[Input selector switching sequence]
The input selector should be changed after soft mute to avoid the switching noise of the input selector (Figure 22).
MS0427-E-02
The period of (1) varies in the setting value of DATT. It takes 1028/fs to mute when DATT value is +24dB.
When changing channels, the input channel should be changed during (2). The period of (2) should be around 200ms
because there is some DC difference between the channels.
