The PulseAudio PAEXARC1 is an ARC Digital Audio Extender that allows digital audio to be routed from a display, back 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 PAEXARC1 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).
