Pins 55 and 58 include built-in
DC cut capacitors.
The AGC on level is determined
by the values of the capacitors
C1 and C2.

W-AGC IN
AM SD ADJ
Pin 55 functions as the SD
sensitivity adjustment pin in
AM mode.
58
N-AGC IN
Muting attenuation
adjustment pin
The output current I55 is 50 μA,
and V55 varies depending on the
value of the external resistor.
The SD function operates by
comparing V55 with the S-meter
voltage.
