(Affects all amplifier outputs, Amp 1 to Amp 8).
(When the mute voltage is low, the outputs turn off;
when the mute voltage is high, the outputs turn on).
5.0 V regulator built in (Uses external PNP transistor).
Reset circuit built in (The reset output delay time can be
adjusted through an external capacitor).
