分别为:
47kHz Cutoff (47kHz频率截止)
50kHz Cutoff (50kHz频率截止)
60kHz Cutoff (60kHz频率截止)
70kHz Cutoff (70kHz频率截止)
SOUND COLOR(音色菜单)
本机总共有9种音色模式，它是通过对DAC进行DSP处理，分别为：
Rich1、Rich2、Rich3（泛音丰富）
Tube1、Tube2、Tube3（胆味)
Crystal1、Crystal2、Crystal3（高清晰度）
音色设置是使用ES9038PRO DSP，做出不同的音色效果，所有这些设置不会改变
频率响应曲线。设置为Standard模式将禁用此功能!

(共15种，默认为7。数字越大适应抖动的范围越强，数字越小抗时钟抖动的性能
越好。)
PRE MODE(前级模式)
PRE MODE为输出接口的音量调节功能开关：
Vol Fixed:输出接口音量是固定的。
Vol Variable:输出接口音量是受控的。
功能介绍
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。

NORMAL (普通模式)
PROCESSOR (处理器模式)
SPDIF MODE (处理器模式)
这个设定仅对光纤和同轴这两个使用SPDIF协议的接口有效;
NORMAL模式, 仅使用数字接收芯片对SPDIF信号进行处理, 使用于大部分场合,
在此模式下支持DOP的播放。
PROCESSOR模式, 此模式下本机会使用XMOS处理器对光纤同轴的信号进行处理,
这样可以有强大的算力, 可以处理包括MQA, DOP在内的各种复杂任务, 此时,系统
可以支持MQA全解码,MQA-CD, DOP64。
注意: 使用时请勿频繁切换此模式, 尽可能在切换完此模式后重启本机, 否则可能会
导致输出杂音。

DIMMER (自动熄屏)

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.

Bluetooth operating instructions**
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 M500 MKII",
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 M500 MKII, for example,going out, and back
home, some phones will not re-connect the M500 MKII if the M500 MKII has not been
re-boot, so you can press the Bluetooth button on the remote to Re-connect.
Clear pairing: In the Bluetooth input state, long press the FN button. After clearing the pairing,
some phones may no longer be able to search for "SMSL M500 MKII". In this case, you need
to delete the Bluetooth device "SMSL M500 MKII" which saved in the phone, and then search
and pairing again.
Please turn down the volume before connecting the headphones to avoid excessive volume
damage to the headset.
According to the advice of health experts, do not listen to the headphones for a long time so
as not affect your hearing.

(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.)
Volume control enable or disable.
Vol Fixed : In this mode, volume is fixed on max output level, and the M500 MKII
will ignore the volume operations.
Vol Variable: In this mode, volume can be adjust by remote controller, and make
M500 MKII a pre-amplifier.
PRE MODE
Instructions
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!
M5OO MKII
NORMAL MODE
NORMAL mode, only use the digital receiver chip (DIR) to process the SPDIF signal,
used in most occasions, in this mode supports DoP playback.
PROCESSOR MODE
PROCESSOR mode, in this mode M500 MKII will use the XMOS processor to process the
optical/coaxial signal, so that it can have more powerful computing power and can
handle various complex tasks including MQA, DoP,At this time, the system can support
MQA full decoding, MQA-CD, DoP64.
Note: do not switch this mode frequently, try to restart the machine after switching this
mode, otherwise it may cause output noise.
SPDIF MODE
This setting is only valid for optical/coaxial interfaces which using SPDIF protocol;
