Fig1. Reference & all mute function
Fig2. Mute function
As shown in figure 1,
Pin#23 is a negative input of the comparator,
and the other Input is the 1.0V reference.
If the voltage of the pin#23 falls below 1.0V,
TR Q1 will be turned on and the output bias current
will be shut down
As shown in figure 2,
Pin#7 is a base input of the TR Q2.
If the voltage of the pin#7 is low or open,
TR Q2 will be turned off and TR Q3 will be turned on,
so the bias current will be shut down by TR Q3.
If the voltage of the pin#7 is high,
the bias circuit operates normally.
