Am I In Phase?
If your inputs are out of phase and you turn the balance control
of your radio all the way to one side, right or left, the bass output
from the Bazooka
®
will increase. When you bring the balance
control back to the center position the bass level will drop. This
confirms that one of your input channels is wired out of phase
with the other.
When one of the Amplified Bazooka's High-level Input channels
is out of phase electrically with the other High-level Input channel,
your Bazooka will sound as if it has little or no output and any
output that is produced may sound distorted. If you suspect that
your Bazooka is out of phase, use the AM I IN PHASE procedure
to diagnose and correct the Bazookas' output, and proper bass
response will be produced. channels is wired out of phase with
the other. To correct this situation, simply flip the phase switch
on the amplified Bazooka
®
. When the input signal is in correct
electrical phase, the level of bass output will be greatest when
the balance control of the radio is set to the center position.
Do You Have A Phase Problem?
If the bass response in your application appears to be lower then
you expected or sounds muffled and or distorted, you may be
experiencing Phase Cancellation.
Phase Cancellation
When two speakers in the same frequency range produce sound
waves that are inverted from one another or 180° out of phase,
the sound waves will cancel each other out to some degree. This
effect will be heard as a drop in the output level and/or a muffled
or muddy quality in the Bass Response. The source of this Phase
Cancellation can be at any point in the signal path. The obvious
cause of this problem would be a speaker connection that was
reversed in polarity, but that is not always the case. Sometimes
amplifier channels will shift phase 180° for no good reason, or
a signal processor could have a setting for phase that has been
set incorrectly or the source material could just be recorded in
error. Also speaker placement and the acoustics of the listening
environment can effect the phase. No matter what or where the
cause is located, the solution is an easy one.

Remote Bass Control and Crossover (RBCM-RS):
If you find you like to vary the crossover point in addition to changing
the level of bass depending on what you are listening to and want an
easy way to make this possible, you can purchase an optional Remote
Level and Crossover Control.
These Remote Controls are accessories that are available from your
Bazooka dealer or directly from Bazooka. Be sure to check out other
optional accessories for your Bazooka at

On the back of all Bazooka El and Marine passive models you will find
a terminal cup with two spring loaded terminals, red being positive
and black being negative. Hook the positive speaker output from your
amplifier to the red positive terminal of the Bazooka. Hook the negative
speaker output from your amplifier to the black negative terminal.
Repeat these steps for each Bazooka used.
