N o t e : 1. Standby

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 tumed on (output off).

2. Muting Muting is turned off
(ourput 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).
