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。 SU-9 PRO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
SU-9 PRO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。
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

这个DPLL设定是ESS系列产品特有的功能, 它可以调整芯片内部DPLL数字锁相环电
路的带宽, 使芯片在抗时钟抖动和输入宽容度之间达到一个平衡。
它的作用:
在输入信号的时钟稳定度好的情况, 可以减小这个值, 这样系统的时钟性能更佳;
在输入信号的时钟稳定度不好的情况下, 声音有可能会有中断的现象, 增大这个
值可以避免声音中断现象的发生! 特别是使用电视作为信号源时。

Operating the remote control
Note
This remote controller use 2 x R03/AAA batteries.
Remote control
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.

Connection:
Step 1: Switch the input source in the SETTING MENU or press the Bluetooth button of the remote;
Step 2: Turn on the Bluetooth function of the mobile phone, search for "SMSL SU-9 PRO", and tap to
pairing. When the mobile phone displays "connected", it has been successfully connected.
Re-connection:
When you had lost the connection with the SU-9 PRO, for example,going out,and back home, some
phones will not re-connect the SU-9 PRO if the SU-9 PRO has not been re-boot, so you can press the
Bluetooth button on the remote to Re-connect.
Clear pairing: Long press the "Bluetooth" button on the remote control. After clearing the pairing, some
phones may no longer be able to search for "SMSL SU-9 PRO". In this case, you need to delete the
Bluetooth device "SMSL SU-9 PRO" which saved in the phone, and then search and pairing again.

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 SU-9 PRO 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-9 PRO'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-9 PRO 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.
and the Sound Wave Device are registered trade marks of MQA Limited.© 2016

DPLL
MIN ~ MAX
(A total of 15 kinds, the default is 7 kinds. The larger the number is, the stronger
the range to adapt to jitter, and the smaller the number, the better the performance
against clock jitter.)
This DPLL setting is a special function of ESS series products. It can adjust the
internal DPLL digital phase locked loop circuit Bandwidth, so that the chip
achieves a balance between anti clock jitter and input tolerance.
Its function:
When the clock stability of the input signal is good, this value can be reduced,
so that the clock performance of the system is better;
When the clock stability of the input signal is not good, the sound may be inter-
rupted. Increase this value can avoid the sound interruption! Especially when
using TV as signal source!
