Audio extraction for HDMI sources

The JTECH-AE4KA extracts audio from an incoming HDMI signal and sends it to an external sound system via Optical and RCA outputs while passing video to a display. It is designed for users connecting laptops, Blu-ray players or gaming consoles to speakers or receivers that lack HDMI inputs.

4K 60Hz pass-through with EDID control

Video passes through at up to 4K 60Hz 4:2:0, with 1080P and 720P also supported. A three-position EDID switch selects TV, 2CH or 5CH modes to match the source output to the connected audio system. The Optical output carries stereo and 5.1CH audio, while RCA provides stereo output.

Powered operation with ARC support

The unit includes a power adapter for stable operation. ARC functionality extracts audio from a compatible display through the Optical output only; eARC is not supported. Simultaneous Optical and RCA output requires the incoming audio format to be compatible with both connections.

Questions about this item

Will the JTECH-AE4KA pass 1080p at 60Hz from an older Blu-ray player to my TV while sending audio to a legacy receiver via RCA?

Yes, the extractor supports 1080p and 720p resolutions alongside 4K at 60Hz, so your existing Blu-ray player will pass video through the HDMI output while analogue stereo audio is available on the RCA jacks.

How can I confirm the extractor is correctly decoding 5.1-channel audio from my gaming console through the optical output?

Set the EDID toggle to the 5CH position, play a title with a Dolby Digital or DTS soundtrack, and verify your receiver or soundbar indicates a 5.1-channel bitstream on its display.

Does the box include an HDMI cable to connect the extractor between my laptop and monitor, or must I supply my own?

The package contains the audio extractor, a power adapter and a user manual only; you will need to provide the HDMI cables for the source and display connections yourself.
