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DAC内部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5。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。)
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。
注: 这个选项用于匹配不同的I2S接口标准, 使用前请检查信号源的接口定义。

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!
