MOD IN
Modulator input from an external terminal unit.
Input impedance: 2.7 k
Ω
Input level: 85 mV rms (for 60% deviation)
NOTE: If the input impedance is changed
to 27 k
Ω
, a 300 mV rms input level is
needed for 60% deviation signal.
9
DISC OUT
Buffer output terminal for AF signals from the AF detector
circuit. The output level simultaneously changes with the
modulation level of the received signal, regardless of the
[AF] control setting.
Output level: 300 mV rms*
