MQA (Master Quality Authenticated)
MQA 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.
Visit mqa.co.uk for more information.
Pro-Ject Pre Box RS2 Digital includes MQA technology, which enables you to play back MQA audio files and
streams, delivering the sound of the original master recording.
'MQA' indicates that the product 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. 'MQA' indicates 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.
