Set Up Section
To correctly set the gain control of the amplifier to match that of the source (headunit) use the following setup routine:
Turn the gain control to minimum on the amplifier.
Ensure the bass boost is set to 0 dB.
On the headunit set all crossovers ( if applicable) to flat 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 amplifier 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 depend on what kind of speaker you are installing.
For a subwoofer it is recommended that the crossover is set to Low Pass and the frequency is set to match that of the
speakers specifications, or your preferred frequency - this is usally about 60 - 120
For a pair of full range speakers it is recommended that the crossover is set to Flat. The two frequency controls will then
have no effect on the amplifiers output and the speaker will receive a full range signal. However, using the high pass
crossovers will allow more control of your speakers. By removing the bass (low frequencies) the speakers can perform at
higher volumes with less distortion.
Note: The smaller the speaker, the less bass it can handle. Adjust the crossover to get the most and best sound from your
speakers. The easiest was to do this is by limiting the amount of bass you feed them.
For a pair of speakers with a passive crossover it is recommended that the crossover is set to High Pass and the frequency
is set to match that of the speakers specifications. - This is usually about 40 - 120Hz

By using the crossovers correctly you will not only lengthen the life of your speakers but you will also get better performance
from them. To optimise your setup seek the advise of a professional installation engineer or visit your local VIBE audio dealer.
