Muting Function (pin 22)
The muting time constant is decided by R1 and C4 and these parts is related the pop noise at power
ON/OFF.
The series resistance; R1 must be set up less than 10 k.
The muting function have to be controlled by a transistor, FET and
-COM port which has IMUTE > 250
A ability.
Terminal 22 must not be pulled up and it shall be controlled by OPEN/LOW.
