Adjust gain and crossover.
Setting Gain
Turn gain knob on Thunderform pre-amp to minimum, counter clock-
wise. Play a favorite tape or compact disc that contains consistent music
and bass. Turn the source unit to maximum listening level. You should
know that some source units will produce distortion or “clip” before the
unit reaches maximum volume. Reduce volume to the loudest listening
level before distortion. Turn the gain knob on the Thunderform pre-amp
clockwise until the speaker starts to distort and reduce gain to loudest
listening level before distortion.
Optional
- The EBC, or Electronic Bass Control, allows a remote bass
control to be adjusted from the driver's seat.
Setting Crossover
You should set the crossover to your own personal listening taste. The
crossover is adjustable to any frequency between 50Hz (counterclock-
wise) to 150Hz (clockwise). As a guideline, the goal is to create the illu-
sion of bass up front. The higher the crossover point the more “audibly
visible” your sub is going to be. Take your time and really listen to your
system, grab a soda and a few of your favorite tunes and have fun.
