4K Ultra HD HDBaseT 2.0 Extender

4K Ultra HD HDBaseT 2.0 Extender


With Ethernet, RS-232, 2-way IR, 2-way Audio, and Bi-Directional POH 

The EXT-UHDA-HBT2 HDMI Extender over HDBaseT™ uses Gefens implementation of the latest HDBaseT 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. The Gefen Syner-G 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.

Video Support

Resolutions up to 4K Cinema-DCI (4096 x 2160 at 24 or 30 Hz 4:4:4) and 4K Ultra HD (3860 x 2160 at 60 Hz, 4:2:0 or 30Hz 4:4:4) are supported. This product is compliant with the latest HDCP 2.2 protocol as well as HDCP 1.4.

Audio Support

The EXT-UHDA-HBT2 supports Stereo and Multichannel digital audio including 7.1 channels of LPCM as well as High Bit Rate (HBR) digital audio formats such as Dolby® TrueHD and DTS-HD Master Audio. TOSLINK® Optical Digital Audio can be sent from the display side back to the source and analog audio can be extended from the source side to the Receiver.

IP & Serial Extension

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.

Bi-Directional Power Over HDBaseT

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.
