Fast muting

Fast muting

The muting time can be shortened to less than 1.5ms by setting (IB2) D5 = 1. This option

can be useful in transient battery situations (i.e. during car engine cranking) to quickly

turnoff the amplifier for avoiding any audible effects caused by noise/transients being

injected by preamp stages. The bit must be set back to “0” shortly after the mute transition.
