HDMI ARC Audio Extractor

The Mediasonic avedio links HDMI ARC Audio Extractor separates audio from an HDMI source and sends it to both optical SPDIF and 3.5 mm stereo outputs while passing video through to a display. It suits anyone connecting a console, streaming stick or PC to a soundbar or amplifier that lacks HDMI inputs.

8K 60Hz and 4K 120Hz video pass-through

The unit handles video up to 8K at 60 Hz and 4K at 120 Hz with HDCP 2.3 compliance and colour depths of 24, 30, 36 and 48 bit. Supported resolutions include 480i, 480p, 576i, 720p, 1080i and 1080p so existing 1080p sources remain compatible.

Requires USB 2.0 power and an HDMI source with ARC

A USB 2.0 port supplies power for the extractor and the ARC return path from a compatible TV. Three audio modes — Pass, 2CH and 5.1CH — let you match the output to a stereo headphone, soundbar or multichannel receiver without needing a separate HDMI audio board.

Questions about this item

What does the 8K@60Hz and 4K@120Hz rating mean for my setup?

It means the extractor passes those video resolutions and refresh rates through to your display without downscaling, so a compatible source and screen can run at their native 8K 60Hz or 4K 120Hz while audio is pulled off separately.

Which HDMI standard limits the bandwidth here?

The device supports up to HDMI 2.1 and HDCP 2.3, so the 48 Gbps ceiling of HDMI 2.1 is the practical limit for uncompressed 8K 60Hz or 4K 120Hz signals.

What does the unit need to fit and stay powered?

It requires a free USB 2.0 port or charger for power, one HDMI input from your source, one HDMI output to the display, and either an optical TOSLINK cable or a 3.5 mm stereo cable for the extracted audio.
