PRODUCT INFORMATION
CAUTIONS
Proper system planning is vital in order to maximize the device’s performance
and road safety. Plan your installation carefully to avoid comprom1s1ng
performance reliability of the system. Consult an authorized Blaupunkt dealer
for installation or preparation. Read the manual carefully before operating
the device for the first 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 the vehicle manufacturer.
- Ensure positions of the holes are nowhere near the vehicle component to avoid any damage during drilling.
- Ensure cross section of the cable is no less than 2.Smm2 if the positive and negative cables are too long.
- 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 in overly exposed location such on the rear shelf, rear seat etc.
- The installation location must be suitable for screw holes and have stable ground support.
lntergrated 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/Off
This device will automatically turn on if audio signal is detected. The
device will also automatically turn off if audio signal is received.

This product is not intended for sale in the United States and Canada. If
purchased in the U.S. or Canada, this product is purchased on as-is basis. No
warranty, whether expressed or implied is provided in the U.S. or Canada.
Remote Control
- Set the GAIN to 200mV (Min), PHASE to NORM., LOW PASS FILTER to Center before turning on the device.
- Set the Bass/Treble of head unit to zero. Set volume to lower level.
- Gradually increase GAIN until the desired sound effect is achieved or until the sound distribution in the vehicle is even.
- 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.
- Changing the LPF will change the sound output of the subwoofer. Continue to adjust GAIN, LPF and volume until the desiredsetting is found.
- 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.
Disposal Notes
- Do not dispose of your old unit in the household trash!
- Use the return and collection systems available to dispose of the old device.

TROUBLESHOOTING
Problem
Amplifier power
| Solution
Examine if the ground connection is intact.
---|---
up failure| Examine if remote input has at least SV 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.
Protection LED lights on when turn on| Examine if speaker wire had short-
circuit.
Turn volume down from head unit to prevent overdriving the device.
Device might need service or repair, if protection LED light is still on after
resetting the device.
No sound output
Low sound output Buzzing noise
| Examine fuses and replace if necessary.
Examine if ground connection is intact.
Examine if remote input has at least SV 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 off the amplifier. 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.
Squealing noise
interference
| Ensure RCA connections are properly connected.
Distorted sound output
Amplifier temperature increased
| 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 if the minimum speaker impedance for the amp models is correct.
Ensure good air ventilation around the device. Add external cooling fan if
necessary.
Engine noise (static sound) interference
Engine noise (alternator
whine) interference
| 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.
If any of the following problem occur, please resort to Troubleshooting for the possible solutions. Consult Blaupunkt authorized dealer if problem persist.
