4K HDMI Audio Extractor

The Jansicotek extractor takes a single HDMI source and splits the signal into a pass-through HDMI output plus optical Toslink and stereo RCA analogue audio outputs. It is intended for users who need to feed a separate sound system, amplifier or soundbar while keeping the video path intact to a TV, monitor or projector. The unit ships with a 5 V power adapter and a user manual.

Capacity and headroom

Video resolution is supported up to 2160p at 30 Hz with HDMI 1.4 b and HDCP 1.4, alongside 1080p, 3D and 36-bit deep colour. Audio formats handled include DTS-HD, Dolby TrueHD, LPCM 7.1, DTS, Dolby AC3 and DSD. Three selectable modes — PASS, 2.0CH and 5.1CH — let the user match the output to the connected audio equipment.

Interface limits

The HDMI output simply mirrors the input signal and does not support ARC functionality. Optical and RCA outputs carry the extracted audio only, so the connected sound system must accept one of the listed formats. The converter requires external power and will not operate from the HDMI bus alone.

Questions about this item

Will the 4K@30Hz HDMI pass-through still work if my TV only accepts 1080P signals?

Yes, the extractor passes the original video through its HDMI output while downscaling to 1080P is handled by the display; the splitter itself supports up to 4K@30Hz and 1080P without altering the signal.

How can I verify the audio mode switch is set correctly for my 5.1CH soundbar?

Set the three-position switch to 5.1CH; the extractor will then output multichannel audio via the optical Toslink port, and you should hear surround sound from the soundbar when playing 5.1CH content.

Does the package include the optical and RCA cables needed to connect my amplifier?

The box contains the extractor, a 5V/1A DC power adapter, and a user manual; optical Toslink and RCA stereo cables are not included and must be purchased separately.
