HDMI Audio Extraction to Analogue and Optical

This new YINGHUA extractor accepts a single HDMI input and splits the embedded digital audio to both a 3.5 mm stereo jack and a SPDIF optical output while passing the video through to an HDMI output. It handles video resolutions up to 4K x 2K at 24, 50 or 60 frames per second along with 1080p, 1080i, 720p and legacy formats. The unit draws up to 190 mA from its micro USB power port.

Installers Needing Simultaneous Analogue

The three-position EDID switch lets you select pass-through, two-channel or 5.1-channel audio extraction including Dolby Digital 5.1 and DTS 5.1, so integrators can feed a soundbar and an AV receiver at the same time. Users who only require HDMI pass-through without any audio breakout or who need multi-channel analogue outputs beyond stereo will not find those functions here.

6.75 Gbps Maximum Bandwidth with Deep Colour Support

The extractor operates at a maximum bandwidth of 6.75 Gbps and supports 24-bit, 30-bit and 36-bit deep colour video formats at a 225 MHz pixel clock. This single specification determines whether the device can carry the full signal from a 4K source without compression or frame-rate reduction.

Questions about this item

What HDMI resolution and colour depth does the extractor pass through to the display?

It passes 4K x 2K at 24, 50 or 60 Hz plus 1080p, 1080i, 720p, 576p, 576i, 480p and 480i with 24, 30 or 36 bit colour.

How do I power the unit and select the correct EDID setting for my sound system?

Connect the Micro USB power port, then use the three-position switch to choose Pass for HDMI audio only, 2CH for stereo on the 3.5 mm and SPDIF outputs, or 5.1CH for Dolby Digital or DTS 5.1 on SPDIF.

Which audio formats can I get from the SPDIF and 3.5 mm outputs after installation?

The 3.5 mm jack always gives stereo analogue. The SPDIF optical port delivers either stereo PCM or 5.1CH bitstream including Dolby Digital 5.1 and DTS 5.1 depending on the EDID switch position.
