The AU-1H1DD-4K22 is an advanced solution for de-embedding and down-mixing audio signals from the HDMI input (up to Dolby, Digital and DTS, 2.0+Digital Out). Connect the AU-1H1DD between the source and your display via HDMI, and select 2CH LPCM or bypass. The digital audio outputs can be set to either 2CH LPCM or bypass. The L/R analogue outputs will always output down-mixed stereo (with audio up to Dolby, Digital and DTS, 2.0+Digital Out). This device supports the latest 4K2K resolutions, HDMI2.0 and HDCP2.2 for stunning results.
