This Audio Decoder supports the transmission of high bandwidth (18Gbps) video and allows the associated audio signal to be simultaneously extracted and split to both digital and analog audio outputs, providing high quality audio and video performance.
This unit can decode standard Dolby Digital & DTS formats up to 5.1 and output the audio as stereo (LPCM 2.0) over HDMI, S/PDIF (optical and coaxial) and analog RCA connections. It can also support the passthrough of Bitstream, HD Bitstream, or LPCM 7.1 with audio sampling rates up to 192kHz if needed. If the connected display supports ARC (Audio Return Channel), and has it enabled, then this unit can extract the ARC audio and output it via all available audio outputs.
Both the input and output HDMI ports support 4K UHD resolutions up to 4K@60Hz (4:4:4, 8-bit). Built-in EDID management support allows the user to select from multiple EDIDs and, with the use of optional PC software, to upload, download, or edit EDID files.
