HDMI eARC w/ SPDIF Audio over CAT Extender 100m POC

Extends HDMI eARC or S/PDIF audio up to 100m/328ft over a single CAT cable, delivering lossless surround sound from a TV to a remote soundbar, AVR, or multi-room audio system. The transmitter connects to the TV’s eARC/ARC port and sends full-resolution audio — including Dolby Atmos and DTS-HD Master Audio — over standard CAT6/6a/7 cabling to a receiver at the remote audio endpoint.

For TVs without HDMI eARC, the built-in S/PDIF pass-through channel provides an independent optical audio path from the transmitter’s S/PDIF IN port to the receiver’s S/PDIF OUT port. Bi-directional Power over Cable eliminates the need for a power source at both ends, and CEC pass-through maintains device control across the link.
