What this device does

The ESTONE OZV8-2 takes one HDMI source and splits the signal into an HDMI output with ARC plus separate optical SPDIF, stereo RCA and 3.5 mm analogue audio connections. It is built for installers or home-theatre owners who need to feed a soundbar, AV receiver or headphones while keeping the video path intact.

Bandwidth and cable limits

The extractor handles a maximum bandwidth of 600 MHz and 18.5 Gbps, supporting 4K at 60 Hz with YUV 4:4:4 colour sampling. HDMI cables up to 10 metres using AWG26 2.0a standard wire are specified for both input and output runs; longer or thinner cables may not pass the full signal.

The deciding specification

If your source and display both require HDCP 2.2 for protected 4K content, this unit meets that requirement. Buyers who need to extract audio from a non-HDCP stream or who only have legacy 1080p gear will still find it functional, but the HDCP 2.2 ceiling is the feature that determines whether it fits a modern 4K chain.

Questions about this item

Should I choose the version with both SPDIF and 3.5mm outputs or just one of them?

This model provides both SPDIF and 3.5mm jack outputs simultaneously alongside the HDMI ARC port, so you do not need to choose between them.

What does the 18.5 Gbps bandwidth figure mean when I connect a 4K 60Hz source?

The 18.5 Gbps maximum baud rate carries the full 4K 60Hz YUV4:4:4 signal with HDR10 and Dolby Vision without compression.

How does the HDMI 2.0b interface limit the audio formats I can extract?

The HDMI 2.0b link supports up to 7.1-channel LPCM and bitstream formats such as DTS-HD and Dolby TrueHD, which are then split to the SPDIF and 3.5mm outputs.
