tim regulatorom basa te eventualno uključenom Loudness

Safety Notes
Please observe the following safety notes during the instal-
lation and connection.
Disconnect the negative terminal of the battery before
carrying out installation and connection work.
Observe the vehicle manufacturer's safety instructions
(regarding airbags, alarm systems, trip computers,
vehicle immobilisers).
When you drill holes, ensure that you do not damage any
vehicle components.
If the positive and negative cable are extended, ensure
that the cross section is not less than 2.5 mm
2
.
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 GTs 6902 A
must be secured in a professional way.
The GTs 6902 A may be installed only in the
spare wheel well and not on rear shelves,
rear seat benches or other locations that are
open to the front.
Use suitable threaded rods or ratchet straps
to ensure a fi rm support (see Fig. 1).
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.
Switching on/off
One of the special features of the GTs 6902 A is its
automatic
switch-on
.
The subwoofer box automatically switches on if a music
signal is received.

is connected to the positive pole of the

to negative vehicle ground.
The control of the GTs 6902 A should ideally be a two-
channel control, either via the preamplifi er outputs or the
loudspeaker outputs of the car sound system. A control
solely via the right or left channel is also possible since the
low-frequency portion of the music is generally identical
on both channels.
Audio inputs
You can select between 3 diff erent audio inputs;
Cinch (RCA)
Hi level (loudspeaker connections)
RF Link (wireless transmission)
Use only one of the audio inputs; otherwise, it may lead to
audio interferences.
The preamplifi er outputs are connected to the cinch (RCA)
sockets

of the subwoofer box via a shielded sound
cable.
With control via the loudspeaker outputs, the input connec-
tions of pos.

are fed to the closest loudspeaker cables
(front or rear) on the left and right. They are separated and
connected to the input connections. The polarity of the
+ or - connections must be observed. Bridge output stages
(BTL) can also be connected directly without an additional
adapter.
For wireless transmission of the audio signal, connect the
receiver to the RF Link socket

.
TIM function:
For car sound systems with activated TIM function, the
GTs 6902 A must be controlled via the loudspeaker outputs
of the car sound system and not via the RCA inputs (see
page 32 / Fig. 2 of the operating instructions).
