Checking the external DC input
level that should be inside the
green area (11.6 V to 13 V).
Note: With both volume and balance
potentiometers set at “0” on their
respective scales, a 1.0 V input signal
at Line A, Line B, Line C or Line D
input connectors will register 0 dB on
the modulometer scale and produce
a
1.0 V output signal at the output
connectors (factory adjusted).

Output level attenuation
The PL-L is factory set to 0 dB
output level (position 2 -3).
If the output level is too high, it
can be attenuated by 20 dB by
moving the 4 jumpers to the
position 1-2 (See figure).
