3 MUTE STAND-BY FUNCTION
The pin 5 (MUTE/STAND-BY) controls the amplifier status by two different thresholds, referred to +V
S
.
– When V
pin5
higher than = +V
S
-2.5V the amplifier is in Stand-by mode and the final stage generators
are off.
– When V
pin5
between = +V
S
-2.5V and V
S
-6V the final stage generators are switched on and the am-
plifier is in mute mode.
– When V
pin5
lower than = +V
S
-6V the amplifier is play mode.
