3. Muting function
4. AUX. input
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 R
ON/OFF.The series resistance; R
The muting function have to be controlled by a transistor, FET and µ-COM port which has I
ability.
Terminal 24 must not be pulled up and it shall be controlled by OPEN/LOW.
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.
