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 amplifi er can only be as good as
its installation. A correct installation increases the overall
performance of your car sound system. The GTA amplifi 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 suffi 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 confi 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 2 .
– 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 off ers suffi cient air circulation for cooling the amplifi 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 fi rm support.
The amplifi er power cable must be fi 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 amplifi er and battery.
The fuse of the amplifi er protects only the amplifi 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 preamplifi 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/off
A special feature of the GTA 11250 DSP is its automatic
switch-on.
The amplifi 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 off .
Integrated fuses (3 x 30 A)
The fuses integrated in the amplifi er protect the power
amplifi 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 amplifi er with switchable +12 V
voltage source.
This allows the amplifi er to be switched on and off using the
on/off -switch of the car sound system.
Subwoofer connection
As with every audio component, the correct polarization
of amplifi er and loudspeakers is of essentially importance
for a good bass response. For this reason, ensure that the
positive connection (+) of the amplifi 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 amplifi er channel with the right
loudspeaker. Positive (+) and negative (–) connections are
wired parallel internally.
