Jansicotek 4K 60Hz HDMI 2.0 Audio Splitter

This splitter extracts audio from an HDMI source and sends it to three separate outputs: HDMI ARC, SPDIF optical and analogue RCA plus 3.5 mm jack. It is aimed at users who need to connect a 4K source such as a games console, media player or PC to a display while feeding a separate amplifier or soundbar. The unit requires the included 5 V power adapter to operate.

HDMI 2.0 bandwidth and cable limits

The device handles a maximum bandwidth of 600 MHz and a baud rate of 18.5 Gbps, supporting 4K at 60 Hz with YUV 4:4:4 colour. Input and output cables must not exceed 10 m when using AWG26 HDMI 2.0a standard cables. HDCP 2.2 is supported for protected content, and the extractor passes HDR10, Dolby Vision and Dolby Atmos metadata through the HDMI ARC path.

Check your source and audio gear before ordering

Verify that your source device can output audio in one of the supported digital formats such as LPCM 7.1, DTS-HD, Dolby TrueHD, DTS, Dolby AC3 or DSD. The extractor provides stereo RCA, 3.5 mm and SPDIF outputs but does not decode multichannel streams into discrete analogue channels. Ensure your amplifier or soundbar accepts the chosen connection type and that the HDMI ARC port on your display is enabled for audio return.

Questions about this item

Which audio output should I pick — SPDIF, RCA stereo or the 3.5 mm jack?

Use SPDIF for multi-channel formats such as Dolby Atmos or DTS-HD, RCA stereo for a simple analogue amplifier, and the 3.5 mm jack for headphones or a portable speaker.

What does the 4K 60 Hz rating mean when I connect a console or media player?

The extractor passes 4K at 60 Hz with YUV 4:4:4 colour, HDR10, Dolby Vision and HDCP 2.2, so the TV receives the full signal while audio is split off.

How does the HDMI 2.0b interface limit the bandwidth in practice?

The link runs at 600 MHz with a maximum baud rate of 18.5 Gbps, capping video at 4K 60 Hz 4:4:4 and supporting deep colour up to 36-bit.
