AU-11CD-4K22 FAQ

What does a HDMI audio de-embedder do?

An HDMI audio de-embedder (sometimes called an HDMI audio extractor) is a device that separates the audio part of an HDMI signal from the video and provide additional audio connectors that output that audio signal. In this case the audio outputs are an Toslink optical digital and a stereo analogue RCA (phono) audio connectors. With this product, as is common with these products, the HDMI signal maintains both the audio and video signals so you do not lose the audio signal from the HDMI output connection.

What audio formats are supported by the AU-11CD-4K22?

The AU-11CD-4K22 has a bypassed HDMI output so no matter what audio format is input this will always be maintained at its HDMI output. LPCM 2CH, Dolby Digital 2/5.1CH & DTS 2/5.1CH can be output via the AU-11CD-4K22's Toslink S/PDiF optical audio output whilst an analogue stereo signal is output via the L/R RCA (phono) connections.
