MUTE/STAND-BY FUNCTION
MUTE/STAND-BY function is assembled at pin 5 and to control 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.
