4.
Pop Noise Suppression
The pop noise which is generated when the muting function is turned ON/OFF will vary according to the
time constant of C4.
The greater the capacitance, the lower the pop noise. Note that the time from when the mute control
signal is applied to C4 to when the muting function is turned ON/OFF will be longer.
