Set Up Section
To correctly set the gain control of the ampli
fi
er to match that of the source (headunit)
use the following setup routine:
• Turn the gain control to minimum on the ampli
fi
er.
• Ensure the bass boost is set to 0 dB.
• On the headunit set all crossovers to
fl
at and both bass and treble to zero.
• Turn up the source (headunit) to approx 3/4 volume.
• Very slowly turn up the gain on the ampli
fi
er until distortion can be heard in any of the speakers
or until the volume reaches an uncomfortable listening level when this is reached turn down the
gain control slightly.
• The gain control is now set.
The setting of the crossover will directly effect the sound you will hear from the subwoofer. At its
lowest setting (50 Hz) the subwoofer will only react to frequencies from around 35 Hz to 50 Hz. At its
highest setting (250 Hz) the subwoofer will react to a larger range of frequencies from around 35 Hz to
250 Hz. Experiment with this setting to achieve a sound you are happy with that feels comfortable with
the music that you listen to.
