CROSSOVER DESIGN
BASS BOOST CIRCUITRY WITH
QUA-
SI-PARAMETRIC EQUALIZATION
A sealed enclosure ensures a woofer’s fre-
quency response will roll off at a rate of 12 dB
per octave below the enclosure’s resonant fre-
quency. The quasi-parametric equalization of
our BASS BOOST circuitry provides a single
octave boost of 12 dB at 45 Hz to ensure
smooth and accurate bass response.
DC/DC REGULATED SWITCHING
POWER SUPPLY
This power supply design provides constant
voltage to the crossover regardless of the
battery’s voltage to ensure consistent output
performance at all times. This design also
eliminates switching noise due to voltage fluc-
tuation.
FREQUENCY MULTIPLIER
The front high-pass section is equipped with
a frequency multiplier switch that can be used
to multiply the crossover frequency points.
With the additional selectable crossover
points, setting the system becomes a very
precise procedure.
PARALLEL INPUT SWITCH
In order that a source unit has a single pair of
signal outputs, an adapter is needed to split
the front and rear inputs. With the electronic
crossover, by engaging the parallel input fea-
ture, an external adapter is no longer neces-
sary.
FRONT/REAR INPUTS WITH
FRONT/REAR/SUBWOOFER OUTPUTS
The mobile electronic crossover has front and
rear preamp inputs and front and rear out-
puts, as well as a constant subwoofer output
that is independent of the front/rear fader po-
sition on the source unit.
ADJUSTABLE OUTPUT LEVEL
STEREO/MONO SUBWOOFER
GOLD PLATED RCA CONNECTORS
REMOTE LEVEL CONTROL (Option)
This remote device permits adjustment of the
low-pass level from the front of your vehicle.
