HDMI audio extractor for home theatre setups

This Jansicotek unit extracts the digital audio embedded in an HDMI source and sends it to optical SPDIF or RCA L/R outputs while passing the original video and audio through to an HDMI output. It is aimed at users who need to connect a modern source to an older amplifier, soundbar or AV receiver that lacks HDMI inputs. The device supports three audio modes — PASS, 2CH and 5.1CH — to match different sound systems.

Thermals noise and power in normal use

The converter draws power from the HDMI source and runs without a fan, so it adds no audible noise to a quiet listening room. Its compact black enclosure stays cool during typical operation, and LED indicators show power status (red) and a successful HDMI handshake (green). No external power supply is required for standard cable runs up to 49 ft with AWG26 cable.

What this replaces and when the upgrade is worth it

It replaces a direct HDMI-to-HDMI cable when the display or projector cannot pass audio to a separate sound system. The jump is worth it if you need 4K@30 Hz video with 36-bit deep colour and 5.1-channel Dolby Digital or DTS via optical, but do not need ARC support or 4K@60 Hz bandwidth.

Questions about this item

How do I connect the extractor between my 4K source and display, and which step do people often miss?

Connect the source to the HDMI input, the display to the HDMI output, then attach either the optical SPDIF or RCA L/R cables to your audio system. The step often missed is setting the audio mode switch to PASS, 2CH or 5.1CH to match the connected equipment.

What ongoing maintenance or replacement will this unit need?

No internal parts require scheduled replacement. Only the external HDMI, optical and RCA cables may need swapping if they become damaged or if you upgrade to longer runs beyond the 49 ft AWG26 limit.

What is the first limitation I will hit during long 4K playback sessions?

The maximum supported video resolution is 4K at 30 Hz with 36-bit deep colour; higher refresh rates or 4K at 60 Hz are not supported, so that frame-rate ceiling appears first under sustained use.
