HDA-939 is a professional-grade audio and video processor designed to extract and downmix HDMI audio for maximum flexibility. It supports decoding of Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, and DTS-HD Master Audio and outputs 2CH LPCM through analog, coaxial, and optical ports. HDMI OUTPUT 1 supports video resolutions up to 4K@60Hz 4:4:4 with automatic downscaling to 1080p, while HDMI OUTPUT 2 serves as an audio-only output delivering high-bandwidth audio to traditional AVRs. ARC/eARC functionality allows audio to be returned from a connected TV and routed to external sound systems. Audio can be extracted without connecting any HDMI display. With advanced EDID management, API command support, DIP switch settings, and simultaneous multi-port audio output, the HDA-939 is ideal for modern AV setups requiring precise audio routing, downmixing, and video compatibility.
