Directional IR can be used to control A/V sources placed near the Sender unit and to send IR automation commands to devices placed near the Receiver unit. Gefen POL (Power Over Line) technology powers the Receiver unit using the same cable that extends the HDMI signal from the Sender unit. This feature eliminates the need for an external power supply at the Receiver unit and simplifies installation.
