Warranty

We provide a manufacturer's warranty for products bought

within the European Union. For devices purchased outside

the European Union, the warranty terms issued by our re-

spective responsible domestic agency are valid. The warranty

terms can be called up from www.blaupunkt.com.

Recommendation

The performance of an ampli er can only be as good as

its installation. A correct installation increases the overall

performance of your car sound system. The GTA ampli er

should be installed by a trained person. If you would to install

it yourself, please read these installation instructions very

carefully and allow yourself su cient time for the installation.

In conclusion, allow us a few words about the topic of health

protection:

During the playback of music in your vehicle, please consider

that continuous sound-pressure levels above 100 dB can

lead to permanent damages to the human ear and even to

loss of hearing. Using today's high-performance systems

and loudspeaker con gurations allows for reaching sound-

pressure levels above 130 dB.

Safety notes

Please observe the following safety notes during the instal-

lation and connection.

– Disconnect the negative pole of the battery! Observe the

safety notes of the vehicle manufacturer.

– When you drill holes, ensure that you do not damage any

vehicle components.

– The cross section of the plus and minus cable may not

be less than 10 mm

– Use cable glands for holes with sharp edges.

– An incorrect installation can result in malfunctions of

the electronic vehicle systems or your car sound system.

Installation and connection instructions

With respect to accident safety, the GTA 11250 DSP must be

secured in a professional way.

When selecting the installation location, select a dry location

that o ers su cient air circulation for cooling the ampli er.

The GTA 11250 DSP must not be installed on rear shelves, rear

seats or other locations that are open to the front.

The installation surface must be suitable to accept the ac-

companying screws and provide a  rm support.

The ampli er power cable must be  tted with a fuse no more

than 30 cm from the battery to protect the vehicle battery in

case of a short circuit between power ampli er and battery.

The fuse of the ampli er protects only the ampli er, not the

vehicle battery.

Only loudspeakers with 2 - 4 Ω impedance may be used

(see table or installation drawings). Observe the maximum

power handling capacity (music output). Do not connect

loudspeakers to earth, use only the referenced terminals.

Audio inputs

The preampli er outputs are connected to the cinch (RCA)

sockets via a shielded audio line (see Fig. 3).

Plus / minus connection

– We recommend a minimum cross section of 10 mm

– Route commercially available plus cables to the battery

and connect via fuse holder.

– Use cable glands for holes with sharp edges.

– Securely fasten commercially available minus cables to a

noise-free earth point (chassis screw, chassis metal) (not

to the minus pole of the battery).

– Scrap the contact surfaces of the earth point until they

are bright and grease with graphite grease.

Switching on/o

A special feature of the GTA 11250 DSP is its automatic

switch-on.

The ampli er automatically switches on if a music signal

is received. If no music signal is received for more than

60seconds, the GTA 11250 DSP automatically switches o .

Integrated fuses (3 x 30 A)

The fuses integrated in the ampli er protect the power

ampli er and the entire electrical system in case of an error.

If a replacement fuse is used, never bridge fuses or replace

them with a type with higher current.

Connection examples

Connection of the voltage supply ..................................Fig. 2

Audio inputs ...........................................................................Fig. 3 - 4

Loudspeaker connections .................................................Fig. 5

Remote control connection ................................................Fig. 6

Remote connection of the ampli er with switchable +12 V

voltage source.

This allows the ampli er to be switched on and o using the

on/o -switch of the car sound system.

Subwoofer connection

As with every audio component, the correct polarization

of ampli er and loudspeakers is of essentially importance

for a good bass response. For this reason, ensure that the

positive connection (+) of the ampli er is connected with

the positive connection (+) of the loudspeaker; the same

applies to the negative connections (–). In addition, the

left amplifier channel must be connected with the left

loudspeaker and the right ampli er channel with the right

loudspeaker. Positive(+) and negative (–) connections are

wired parallel internally.
