4K Ultra HD 600 MHz HDBaseT Extender w/ HDR, RS-232, 2-way IR, and POL


4K Ultra HD HDBaseT™ Extender with 2-way IR, and POL

The GTB-UHD-HBTL 4K Ultra HD Extender uses Gefen’s implementation of the HDBaseT™ technology to extend HDMI up to 230 feet/70 meters at 1080p and up to 130 feet/40 meters at 4K, using one CAT-5e or better cable. Resolutions up to 4K Ultra HD (3840 x 2160 @ 60 Hz 4:2:0) with 7.1 channels of HBR (High Bit Rate) lossless digital audio are supported. This product provides 2-way IR extension between the Sender and the Receiver units, facilitating the control of A/V sources placed near the Sender unit and sending automation commands to the display or another device placed near the Receiver unit. Gefen’s Bi-Directional POL (Power Over Line) technology powers the Sender or the Receiver unit using the same cable that extends the HDMI signal. Only one of the two units will need a power supply. This feature simplifies installation in cases when an electrical outlet may not be available near the source or the display. Small, low profile enclosures can be securely surface-mounted and conveniently hidden away from sight.


1. Shielded (STP) CAT-5e or CAT-6A is recommended. Unshielded (UTP) CAT-5e or CAT-6A may be acceptable depending on cable quality but is not the preferred choice. Care should always be given to keep these cables away from power lines and other sources of electromagnetic interference.

2. This product supports sources up to 4K 300 MHz (60 Hz 4:2:0 or 30 Hz 4:4:4). It is not compatible with sources that are capable of HDR or 4K 600 MHz (60 Hz 4:4:4).
