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。 M500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
M500只有USB接口支持MQA解码,其它接口不支持!
M500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。
MQA商标旁边的指示灯为绿色或蓝色亮起，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。 它呈蓝色亮起，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.当MQA商标旁边的指示
灯发出红色，表示该机器正在发送MQA音频或文件，这就是MQA文件的最后一步。
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

Note
Firmware and driver download:
http://www.smsl-audio.com/cn/download.asp
Install 2 x AAA batteries as instructions.
When using the remote control, point it toward the remote con-trol signal receiver on
the main unit from a distance of 5 m (16 ft) or less. Do not place obstructions between
the main unit and the remote control.
The remote control might not work if the remote control signal receiver on the unit is
exposed to direct sunlight or bright light. If this occurs, try moving the unit.
Beware that use of this remote control could cause the unin-tentional operation of
other devices that can be controlled by infra.

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 M500 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.
The M500 supports MQA decoding on the USB interface.
M500'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 M500 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.The M500 LED next to
MQA logo glows magenta to indicate that the unit is rendering an MQA stream or file.
This delivers the final unfold of the MQA file.
When playing an MQA file, the sampling rate of the original master recording is
displayed.
