How It Works

The Gefen GF-EXT-HDK-HBT2 uses HDBaseT 2.0 technology to transmit uncompressed ultra-high-definition HDMI video and USB signals over a single CAT cable, extending high-resolution content and peripheral control up to 100 meters. This eliminates the need for multiple cables, reducing installation complexity while preserving signal integrity.

Bi-directional Power over HDBaseT (PoH+) supplies power through the same cable, simplifying setup and reducing cable clutter. The device also supports audio de-embedding and eARC, enabling users to route audio flexibly from HDMI sources to external audio systems.

With advanced EDID management and low-latency signal processing, the extender ensures consistent display compatibility and fast, natural input response for KVM control. Its robust metal enclosure, heavy-duty housing, multi-region power supply, and reinforced connectors ensure reliable operation in demanding professional environments, such as control rooms and production suites.
