4K HDMI Audio Extractor
The ESTONE 4K HDMI Audio Extractor separates audio from an HDMI source and delivers it through three outputs simultaneously. It passes the video signal onward via HDMI while providing optical TOSLINK and analog RCA stereo connections. The unit supports 4K resolution at 30 Hz and deep colour up to 36 bit per channel. It is suited for home-theatre installations that require audio routing to a soundbar or AV receiver.
Check HDMI version and audio format needs
Verify that your source device outputs HDMI with embedded audio and that your display accepts the 4K 30 Hz signal passed through the extractor. Confirm whether your audio system requires 5.1 channel Dolby Digital or DTS via optical, or only two-channel PCM over RCA. The extractor does not support Dolby Digital Plus, and PS3 consoles are limited to stereo output. Cable runs up to 49 ft with AWG26 HDMI cable are supported.
Sustained operation with LED status
During continuous use the converter maintains stable signal separation without frame drops at the rated resolutions. A red LED confirms power is applied, while a green LED illuminates when a valid HDMI sink is detected. The three audio mode options — Pass, 2CH and 5.1CH — remain selectable without interrupting the video path. The metal enclosure aids heat dissipation during extended sessions.

Questions about this item
Does the box include the HDMI cables I need to connect my source and display?
The unit itself is supplied; HDMI cables are not included and must be purchased separately to link your source and display.
Should I use the optical TOSLINK or the analogue RCA outputs for my soundbar?
Use the optical TOSLINK output for 5.1‑channel Dolby Digital or DTS; the RCA stereo outputs carry only 2‑channel PCM audio.
Will 4K 30 Hz video pass through to my TV without downscaling?
Yes, the extractor passes 3840×2160 at 30 Hz and 4096×2160 at 30 Hz to the HDMI output while simultaneously splitting audio.
