11.  Using either a Real Time Analyzer (blatant plug for

AudioControl products) or just your ears, if there are no other
options, adjust the output levels on your MVC to balance the
sound of your system.  You will want an equal amount of
bass, midbass, midrange, and high frequencies.  Try not to
increase or “boost” the output controls of the quieter
amplifiers but decrease or “cut” the louder amplifiers.

12. You will have achieved optimum level settings (aka

audio nirvana) for your system when the volume control for
the MVC is maximized and the amplifiers are just starting to
clip.  If you have a different experience, see the section on
troubleshooting.

7.  Check your amplifiers owner’s manual or on the unit

itself to determine the highest voltage of signal you can send
in to your amplifier.  (If you are still dancing from the
previous step, you may now stop!)

8.  Adjust the output level controls on your MVC until the

voltage indicator LEDs are flashing at the maximum signal
voltage level your amplifier can handle.

9.  Reduce the volume on your MVC dash control, but

don’t touch your source unit.  Set the gains on your amplifi-
ers at the highest input voltage setting.  In some this means
turning the gain controls counter-clockwise also known as
“turning them down”.

10.  Connect the RCAs between the MVC and your

amplifier(s) and raise the signal level, using your MVC, to a
medium level.
