MUTE STANDBY FUNCTION The pin (MUTE/STANDBY) controls the amplifier status by two different thresholds, referred to V S. hen Vpin higher than = VS.Vthe amplifier is in Standby mode and the final stage generators are off Figure when Vpin is between VS.V and VS V the final stage current generators are switched on and the amplifier is in mute mode when Vpin is lower than VS V the amplifier is play mode.
