The EXT-UHDA-HBT2 uses Gefen's implementation of the latest HDBase 2.0 technology to extend HDMI up to 330 feet (100m) at 4K, using one CAT-5e cable. 1080p Full HD and 1920 x 1200 (WUXGA) 8-bit video can be extended up to 495 feet (150 meters). The new HDBaseT 2.0 Colligo platform provides additional features such as 2-way audio extension and ensures an even more robust and resilient connection than the industry standard HDBaseT. Resolutions up to 4K DCI-Cinema (4096 x 2160 @ 30 Hz 4:4:4) and 4K Ultra HD (3840 x 2160 @ 60 Hz 4:2:0) along with 7.1 channels of LPCM and HBR (High Bit Rate) lossless digital audio are supported. Supported HBR formats include Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-HD Master Audio. Ethernet connection for a Smart TV can be extended from the source side to the viewing location without the need to run a separate cable. RS-232 and 2-way IR are transferred between the Sender and the Receiver to control the A/V source and the display. TOSLINKĻ Optical Digital Audio can be sent from the viewing location back to the source and analog audio can be extended from the source side to the Receiver. Bi-Directional POH (Power Over HDBaseT) technology provides power from the Sender to the Receiver and vice versa, using the same CAT-5 cable that extends the HDMI and control signals. Only one of the two units needs an external power supply. The POH standard ensures compatibility with other POH class-compliant devices. The Gefen Syner-GŠ software with its powerful EDID Management capabilities speeds up configuration, performs real-time performance audits via Link Monitoring, and simplifies in-field firmware updates. Low profile, surface-mountable Sender and Receiver units fit in tight places and accommodate Gefen locking HDMI cables for secure connections.

Note: Shielded (STP) CAT-5e or better cable is recommended. Unshielded (UTP) CAT-5e or better cable may be acceptable depending on cable quality, but results could vary. Care should always be taken to keep the link cable away from power lines and other sources of electromagnetic interference.
