VCA input pin.
Input the variable
de-emphasis output signal
from Pin 29 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 3.9k resistor in series
between this pin and GND.)
Right channel external input
1 pin.
Left channel external input
1 pin.
Right channel external input
2 pin.
Left channel external input
2 pin.
