Gefen GTB-UHD600-HBTL 4K Ultra HD 600 MHz HDBaseT Extender

Brand: Gefen


Extend Full-Bandwidth HDMI 2.0 w/ HDR up to 40 meters/132 feet, over a single CAT-5

The Gefen GTB-UHD600-HBTL is a compact and high-performance solution for extending full-bandwidth HDMI 2.0 audio/video with HDR up to 40 meters (132 feet), over a CAT-5e or better cable. It supports 18.2 Gbps of data throughput and 600 MHz TMDS Clock frequency, the highest specified under the HDMI 2.0 standard. This extender uses HDBaseT technology along with Gefen’s visually lossless proprietary compression algorithms with very high PSNR (Peak Signal to Noise Ratio), to accommodate resolutions up to 4K Cinema-DCI (4096 x 2160 to 60 Hz 4:4:4) and 4K Ultra HD (3860 x 2160 to 60 Hz, 4:4:4) with HDR. High Dynamic Range (HDR) delivers greater contrast between light and dark areas of a video image, resulting in tremendous improvement in picture quality and color depth. HDCP 2.2 and the legacy HDCP 1.4 are both supported. The GTB-UHD600-HBTL also supports 1080p Full HD, WUXGA (1920 x 1200), 3DTV, and Deep Color (up to 1080p resolution). Highest performance multichannel digital audio including 7.1 channels of LPCM and HBR (High Bit Rate) digital audio formats, such as Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-HD Master Audio are passed through to the HDMI outputs. The GTB-UHD600-HBTL 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, and accommodate Gefen locking HDMI cables for secure connections.
