Key Features

Reference-Grade 4K Delivery: Extends uncompressed 4K@60Hz 4:4:4 8-bit video, USB 2.0 data, analog audio, and RS-232 control over a single CAT6a cable, reaching 40m (131ft) at 4K@60Hz and up to 70m (230ft) at 4K@30Hz.

 

Full-Function USB-C Input: One USB-C port carries 4K DisplayPort Alt Mode video, USB 2.0 data, and up to 60W of laptop charging, streamlining BYOD connections for conference rooms, educational facilities, and hybrid collaboration spaces.

 

Flexible Audio Architecture: Supports multi-channel formats including PCM 2.0/5.1/7.1, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, and DTS:X, with analog line-in pass-through from sender to receiver and independent audio de-embedding available on both units.

 

Single-Supply Power Flexibility: Bi-directional PoH+ lets the included 20V/6A power adapter power both sender and receiver from either end, cutting cabling and outlet requirements on install.

 

Built-in KVM USB Hub: Both units feature 2x USB Type-A and 1x USB Type-C device ports with 2.5A shared power for keyboard, mouse, camera, and touch panel control, with USB 2.0 pass-through up to 300Mbps.

 

Installation Agility: DIP switches on each unit configure HDCP, EDID (copy or fixed resolution), and RS-232 modes in the field, while firmware can be upgraded over RS-232, keeping the system current without downtime.

How It Works

The Gefen GF-EXT-UCK-HBT3 uses HDBaseT 3.0 technology to transmit uncompressed 4K@60Hz UHD video, USB 2.0 data, and power over a single CAT6a or higher cable, extending high-resolution content and peripheral control up to 40m (131 feet) at 4K@60Hz 4:4:4 and up to 70m (230 feet) at 4K@30Hz. 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, allowing a single 20V/6A power adapter connected to either the sender or the receiver to power both units, simplifying setup and reducing cable clutter. The system also supports audio de-embedding on both the sender and receiver, plus analog line-in pass-through, enabling users to route audio flexibly from sources to external audio systems.


With DIP-switch configurable EDID and HDCP management and real-time, uncompressed transmission with no latency, the extender ensures consistent display compatibility and fast, natural input response for KVM control. Its robust design, built-in KVM hub with USB 2.0 pass-through up to 300Mbps, and support for multi-channel formats including Dolby Atmos and DTS:X ensure reliable operation in demanding professional environments, such as conference rooms, educational facilities, and hybrid collaboration spaces.
