DIRAC LIVE
The proprietary Dirac Live is integrated with your M33. Dirac Live® is a
patented room correction technology that not only corrects the frequency
response, but also the impulse response of a room’s loudspeakers. Dirac
Live provides true impulse response correction over a large listening area,
improving the depth, positioning and distinction of individual voices and
instruments. Using multiple measurement and mixed phase correction,
Dirac Live helps create a natural, realistic and transparent sound with
tighter bass and reduced room modes, in a way previously not possible.
Initiate Dirac Live by following below Setup Requirements.

MASTER QUALITY AUTHENTICATED
Master Quality Authenticated
(MQA) is a revolutionary end-to-
end technology built into M33 that
captures and delivers master quality
audio. M33 includes a powerful
decoder and audio renderer for the MQA system. This ensures that MQA-
encoded audio files sound exactly like the source.
In the BluOS app, the MQA indicator displays green or blue to indicate that
the unit is decoding and playing an MQA file. It displays green to indicate
decoding and playback of a MQA file and denotes provenance to ensure
that the sound is identical to that of the source material. It displays blue to
indicate playback of MQA Studio file that has either been approved in the
studio by the artist/ producer or has been verified by the copyright owner.
MQA® is a trademark of MQA Limited.
MAKING THE MOST OUT OF YOUR M33
