NFB-17.32
分立件平衡DAC

32bit / 384K 异步传输 USB-32 芯片
两片Hi-end级WM8741芯片


售价:    RMB 2850 (含国内与香港运费及运输保险)

                  

        
概述 使用指引 规格 技术细节 定制选项

请注意开关机的原则:
开机:
     信号源开机 -----
> NFB-17 开机 -----> 放大器开机 (耳放,前级,合并机等)
关机:
    放大器关机 (耳放,前级,合并机等)-----> NFB-17 关机 ---->信号源


OS 按钮:设置NFB-17 的数字滤波器 采样率为2倍或4倍或8倍。
 

Filter 按钮:设置NFB-17 的数字滤波器 三种特性。

Selector 按钮:  选择NFB-17的输入方式: 显示为1:USB1输入。 显示为2:同轴2输入。 显示为3:同轴3输入。显示为4:光纤4输入。显示为5:光纤5输入 。
