4K@30Hz HDMI Audio Extractor

This Jansicotek HDMI audio extractor separates the embedded digital audio from an HDMI source and delivers it through both optical Toslink SPDIF and RCA L/R stereo outputs while passing the original video signal to an HDMI display. It supports video resolutions up to 4K at 30 Hz with 36-bit deep colour and HDCP 1.4 compliance. The unit includes a 5 V power adapter and a user manual.

Suited for legacy audio systems, not ARC setups

The extractor is ideal for connecting modern HDMI sources such as a Blu-ray player, Apple TV, PS4, Xbox or PC to an older amplifier, soundbar or AV receiver that lacks HDMI inputs. It offers three audio-mode settings — PASS, 2.0CH and 5.1CH — to match the capabilities of the connected audio equipment. It does not support ARC, so installations that rely on Audio Return Channel for return audio cannot use this device. Buyers needing 4K at higher refresh rates or HDR pass-through should consider a different solution.

HDMI 1.4b with 36-bit deep colour

The single specification that determines compatibility is the HDMI 1.4b interface limited to 4K at 30 Hz and 36-bit deep colour. This ceiling governs the maximum video resolution and colour depth the extractor can pass to the display.

Questions about this item

Does the extractor generate noticeable heat or noise when powered continuously?

The unit is a passive signal device with no fan; the included 5 V power adapter runs cool and silent during all-day use.

What cables must I already have to connect a source and an audio system?

You need an HDMI cable for the source, another HDMI cable for the display, plus either a Toslink optical cable or a pair of RCA cables for the audio output.

Will a 1080p-only monitor still pass 5.1-channel audio to my older AV receiver?

Yes, the extractor accepts 1080p at 36-bit deep color and can output 5.1-channel audio via SPDIF while the monitor receives the video unchanged.
