How It Works

The Gefen GF-EXT-HDe-HBT3 uses HDBaseT 3.0 technology to transmit uncompressed 4K@60Hz video, eARC/ARC audio, and control signals over a single CAT6a cable up to 330 feet. Connect your HDMI source to the sender unit (TX), which encodes the 18Gbps signal and transmits it to the receiver unit (RX) at your display location. The system uses bi-directional Power over Cable (PoC), so you only need to power one unit—it automatically supplies power to the other through the network cable. Smart EDID management maintains handshake integrity between devices while adaptive audio intelligence automatically detects and optimizes PCM or bitstream sources, with options to de-embed audio via analog or optical outputs at either end. LED indicators provide real-time monitoring of power, link, video, and eARC status throughout operation.
