Notes: Standby
1.
Power is turned on when a signal of
3.5 V or 0.05 mA is impressed at pin 2.
When pin 2 is open or connected to
GND, standby is turned on (output off).
Muting
2.
Muting is turned off (output on) when
a signal of 3.5 V or 0.2 mA is impressed
at pin 10.
When pin 10 is open or connected to
GND, muting is turned on (output off).
