Example wiring diagram.

The XTND Audio (100) eARC is being used to extract multi-channel audio from a TV app (up to Dolby Atmos/using HDMI only) which is then being routed to the XTND Audio (100) eARC Receiver. This audio is being fed via a HDMI cable to the AVR along with any CEC commands from the display remote such as volume control to provide digital audio and control over distance. Pro Tip: This XTND works in reverse. This means that the Transmitter is located at the display location as that is where the audio source is located.
