A : MUTE period (use with MUTE
=
Low to prevent the popping noise when the power is turned on and off).
B : MUTE release time (used to prevent the popping noise at the release of MUTE with the external C2 and R2,
and therefore possesses a time constant, so be careful of the timing).
C : MUTE start time (also possesses a time constant like the MUTE release time).
