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 authen-
ticated and is small enough to stream or download.
Visit mqa.co.uk for more information.
The VRDS-701 includes MQA technology, which enables you to play
back MQA audio files and streams, delivering the sound of the origi-
nal master recording.
'MQA' or '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.
o When conducting MQA decoding of signals from COAXIAL or
OPTICAL sources, signals need to be received as bit-perfect. So,
use this function with CLOCK SYNC set to OFF unless the digital
audio output device and this unit are synchronized by the same
external clock, in which case set CLOCK SYNC set to ON. If set to
ON when the other digital output device is not clock synchro-
nized, audio skipping and dropouts could occur.
