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.
