The MQA indicator LED on the front panel of the DacMagic 200M will indicate when an MQA file is being processed.
Signifies the output as an MQA File. This indicates that a full decode is being performed by the 200M.
Signifies MQA Studio. Approved in the studio by the artist/producer or verified by the copyright holder as accurate to the original recording. This indicates that a full decode is being performed by the 200M.
The MQA stream is pre-decoded and the unit is operating as a renderer; this means that the unit is outputting a stream that has been decoded by the TIDAL app. Although this is perfectly fine, a better solution is to enable the 200M to execute a full decode. To do this, turn on MQA passthrough in your TIDAL settings to allow the DacMagic 200M to complete the unfolding process rather than the source device (e.g.: the computer).
