HDMI audio extractor for 4K sources

The ESTONE OZV8 splits one HDMI input into a mirrored HDMI output plus separate optical SPDIF and 3.5 mm analogue audio. It handles video up to 4K at 60 Hz with 18 Gbps bandwidth and deep colour up to 36 bit. A three-position EDID switch selects pass-through, stereo or 5.1-channel audio modes. The unit ships with a 5 V power adapter and a short HDMI cable.

Passive cooling and low power draw

The aluminium enclosure dissipates heat without a fan, so operation is completely silent. Maximum working current is 350 mA from the included 5 V supply, keeping energy use minimal. No driver installation is required, and the extractor adds no measurable latency to the video path. The compact 5.59 by 3.15 by 1.26 inch form factor fits behind most displays or AV racks.

Stable signal under continuous use

The 340 MHz pixel clock and 18 Gbps throughput are maintained during extended playback sessions without signal drop-out or HDCP handshake loss. Both SPDIF and 3.5 mm outputs remain active simultaneously, allowing a soundbar and headphones to run in parallel. The device does not support Bluetooth headsets and cannot accept an AV receiver as the HDMI source.

Questions about this item

How do I install the ESTONE OZV8 and which EDID switch position should I choose?

Connect the source to the HDMI IN port, the display to the HDMI OUT port, and attach the supplied 5 V/1 A power adapter; then set the 3‑position EDID switch to Pass, 2CH or 5.1CH to match your audio system.

What maintenance will the ESTONE OZV8 require over time?

No routine maintenance is needed; keep the unit ventilated, check that the power adapter and cables remain firmly seated, and replace the 5 V/1 A supply only if it fails.

What is the first limit I will hit when running 4K@60 Hz content continuously?

The 18 Gbps bandwidth ceiling and 350 mA current draw are the primary limits; ensure both source and display support 4K@60 Hz simultaneously to avoid signal dropouts.
