When adjusting the sensitivity level of the inputs, keep in mind that the instantaneous
modulation level is given in the predefined menu and that an indicator signals the
75 kHz level. To get a proper adjustment, we recommend you put a level signal on
the machine’s output equivalent to the level of its own audio program and adjust
the relative trimmer until the instantaneous deviation coincides with the indication
of 75 kHz.
To adjust the levels of the inputs of the subcarriers, you can use a similar procedure
while getting help from the “x10” option that can be selected from the “Fnc” menu.
With this option, the modulation level indicated is multiplied by a factor 10 so the
drawn indication of the predefined menu coincides with a deviation value of 7.5
kHz.
There is a special menu in which the levels of the Right and Left channels are
indicated separately with the relative indicators of the nominal levels for the
maximum deviation of 75 kHz.
