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 different formats. With both inputs and outputs for coaxial and optical connections, it provides the perfect solution for audio conversion applications.
