3. Muting function (pin 24)
By means of controlling pin 24 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 kΩ, we recommend 10 kΩ.
The muting function have to be controlled by a transistor, FET and µ-COM port which has IMUTE ≥ 250 µA
ability.
Terminal 24 must not be pulled up and it shall be controlled by OPEN/LOW.

4. AUX. input (pin 16)
The pin 16 is for input terminal of AUX. amplifier.
The total gain is 0dB by using of AUX. amplifier.
Therefore, the µ-COM can directly drive the AUX. amplifier.
BEEP sound or voice synthesizer signal can be input to pin 16 directly.
