Carry uncompressed HDMI video, USB 2.0 KVM traffic and audio between a local source position and a remote display or control position across an HDBaseT 2.0 link. The GEFEN GF-EXT-HDK-HBT2 reaches up to 100 m and supports 8K at 60 Hz with 4:2:0 chroma or 4K at 120 Hz. HDR10, HDCP 2.3 and Dolby Audio support protected, high-resolution AV signals in control-room and production environments. USB 2.0 KVM extension places keyboard, mouse and compatible USB control devices at the remote end while the host remains at the source end. EDID management and HPD stability support display negotiation and source-to-display connection behavior. Analog audio de-embedding provides a separate analog audio output path, while eARC compatibility supports installations that require audio-return functionality. Bi-directional Power over HDBaseT can reduce the number of separate power connections required between endpoints. Both sender and receiver are included for a complete point-to-point extension link. Heavy-duty metal housing suits fixed professional AV installations, and field-upgradable firmware supports product maintenance over its service life. Within the HDMI KVM extender range, this model combines 8K at 60 Hz video support, 4K at 120 Hz operation, HDBaseT 2.0 transport, USB 2.0 KVM extension and integrated audio handling in one paired-endpoint system.
