Audio extraction for HDMI sources

The Jansicotek 4K HDMI Audio Extractor Splitter takes a single HDMI input and provides simultaneous HDMI video pass-through plus optical Toslink SPDIF and RCA L/R stereo analogue audio outputs. It is intended for users who need to separate audio from a source such as a Blu-ray player, games console or streaming stick and send it to an amplifier, soundbar or speaker system while keeping the video signal intact for a TV, monitor or projector.

Passive operation with external power

The unit ships with a 5 V DC power adapter and draws its operating power from that supply rather than from the HDMI source. In normal use it simply de-embeds the audio stream and forwards the video without adding active cooling, so there is no fan noise and no measurable thermal load on the source device. The splitter supports HDMI 1.4b and HDCP 1.4 signalling while maintaining the original video timing.

Sustained 4K@30 Hz throughput

Under continuous operation the extractor maintains video resolutions up to 4K at 30 Hz with 36-bit deep colour and 3D support, passing the signal through to the HDMI output without degradation. Audio formats including DTS-HD, Dolby TrueHD, LPCM 7.1, DTS, Dolby AC3 and DSD are transmitted over the optical and analogue outputs according to the selected PASS, 2.0CH or 5.1CH mode. The device does not support ARC functionality.

Questions about this item

How do I connect the 5V power adapter and switch between PASS, 2.0CH and 5.1CH modes on the Jansicotek extractor?

Plug the supplied 5V/1A DC adapter into the unit, connect an HDMI source to the input and a display to the HDMI output, then use the three-position audio-mode switch to select PASS for bitstream passthrough, 2.0CH for stereo downmix or 5.1CH for surround downmix.

Will the optical SPDIF or RCA L/R outputs degrade over time and need replacement?

Both the optical Toslink port and the RCA stereo jacks are passive connectors with no moving parts; they do not wear out in normal use and require no scheduled maintenance.

What video ceiling will I hit first when running a 4K source continuously through this splitter?

The HDMI 1.4b link caps the signal at 4K@30Hz with 36-bit deep colour, so sustained 4K playback is limited to 30 frames per second regardless of source capability.
