BLAUPUNKT GTr 115 A Active Subwoofer
CAUTIONS
Proper system planning is vital to maximize the device’s performance and road
safety. Plan your installation carefully to avoid compromising the performance
and 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 below during installation and wiring
connection: –
- Disconnect the negative terminal of the battery. Refer to the safety notes of the vehicle manufacturer.
- Ensure the positions of the holes are nowhere near the vehicle component to avoid any damage during drilling.
- Ensure the 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 locations such as on the rear shelf, rear seat, etc.
- 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.

Remote Control
- Set the GAIN to 200mV (Min), PHASE to NORM., and LOW PASS FILTER to Center before turning on the device.
- Set the Bass/Treble of the head unit to zero. Set the volume to a 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.
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
If any of the following problems occur, please resort to Troubleshooting for the possible solutions. Consult Blaupunkt’s authorized dealer if the problem persists.
Problem
Amplifier power
| Solution
Examine if the ground connection is intact.
---|---
up failure| Examine if remote input has at least SV DC.
Examine if the battery power is connected correctly to the terminal.
Ensure the supplied voltage is a minimum of 12V.
Examine if the fuse is broken and replace if necessary.
Restart the device if the protection LED light is on.
Protection LED lights on when turn on| Examine if the speaker wire had short-
circuit.
Turn the volume down from the head unit to prevent overdriving the device.
The device might need service or repair, if the protection LED light is still
on after
resetting the device.
No sound output
Low sound output Buzzing noise
| Examine fuses and replace them if necessary.
Examine if the 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 the 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 the input level of the device matches the signal level of the head
unit.
Always set the input level to the lowest.
Examine if the crossover frequency is set correctly.
Examine if the 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 an external cooling fan if
necessary.
Engine noise (static sound) interference
Engine noise (alternator
whine) interference
| Usually caused by poor RCA cable quality, which releases noise. Use only the
best quality cables, and route them away from power cables.
Examine if RCA cables are nowhere near or attached to the vehicle chassis.
Examine if the head unit is properly connected to the wires.
