HDMI Audio Extraction

The ESTONE OZV8C takes a single HDMI source and splits the signal into one HDMI video output plus separate optical Toslink and 3.5 mm analogue audio outputs. It is intended for users who need to feed a soundbar, amplifier or headphones while keeping the display connected. The unit handles 4K at 60 Hz and passes 3D content with HDCP 1.4 compliance.

Sustained Signal Handling

The extractor maintains an 18 Gbps bandwidth path so 3840 x 2160 resolution at 60 Hz remains stable during extended viewing sessions. Three selectable audio modes — TV, 2.0 CH and 5.1 CH — let the user match the output to the connected audio system without signal dropouts. Supported digital formats include DTS-HD, Dolby TrueHD and LPCM 7.1 for continuous multi-channel playback.

Build and Connectivity

A compact black enclosure measuring 5.59 x 3.15 x 1.26 inches and weighing 3.2 ounces fits easily behind a display or inside a rack. The package includes a 5 V power adaptor, ensuring reliable operation without drawing power from the HDMI source. Optical and 3.5 mm ports can drive separate audio receivers simultaneously, simplifying daily switching between speakers and headphones.

Questions about this item

Does the extractor itself add noticeable heat or fan noise when running continuously?

The unit is passively cooled with no fan, so it runs silently and only becomes slightly warm during all-day use.

Which cables and power source must I already have to connect a 4K source to both a display and a soundbar?

You need one HDMI cable for the source, a second HDMI cable for the display, either a Toslink optical cable or a 3.5 mm stereo cable for the soundbar, and a free mains socket for the included 5 V power adapter.

Will my older 1080p AV receiver still pass video through this splitter at 60 Hz?

Yes, the extractor supports 1080p at 60 Hz and HDCP 1.4, so legacy equipment passes video unchanged while audio is sent separately via optical or 3.5 mm.
