Weight the variable de-
emphasis control effective
value detection circuit.
(Connect a 0.047 µF
capacitor and a 3 k
resistor in series between
this pin and GND.)
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 23 and 24.)
VCA input pin.
Input the variable de-
emphasis output signal
from Pin 23 via a coupling
capacitor.
