The AU-11PRO is a Audio Extractor & Inserter that can take the selected audio from an HDMI, ARC (from HDMI Output 1), optical, or analogue source and output it simultaneously over the unit’s HDMI, optical, and analogue outputs. This allows the user to convert an audio source using high quality ADC/DAC processing for use with powered speakers or an AV receiver that otherwise would not be able to support the original format. The HDMI input and mirrored HDMI output ports support resolutions up to 4K@60Hz (4:4:4, 8-bit) and advanced video content such as HDR (High Dynamic Range), 10-bit color is also supported. The built-in EDID management controls allow the user to select from multiple pre-configured EDIDs, including the option for a custom user uploaded EDID.
