4K@30Hz HDMI Audio Extractor

The Jansicotek HDMI Audio Extractor splits one HDMI source into a video pass-through and separate audio outputs. It provides an optical Toslink SPDIF port and RCA stereo analogue jacks alongside the HDMI output. The unit is intended for users who need to send sound to an amplifier, soundbar or speaker system while keeping the picture on a TV, monitor or projector.

Thermals, noise and power draw

The device ships with a 5V/1A DC power adapter and runs without a fan, so it adds no audible noise to the setup. Power consumption is low enough for the supplied adapter to handle all conversion tasks. Normal operation stays cool to the touch during typical viewing sessions.

Behaviour under sustained load

The extractor maintains 4K@30Hz video with 36-bit deep colour and HDCP 1.4 compliance over long periods. Audio mode can be set to PASS, 2.0CH or 5.1CH to match the connected sound system. Supported formats include DTS-HD, Dolby TrueHD, LPCM 7.1, DTS, Dolby AC3 and DSD. The converter does not support ARC functionality.

Questions about this item

How do I connect the extractor between my 4K@30Hz source and display, and which step is often missed?

Connect the source to the HDMI input, the display to the HDMI output, then attach the 5V power adapter before selecting PASS, 2.0CH or 5.1CH audio mode; the step most often missed is powering the unit, without which no audio is extracted.

What ongoing maintenance or replacement will this extractor need?

No scheduled maintenance is required; only the external 5V power adapter may need replacement if it fails, while the extractor itself has no user-serviceable parts or consumable components.

What is the first limitation I will hit when running 4K video continuously through this device?

The HDMI 1.4b link caps video at 4K@30Hz with 36-bit deep colour, so sustained use cannot exceed that refresh rate or bandwidth even if the source and display support higher specifications.
