What this extractor does

The Jansicotek unit splits an HDMI source into a pass-through HDMI video signal and separate audio paths via optical Toslink SPDIF and RCA stereo outputs. It handles resolutions up to 4K at 30 Hz with 36-bit deep colour and HDCP 1.4 compliance. Three audio modes — PASS, 2.0CH and 5.1CH — let you match the output to your sound system. The box includes a 5 V power adapter and a manual.

Check your source and display first

Verify that your playback device sends HDMI 1.4b video and that your screen accepts the same link without requiring ARC, because this extractor does not support ARC. Confirm your amplifier or soundbar has either an optical SPDIF input or RCA analogue inputs for the audio feed. The converter needs the supplied 5 V power adapter, so ensure a mains socket is available near the installation point.

Steady operation with constant video

Under continuous 4K 30 Hz playback the extractor maintains synchronous audio and video separation without signal loss. The fixed 36-bit colour pipeline and HDCP 1.4 handshake remain stable during long sessions such as film marathons or digital signage loops. Audio format support including DTS-HD, Dolby TrueHD and LPCM 7.1 is sustained across all three selectable modes without drop-outs.

Questions about this item

What comes in the box and do I need to buy any cables separately?

The package includes the extractor, a 5V/1A power adapter, and a user manual. HDMI, optical SPDIF, and RCA cables are not included and must be purchased separately.

Which audio mode — PASS, 2.0CH, or 5.1CH — should I select for my setup?

Choose PASS to forward the source format unchanged, 2.0CH for stereo-only systems, or 5.1CH when your soundbar or AV receiver supports 5.1 surround via optical or RCA outputs.

What does the 4K@30hz rating mean when I connect this to my TV and sound system?

The extractor passes video up to 4K at 30 Hz with 36-bit deep colour and HDCP 1.4 while simultaneously sending audio to optical SPDIF or RCA outputs for your amplifier or soundbar.
