The PulseAudio DAC-DD Digital to Analog Converter with Dolby Downmixing
converts either digital coaxial or optical to analog audio via dual RCA stereo
output. Stereo output signals can then be fed to external devices such as an
audio system, recording device, or powered speakers via standard phono style
(RCA) jacks. Features Dolby Digital downmixing that assures full compatibility
with any playback system without having to downgrade the source, especially
helpful when sending the audio source signal to multiple zones with dierent
formats. With both inputs and outputs for coaxial and optical connections, it
provides the perfect solution for audio conversion applications.
