Purpose and audience

This Jansicotek HDMI audio extractor splits the digital audio from an HDMI source into optical TOSLINK SPDIF and analog RCA stereo outputs while passing the original video through an HDMI output. It is built for owners of soundbars, AV receivers or amplifiers that lack HDMI inputs but need audio from Blu-ray players, consoles, streaming sticks or PCs.

Upgrade path and value

The unit replaces a direct HDMI-to-HDMI connection when the display or projector cannot send audio to an external sound system. The jump is worth it when the source device outputs 5.1-channel Dolby Digital or DTS over HDMI and the audio gear only accepts optical or RCA; it also adds 4K 30 Hz and 36-bit deep-colour pass-through that older splitters cannot handle.

Installation and common issues

Power the extractor, connect the source to the HDMI input and the display to the HDMI output, then link optical or RCA cables to the audio system. Select PASS, 2CH or 5.1CH with the mode switch to match the receiver. The red LED confirms power and the green LED confirms a valid HDMI handshake; no green light usually means an HDCP mismatch or a cable longer than 49 ft with AWG26 wiring.
