4K@60Hz HDMI ARC Audio Extractor

The avedio links Grey extractor pulls audio from an HDMI source and sends it to a display plus optical 5.1CH, stereo RCA or 3.5mm outputs. It also works in reverse, taking sound from a TV ARC port to external speakers. A USB-C 5V cable must be connected for power.

Upgrade from basic HDMI audio splitting

This unit replaces a simple HDMI splitter that only passes audio through the video cable. The jump is worth it when you need discrete optical 5.1CH or analogue stereo feeds for a soundbar, AV receiver or headphones while keeping the video path intact.

Handles 4K@60Hz video with multi-channel audio

The extractor passes 4K@60Hz video and supports PCM 2.1CH through all outputs or PCM 5.1CH through optical in OPT mode. Higher bitstream formats only produce sound on specific interfaces, so Dolby Digital Plus or DTS-HD streams will not play on every port.

Questions about this item

What HDMI port spacing does the 90 degree Grey housing need?

The 90 degree Grey housing uses an HDMI 22 connector layout, so allow enough rear clearance for the right-angle bend to sit flush against the source or display port.

Which DIP switch position and TV setting enable ARC extraction?

Set the DIP switch to TV mode, enable CEC on the TV, and connect the TV's HDMI ARC port to the extractor's HDMI OUT using an ARC-capable HDMI cable.

When will the USB-C 5V power cable need replacing?

Replace the USB-C 5V power cable if the extractor loses power intermittently or fails to start, since the unit requires that cable for every operating mode.
