PulseAudio PAEXARC1 is an ARC Digital Audio Extender over CAT5e CAT6 Ethernet

The PulseAudio PAEXARC1 is an ARC Digital Audio Extender that allows digital audio to be routed from a display to a remote location or amplifier over a single Cat5e/6 cable up to 492ft (150m). For displays without ARC capability, or when ARC settings are not working as they should, the built-in “ARC Backup Plan” is featured where audio can still be extended utilizing SPDIF.

The range of the PAXEARC1 will vary depending on the HDMI/ARC sample rates. For instance, higher sample rates, 192kHz, will be rated at 295ft (90m), while lower sample rates, 96kHz, will be rated at 492ft (150m).
