请注意开关机的原则：
开机：
信号源开机 -----> NFB-3 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-3 关机 ---->信号源关机

Flavor 按钮：改变NFB-3.33 的数字滤波器设置。

ACSS/RCA 按钮:
选择NFB-3.33的内部信号配置。显示为1时信号配置为CAST 输出，显示为2时信号配置为RCA输出。无论在任何配置下，CAST及RCA 均可输出信号到后端放大器，阻碍 CAST连接到CAST放大器并在播放中，RCA 信号些时会被自动静音。
　

Selector 按钮:
选择NFB-3.33的输入方式：显示为U：USB输入。显示为C：同轴输入。显示为O：光纤输入。
