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 Bazooka1s 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 1800 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 1800 for no good reason, or a signal processor could have a setting for phase that has been set incorrectly or the
