FUNCTION DESCRIPTION
MUTE AND STAND-BY FUNCTION
The pin 5 (MUTE/STAND-BY) controls the amplifier status by two different thresholds, referred to +Vs.
- When Vpin5 higher than = +Vs - 2.5V the amplifier is in Stand-by mode and the final stage generators are
off
- When Vpin5 is between +Vs - 2.5V and +Vs- 6V the final stage current generators are switched on and the
amplifier is in mute mode
- When Vpin5 is lower than +Vs - 6V the amplifier is play mode.
