Muting Function (pin 1)
By means of controlling pin 1 less than 0.5 V, it can make the audio muting condition.
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 15 k, we recommend 10 k.
The muting function have to be controlled by a transistor, FET and -COM port which has IMUTE >
250 A ability.
pin 1 must not be pulled up and it shall be controlled by OPEN/LOW.
