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。A20d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
A20d只有USB接口支持MQA解码，其它接口不支持!
A20d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。
当显示屏的“ ”或“ ”亮起，表示设备正在解码并播放MQA音频或
文件，并且确保输出音质与源素材一致。它呈“ ”亮起，表示它正在播放
MQA Studio文件，该文件已经由艺术家/制作人或者版权所有者获得授权。
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
