关于MQA
MQA文件播放
MQA（Master Quality Authenticated）是一项屡获殊荣的英国技术，
是一种兼有极高的采样率和足够小的文件体积的高解析音频编码技
术。 此机采用MQA技术，可以接收并解码MQA音频，提供母带级别的
声音。
有关更多信息，请访问https://www.mqa.co.uk/how-it-works
此机的MQA播放不要求使用特殊的播放软件，例如foobar2000，
Audirvanaplus只要 支持ASIO或者WASAPI的音频输出就可以了
，并且在播放MQA音频时，最好将电脑的音量调到最大，以使得电
脑的音频输出是最佳状态。
在播放MQA文件时， 显示屏显示的采样率为音频原始采样率。
和声波标志是MQA Limited的注册商标。©2016

About MQA
MQA files playback
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. The machine includes MQA technology, which enables you to
playback MQA audio files and streams, delivering the sound of the original
master recording.
Visit How it works https://www.mqa.co.uk/how-it-works for more
information.
SU-1's MQA playback does not require additional software. You can
use foobar2000 or Audirvana for MQA playback as it supports ASIO
or WASAPI audio output. When playing MQA audio, it is suggested to
adjust the volume of the computer to the maximum for the best audio
output.
The SU-1 LED next to MQA logo glows green or blue to indicate that
the unit 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. It glows blue to indicate 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.
When playing an MQA file, the sampling rate of the original master
recording is displayed.
