About MQA
MQA files playback
MQA (Master Quality Authenticated) is an award-winning British technology that delivers the
sound of the original master recording. The master MQA file is fully authenticated and is
small enough to stream or download. The D12 includes MQA technology, which enables you
to playback MQA audio files and streams, delivering the sound of the original master
recording.
Visit How it works https://www.mqa.co.uk/how-it-works for more information.
D12's MQA playback does not require additional software. You can use foobar2000 or
Audirvana for MQA playback as it supports ASIO or WASAPI audio output. When playing
MQA audio, it is suggested to adjust the volume of the computer to the maximum for the
best audio output.
The D12 LED next to MQA logo glows green or blue to indicate that the unit is decoding
and playing an MQA stream or file, and denotes provenance to ensure that the sound is
identical to that of the source material. It glows blue to indicate it is playing an MQA
Studio file, which has either been approved in the studio by the artist/producer or has
been verified by the copyright owner.It glows magenta to indicate that the unit is
rendering an MQA stream or file. This delivers the final unfold of the MQA file.
When playing an MQA file, the sampling rate of the original master recording is
displayed.
