For applications where ARC signals need to be extended above HDMI cabling limitations to an amplifier or distributed audio system.
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 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).
