Playing MQA files
MQA (Master Quality Authenticated) 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 www.mqa.co.uk for more information.
The MQA logo is a trademark of MQA Limited and is used under licence.
The Bartók DAC features a full MQA decoder.
MQA files streamed bit-perfect via the Network (for example from Tidal Masters) or
USB2 interfaces will be unfolded and rendered to the original sample rate. The standard
MQA icon will appear on the display, together with the decoded sample rate.
This logo is displayed when an MQA studio file is being played.
MQA data that has been unfolded by another device to 24/88.2 or 24/96 and is presented bit-perfect to
the USB1, AES or SPDIF interfaces will also be rendered to the original sample rate.
When performing MQA playback, the type of MQA stream is indicated on the control app’s Now
Playing screen:
This green-dot icon appears when standard MQA files are being played.
This blue-dot icon appears when MQA studio files are being played.
MQA decoding is not possible if the original MQA data has been changed.
If the MQA logo does not appear when expected, please disable any DSP features in the
streaming program.
