Operating and Installation Instructions

INTRODUCTION

Proper system planning is vital in order to maximize the device’s performance and road safety. Plan your installation carefully to avoid compromising the performance liability of the system. Consult an authorized Blaupunkt dealer for installation or reparation. 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 to ensure positions of the holes are nowhere near the
vehicle component to avoid any damage during drilling.
Incorrect installation may result in the 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.
Integrated Fuse
The integrated fuse in the device protects the output voltage and the entire electrical system in case of malfunction. Do not replace the damaged fuse with a higher current.
Switching On/Off •
This device will automatically turn on if the audio signal is detected. The device will also automatically turn off if the audio signal is received.

Set the GAIN to 200mV (Min), PHASE to NORM., LOW PASS FILTER to Center before turning on the device. Set the Bass/Treble of the 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 the 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 desired setting 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.

Recycling and Disposal
Do not dispose of your old unit in the household trash!
Use the return and collection systems available to dispose of the old device.
This manual may be updated from time to time without any notice.

TROUBLESHOOTING

If any of the following problems occur, please resort to Troubleshooting for possible solutions. Consult Blaupunkt authorized dealer if the problem persists.

Problems	Solutions
Amplifier power up failure	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 the fuse is broken and replace if necessary.
Restart the device if the protection LED light is on.
No sound output| 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.
Low sound output| Reset Level Control
Examine the Crossover Control setting.
Buzzing noise| 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| Ensure the 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 the speaker wire had short-circuited.
Amplifier temperature increased| Examining the minimum speaker impedance for the amp models is correct.
Ensure good air ventilation around the device. Add an external cooling fan if necessary.
Engine noise (static sound) interference| Usually caused by poor RCA cable quality, which releases noise. Use only the best quality cables, and route them away from power cables.
Engine noise (alternator whine) interference| Examine if RCA cables is nowhere near or attached to the vehicle chassis.
Examine if the head unit is properly connected to the wires.
