NOTE: If the (yellow) OVERLOAD indicator
comes on, something is boosted too much.
Either bring down the suspect frequency control
or adjust the INPUT GAIN controls to reduce
the overall gain.

For a really well-balanced system, we highly
recommend using a Real Time Analyzer (like
the AudioControl SA-3055) to adjust your
vehicle’s sound system. This tool is especially
helpful in performing the initial adjustments
for multi-amplifier installations.
Balancing a system “by ear” should be per-
formed as fine-tuning after using a Real Time
Analyzer, since our ears adapt very quickly to
any new frequency adjustments.
In fact, if you listen to a badly-adjusted sys-
tem long enough, it will actually start sound-
ing pretty good. Only later, when your hear-
ing “refreshes” and your buddies come to
audition your new system, will you realize
how far off the mark Def Leppard really is!
Now. . . do yourself a big favor and ask an
authorized AudioControl dealer about this
professional sound-balancing option.
