HDMI Audio Extractor with ARC

The ESTONE OZV8-1 splits one HDMI input into a pass-through HDMI output plus optical Toslink and 3.5 mm analogue audio. It handles 4K at 60 Hz, 3D and deep colour up to 36-bit. The unit suits installers who need to feed a soundbar or AV receiver while keeping the video path intact. It requires the included 5 V power adapter to operate.

Plug-and-play with EDID dip-switches

Connect the source, the display and the audio device, then select 2.0 CH, 5.1 CH or Pass mode via the three-position switch. The aluminium shell aids heat dissipation during continuous use. A common issue is forgetting to match the EDID setting to the connected audio gear, which can mute surround formats. Input and output cables up to 10 m AWG26 are supported.

Stable 18 Gbps throughput under load

The splitter maintains the full 18 Gbps bandwidth and 600 MHz pixel clock during extended 4K60 sessions. Maximum working current is 350 mA, well within the supplied adapter rating. Video and audio remain synchronised without dropouts on Blu-ray, console or streaming sources. It does not support Dolby Digital Plus, so users needing that codec must look elsewhere.

Questions about this item

How can I verify the 4K 60Hz video is passing through correctly after connecting the extractor?

Check that your display shows a stable 3840 x 2160 image at 60 Hz with no flicker, and confirm the source device reports 18Gbps bandwidth or deep colour 30bit/36bit in its settings.

What cables and accessories are included versus what I must supply for the HDMI, optical and 3.5 mm connections?

The box contains the extractor, a 5V/1A power adapter and a manual; you must provide an HDMI cable up to 10 m AWG26 for input, another for output, plus a Toslink optical cable and a 3.5 mm stereo cable if you need those audio paths.

Which audio output mode — HDMI pass-through, optical 2.0/5.1 or 3.5 mm 2.0 — should I select for my soundbar or AV receiver?

Use HDMI pass-through for full 7.1 LPCM or bitstream to an AV receiver; choose optical 2.0/5.1 for Dolby Digital, DTS or LPCM 2.0 to a soundbar; select 3.5 mm 2.0 only for analogue stereo devices.
