Audio extraction for 8K sources

The JTECH-8KAE pulls audio from an HDMI signal and routes it to external sound systems through optical, 3.5mm stereo, or HDMI audio outputs while passing 8K 60Hz or 4K 120Hz video to a display. It suits installers who need to separate sound from a high-resolution video chain without degrading the picture.

Sustained signal handling

The extractor maintains continuous HDMI 2.1 bandwidth for HDR10+, Dolby Vision and HLG pass-through during long viewing sessions. HDCP 2.3 compliance and CEC control remain active across the link, so copy-protected streams and volume commands do not drop out after extended use.

Thermals noise and power

The compact black enclosure runs silently with no moving parts and draws minimal power from the included supply. Heat stays low during typical operation, making it suitable for enclosed cabinets or behind mounted displays where airflow is limited.

Questions about this item

Does the JTECH-8KAE generate noticeable heat or fan noise when passing 8K 60Hz video all day?

The extractor has no fan and runs silently; its low-power HDMI 2.1 circuitry stays cool during continuous 8K@60Hz or 4K@120Hz pass-through.

Which cables and external audio gear must I already own to use the optical, 3.5 mm and HDMI audio outputs?

You need an HDMI source cable, a display cable, plus either an optical cable for 5.1 sound, a 3.5 mm stereo lead for analogue, or an HDMI cable to an AVR for 7.1 audio.

Will CEC volume control still work if I keep my older ARC-only soundbar instead of upgrading to eARC?

Yes, the unit supports both eARC and ARC extraction, so CEC volume commands from the TV pass through to an ARC soundbar without requiring an eARC model.
