HDMI Audio Extraction for 4K@30Hz Sources

The ESTONE HDMI Audio Extractor splits a single HDMI input into a pass-through HDMI output plus optical TOSLINK and analog RCA stereo outputs. It is designed for users who need separate audio feeds from devices such as game consoles, streaming sticks or set-top boxes while keeping the video signal intact.

5.1CH Optical and 2CH Analog Output Modes

The optical SPDIF port delivers 5.1CH Dolby Digital and DTS bitstreams, though Dolby Digital Plus is not supported. The analog RCA L/R output provides 2CH PCM stereo only. Three audio mode selections — Pass, 2CH and 5.1CH — let you match the output to your amplifier or soundbar.

49ft Transmission Limit with AWG26 Cable

Video input resolutions up to 3840x2160@30Hz and 4096x2160@30Hz are supported with 24, 30 and 36 bit deep colour. The converter maintains signal integrity for distances up to 49ft when used with AWG26 HDMI cable. PS3 5.1CH output is not supported, and no HDMI 2.0 bandwidth or higher refresh rates are available.

Questions about this item

Will this extractor pass 4K at 30 Hz to my older 1080p display while sending 5.1-channel audio to my receiver?

Yes, the unit accepts up to 3840x2160@30Hz and 4096x2160@30Hz input and provides simultaneous HDMI, optical TOSLINK SPDIF and analog RCA outputs.

How do I know the box is powered and linked to my TV once cabled up?

A red LED lights when power is on; a green LED lights when the HDMI output detects a connected display.

Does the package include the HDMI and optical cables I need, or must I supply them?

Only the converter unit and its power supply are included; HDMI cables, a TOSLINK optical cable and RCA leads must be purchased separately.
