INTRODUCTION
Proper system planning is vital in order to maximize
the device’s performance and road safety. Plan
your installation carefully to avoid compromising
performance reliability of the system. Consult an
authorized Blaupunkt dealer for installation or reparation. Read the manual carefully before operating
the device for the rst time.
Safety Notes
Ensure to follow below safety notes during installation and wiring connection : -
•
Disconnect the negative terminal of the battery.
Refer to the safety notes of vehicle manufacturer.
•
Ensure positions of the holes are nowhere near
the vehicle component to avoid any damage
during drilling.
•
Incorrect installation may result in malfunction of the device or the car sound system.
Installation and Connection Instructions
•
Select a dry and well-ventilated location to
install the device.
•
The device must not be installed on the rear
shelf, rear seats or exposed locations.
•
The installation location must be suitable for
screw holes and have stable ground support.
Intergrated Fuse
•
The integrated fuse in the device protects
the output voltage and the entire electrical
system in case of malfunction. Do not replace
damaged fuse with higher current.
Switching On/O
•
This device will automatically turn on if audio
signal is detected. The device will also automatically turn o if audio signal is received.
Remote Control
1
Set the GAIN to 200mV (Min), PHASE to NORM.,
LOW PASS FILTER to Center before turning on
the device.
2
Set the Bass/Treble of head unit to zero. Set
volume to lower level.
3
Gradually increase GAIN until the desired sound
eect is achieved or until the sound distribution
in the vehicle is even.
4
Avoid setting volume of the head unit and GAIN
too high to prevent sound distortion. Ensure
speakers are functioning well to avoid sound
distortion too. Then adjust the LOW PASS FILTER
(L.P.F.) to the desired frequency.
5
Changing the LPF will change the sound output
of the subwoofer. Continue to adjust GAIN, LPF
and volume until the desiredsetting is found.
6
Play the music from the head unit while sitting
at the driver and switch between NORM and REV
to select the desired sound output setting. The
ideal PHASE is subjective and varies from one
vehicle to another, depending on the location of
the device and the acoustic characteristics of the
vehicle interior.

Solution
Examine if the ground connection is intact.
Examine if remote input has at least 5V DC.
Examine if battery power is connected correctly to the + terminal.
Ensure supplied voltage is minimum 12V.
Examine if fuse is broken and replace if necessary.
Restart the device if protection LED light is on.
Examine fuses and replace if necessary.
Examine ground connection is intact.
Examine if remote input has at least 5V DC.
Examine if RCA audio cables are connected to the right inputs.
Examine if speaker wiring is intact.
Reset Level Control
Examine the Crossover Control setting.
Observe if the device is still producing noise after turning on and o the
amplier. If yes, examine if the cables are correctly connected and if the
cables and radio are in good condition. Repair or replace if the cables or the
radio are not in good condition.
Ensure RCA connections are properly connected.
Ensure input level of the device matches the signal level of the head unit.
Always set the input level to the lowest.
Examine if crossover frequency is set correctly.
Examine if speaker wire had short-circuit.
Examine the minimum speaker impedance for the amp models is correct.
Ensure good air ventilation around the device. Add external cooling fan if
necessary.
Usually caused by poor RCA cable quality, which release noise. Use only the
best quality cables, and route them away from power cables.
Examine if RCA cable are nowhere near or attached to the vehicle chassis.
Examine if head unit is properly connected to the wires.
