nal switching current supply is acti-
vated and the unit is operational.
5LEFT/RIGHT FRONT CHANNEL
SIGNAL INPUTS
To be connected to the front channel
output of the source unit.
6PARALLEL INPUT SWITCH
“IN”: When the parallel input is in the
“IN” position, the input signals coming
in through the front channel signal in-
puts are split and directed to the front
and rear channels simultaneously.
(This feature is to be engaged when
the source unit has no separate front,
rear or subwoofer channel outputs.)

pendent front and rear channel out-
puts, disengage the parallel input by
sliding the switch to the “OUT” posi-
tion.

safety instructions:
-Disconnect the negative terminal of the
battery! When doing so, please observe
the vehicle manufacturer’s safety instruc-
tions.
-Make sure you do not damage vehicle
components when drilling any holes.
-The cross sections of the positive and
negative cables must not be less than
0.75 mm2.
-Depending on the model, your vehicle
may differ from the description provided
here. We accept no responsibility for any
damages due to incorrect installation or
connection or for any consequential
damages.
If the information provided here is not
suitable for your specific installation re-
quirements, please contact your
Blaupunkt dealer, your vehicle manufac-

CROSSOVER DESIGN
BASS BOOST CIRCUITRY WITH QUA-
SI-PARAMETRIC EQUALIZATION
A sealed enclosure ensures a woofer’s fre-
quencyresponse will roll offata rateof 12 dB
peroctavebelowtheenclosure’sresonantfre-
quency. The quasi-parametricequalization 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
eliminatesswitchingnoisedue to voltagefluc-
tuation.
FREQUENCY MULTIPLIER
The front high-pass section is equipped with
afrequencymultiplierswitchthatcanbeused
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
Themobileelectroniccrossoverhas 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.

Note:
c. Preset the volume of the source unit to
its minimum (otherwise, when the source
unit is turned on, the sudden surge of
high power from the amplifiers might
cause damage to the audio components)
2. Turn the source unit on and
slowly increase the source unit
volume:
a. No Sound At All
•Turn the system off immediately.
•Check if connections have been made
properly (refer to section entitled Con-
nections for details).
•Use a Volt/Ohm meter to make sure a
good chassis ground is established for
each component that needs to be
grounded.
•Check the power input of all systems
•Check if the remote on/off terminals of all
system components are properly con-
nected to a positive 12-volt source.
•If everything is in order, turn the power
on again. If the problem persists, refer to
the section entitled TROUBLE SHOOT-
ING GUIDE for assistance.
b. Obvious Distortion
Turn the system off and refer to the sec-
tionentitled TROUBLE SHOOTING
GUIDE for assistance.
c. Out-of-Phase Problem (i.e.Abnormal
Bass)
Turn the system off and refer to the sec-
tionentitled TROUBLE SHOOTING
GUIDE for assistance.
3. Noise check
Beforemountingthemobileelectroniccrosso-
ver and the other audio components perma-
nently, please carry out the following noise
check:
1. Start the engine and turn on the power of
the source unit.
2. Rev the engine whilst it is idling and vary
the audio volume to check for emitted en-
gine noise or a tick-tick noise, refer to the
TROUBLE SHOOTING GUIDE for as-
sistance. If the problem persists, consult
your local dealer directly.
3. If no unwanted noise is detected, double
check all the wiring and cables to ensure
they are secure. Then securely tighten
the mounting screws of all the audio
components.

TROUBLE SHOOTING GUIDE
FINAL SYSTEM CHECK
1. No power
2. “Flickering”: The electronic crossover
power indicator switches on and off re-
peatedly when the audio system is on.
3. The electronic crossover heats up
quickly even when the audio system is
at moderate volume.
SYMPTOM PROBALE CAUSE
TROUBLE SHOOTING GUIDE
•Check all the ground, B+ and remote
control terminals for tight connection.
•Check all fuses.
•Use a Volt/Ohm meter to check all cur-
rent carrying cables to see if the sys-
tem is receiving +12V.
•Check whether the electronic crossover
B+ power input is connected directly to
the battery.
•Check the battery voltage: if low, re-
charge or replace it.
•Check whether the electronic crossover
has a good ground connection
(i.e.whether the ground wire is making
good contact with a bare spot of the ve-
hicle chassis.).
•Check that all ground connections of
the entire system are making good
contact with bare metal.
•Check for speaker short: circuit discon-
nect speaker cable from amplifier. Test
speaker with a Volt/Ohm meter. If there
is a short circuit in the speaker wiring,

TROUBLE SHOOTING GUIDE
SYMPTOM PROBALE CAUSE
4. When the engine is running, the audio
system emits a radiating noise that re-
mains unchanged or disappears when
the volume is increased.
5. When the engine is running, the audio
system emits a radiating noise that in-
creases or decreases with the volume of
all program sources (for radio, tape or
CD).
6. When the engine is running, the audio
system emits a whining noise that in-
crease or decreases ONLY with the vol-
ume.
7. Obvious distortion at low volume.
8. Overall sound effect is good, but bass is
abnormal (more bass at the two extreme
settings of the balance control than at
the center setting).
replace the entire speaker cable or re-
insulate any exposed wire with electri-
cal tape.
•Check all the +power cables to see if
they are connected correctly.
•Check all the ground connections of
the entire system for good contact with
bare metal of the vehicle chassis.
•Check whether the source unit and the
electronic crossover are connected to
the vehicle ground at the same refer-
ence point.
•Install a 10 amp in-line filter on the red
power cable of the mobile electronic
crossover.
•If the noise persists, check the three-
phase current diodes and the voltage
regulator.
•This is commonly known as “radiated”
noise. It is NOT caused by the mobile
electronic crossover and thus is be-
yond the scope of this manual. Please
contact your local retailer/installer for
assistance.
•Output level of various channels is not
compatible, refer to section entitled
FINAL SYSTEM CHECK.
•The subwoofers are “out-to-phase” with
each other, thus canceling the bass
when the balance control is at the
center position. Check the wiring from
the amplifier to the subwoofers (posi-
tive “+” to positive “+” and negative “-” to
negative“-”)
