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 = +VS - 2.5V the amplifier is in Stand-by mode and the final stage generatorsare off
- when V
pin5
is between +VS- 2.5V and+V
S
- 6V the final stage current generators are switched on and the amplifier is in mute mode
- when V
pin5
is lower than +VS - 6V the am-
plifier is play mode.
