PRE MODE为输出接口的音量调节功能开关：
VARIABLE : 输出接口音量是受控的。
FIXED : 禁用音量调节功能, 使音量保持在当前的值。
FIXED DSD BYPASS : 打开DSD直通功能, 此时播放PCM或者DSD音量都不可调, 输出幅度固定为3.7
Vrms左右, 此功能打开时,DSD完全没有经过处理, 直接输出。

此机的USB、光纤、同轴支持MQA解码！
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
关于MQA
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。

如何播放MQA
播放MQA-CD注意事项
必须确认所播放的是一张真正的MQA-CD ;
确认CD播放器所输出的光纤或者同轴信号是未经处理的源码 。

PRE MODE
PRE MODE is the volume adjustment function switch for the output.
VARIABLE : The output volume is controlled.
FIXED : Disable the volume adjustment function to keep the volume at the current value.
FIXED DSD BYPASS : Open the DSD direct access function. At this time, the volume of PCM or DSD is not
adjusted. The output amplitude is fixed to about 3.7VRMS. When this function is opened, the DSD is not
processed at all, and the output is directly output.
