Determine the restoration time
constant of the variable de-
emphasis control effective
value detection circuit.
(The specified restoration time
constant can be obtained by
connecting a 3.3 µF capacitor
between this pin and GND.)
Variable de-emphasis output
pin.
(Connect a 4.7 µF non-polar
capacitor between Pins 33
and 34.)
VCA input pin.
Input the variable de-
emphasis output signal from
Pin 33 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 10 µF capacitor
between this pin and GND.)
