功能介绍

A20d

       Fast Linear     (

快速滚降,线性相位滤波器

       Slow Linear   (

慢滚降,线性相位滤波器

       Fast Minimum(

快速滚降,最小相位滤波器

)

       Apodizing     (Apodizing 

变迹滤波器

)    

       Fast Hybrid    (

混合,快速滚降,最小相位滤波器

)   

       Brickwall       (

矩形滤波器

)

       

PCM FILTER

 (PCM

滤波器

)

       LOW             (

低增益

)

       HIGH            (

高增益

)

       

HPA GAIN

 (

耳机增益

)

DSD FILTER (DSD

滤波器

)

DSD

总共有

4

种数字滤波方式,它的作用是数字

运算的方式把音频外的杂波过滤掉,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

)

SPDIF MODE 

(

处理器模式

)

NORMAL      (

普通模式

)

PROCESSOR  (

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, 

     

PCM

支持

44.1-192KHZ

DOP

支持

DSD64

     

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MQA。

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。
