and streams, delivering the sound of the original master recording. MQA content is detected
automatically and colour of MQA / DSD led indicates what type of MQA is detected.
• Green

• Blue.
– MQA authored, the MQA is detected and the file is fully authenticated. You can be sure
you are hearing exactly what the artist approved in the studio
What is MQA?
MQA is audio recording and compression format created by Meridian Audio. It is also a new sophisticated
method of digitally storing recorded music as a file that is small and convenient to download or even
stream. There are no sonic sacrifices that are usually associated with compressed files. What this
basically means is that high resolution audio streaming could finally be a reality, with songs being
able to be delivered exactly how they were recorded in the studio, without requiring huge amounts of
bandwidth to deliver.
How does MQA work?
MQA can pack up the information from a lossless 24-bit 192kHz PCM file into the sort of space needed
for a 24-bit / 44.1KHz stream. In practice, MQA is delivered to listeners as a typical lossless file, such
as FLAC or Apple Lossless at 44kHz or 48kHz at 24 bits.
