Determine the restoration
time constant of the VCA
control effective value
detection circuit.
(the specified restoration
time constant can be
obtained by connecting a
10µF capacitor between this
pin and GND.)
Weight the VCA control
effective value detection
circuit.
(Connect a 1µF capacitor
and a 3.9kΩ resistor in series
between this pin and GND.)
