Using a Real Time Audio Analyzer (RTA)
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 system
long enough, it will actually start sounding
pretty good. Only later, when your hearing
"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 autho-
rized AudioControl dealer about this professional
sound-balancing option.
