Note 1
: The SSG signal of 14
.200 MHz, 0 dBu is input from the AN
T
terminal and the audio output of 0
.63 V, 8 ohms is obtained b
y
adjusting the AF GAIN VR
. After then the AF GAIN VR is fixe
d
and the SSG signal levels of each section is plotted so that th
e
fixed level audio output
.
Note 2
:
In the FM mode, this is the signal level to obtain the sam
e
value as the SIN ratio at 0 dBu signal input
.
Note 3
:
The SSG output is measured through 0
.01 uF ceramic capacito
r
(barium titanate capacitor)
.
