Set Up Section
Gain Control Setting
To correctly set the gain control of the amplier to match that of the source
(headunit) use the following setup routine:
● Turn the gain control to minimum on the amplier.
● On the headunit set all crossovers to 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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.
Crossover Setting
All EDGE active enclosures come with a built in Frequency Control. This
will allow you to set the frequency at which the amplier lter will take affect.
It is variable from 50 Hz - 250 Hz. 50 Hz will produce only low frequencies,
very deep bass. Whilst 250 Hz will produce low and higher punchy bass
frequencies. In the correct set up the bass should not be overly prominent,
although some users may wish to have a bigger bass presence.
To set this correctly follow the following routine:
● Firstly set the gain control correctly as described above.
● Play a known piece of dynamic music through the entire system.
● Use the Frequency Control to blend the frequencies from the subwoofer
into the rest of the vehicle so that the bass coming from the enclosure
disappears’ or blends in with the rest of the car speakers.
The crossover is now set.
Troubleshooting
● Before removing the amplier, refer to the list below and follow the
suggested procedures.
● If in any doubt get help from a car audio installation expert or EDGE dealer.
