The KanexPro AUD-EXT-EARC100M extends HDMI eARC or S/PDIF audio up to 328ft (100m) 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.
Applications:
• Living Room and Home Theater: Extend TV eARC audio to a soundbar or AVR in a media cabinet across the room - Dolby Atmos, TrueHD, and DTS-HD MA pass through with full lossless fidelity.
• Hospitality Suites: Deliver eARC audio from in-room TV to centralized AV rack or per-room soundbar up to 328ft (100m) over existing CAT6 infrastructure - no additional audio cabling.
• Whole-Home and MDU Audio: Route eARC audio from main display to whole-home audio system or distributed amplifier over structured wiring - PoC powers remote RX from TX side.
• Bar and Restaurant: Extend TV audio to behind-bar or kitchen amplifier over CAT - CEC pass-through keeps TV remote volume control functional without additional control hardware.
• Dolby Atmos Rooms: Carry full Dolby Atmos and DTS-HD MA bitstreams from TV to remote AVR in dedicated home theater or premium hospitality audio environments up to 328ft (100m).
• Retrofit and Renovation: Add eARC audio extension to existing CAT infrastructure during AV upgrades - no new cable pull required, PoC eliminates need for power outlet at RX location.
