Standby switch and muting switch usage methods (for reference purposes)
(1) The amplifier will be on when the standby switch (pin 4) has a voltage of 2V or higher applied, and will be off when
that pin is at the ground level.

(2) Muting will be on when muting switch (pin 22) has a voltage of 1V or lower applied, and will be off when that pin
is open
