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 M500 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.
The M500 supports MQA decoding on the USB interface.
M500'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 M500 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.The M500 LED next to
MQA logo 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.
