Variable de-emphasis output
pin.
(Connect a 4.7µF non-polar
capacitor between Pins 34
and 35.)
VCA input pin.
Input the variable
de-emphasis output signal
from Pin 34 via a coupling
capacitor.
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.)
