TROUBLESHOOTING

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.

PHASE CORRECTING PROCEDURE

Disconnect all but one Bazooka

®

 from your system. Be sure

that any loose wire connections are insulated to avoid the

chance of short-circuiting any of the electronic equipment.

Listen to the system and take note of the level of the Bass

Response. Connect the next Bazooka

®

 and compare the level

of the combined output to that of the single unit. If the Bass

Response increases, the Phasing is correct and you can repeat

this process on the next Bazooka. If the level of the Bass

Response drops, the Phasing is incorrect and you should reverse

the speaker connections to this Bazooka

®

 and compare again.

In short to 

INCREASE IS GOOD

, to 

DECREASE IS BAD

! Using

this method, any number of Bazooka

®

 subwoofers can be kept

in absolute phase.

PRACTICE SAFE LISTENING

Continuous exposure to high volumes of sound may cause

permanent hearing loss. High-powered auto sound systems

are capable of producing sounds well over 130 dB. Even short

periods of play at high volume levels can impair your ability

to hear necessary traffic sounds and may constitute a hazard.

Please use common sense and practice SAFE LISTENING!
