1. Introduction
Thank you for choosing the Liberty DAC from Mytek Digital and welcome to the Mytek users’ community.
Over 20 years of experience in building mastering grade converters and other audio equipment has
been utilized to create this digital to analog converter. Its sophisticated audio path is designed to
deliver bit perfect, high quality, transparent sound to your speakers and headphones. Liberty DAC will
play:
• PCM up to 32 bit / 384 kHz.
• DSD64, DSD128, DSD256
• MQA master quality les o online streaming services.
• Any other digital source equipped with USB, Toslink, SPDIF or AES.
• Any other analog source plugged into analog input.
The Liberty DAC has been optimized for highest performance under Windows, Mac OS and Linux.
Based on a newly developed Mytek Hi-Speed USB (USB2) Audio Class 2 32bit / 384kHz Integer
Interface, the LibertyDAC provides very low latencies as well as extreme stability.
Mytek provides Windows (up to Win10) 32 bit drivers, both WASAPI and ASIO (with native DSD)
developed by Thesycon.com. Mac OSX and Linux computers as well as the Linux audio streaming
devices do not require a driver.
Enjoy your new Liberty DAC!
All the best,

8. MQA - Master Quality Authenticated
Liberty DAC+ includes MQA technology, which enables you to play back MQA audio les
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 – MQA valid, the MQA is detected
• Blue. – MQA authored, the MQA is detected and the le 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 le that is small and convenient to download or even
stream. There are no sonic sacrices that are usually associated with compressed les. What this
basically means is that high resolution audio streaming could nally 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 le into the sort of space needed
for a 24-bit / 44.1KHz stream. In practice, MQA is delivered to listeners as a typical lossless le, such
as FLAC or Apple Lossless at 44kHz or 48kHz at 24 bits.
