Installation and connecting instructions
Warning! Accident risk!
Do not mount the GTb 1200 SC on the rear
shelf, rear seat or at any position which is
open towards the front. Blaupunkt recom-
mends to install the system in the boot.
The GTb 1200 SC can be operated in normal as well as in
bridged mode (for further details, please refer to the operat-
ing instructions that came with the amplifi er). In any case,
please observe the RMS output power of your amplifi er. It
must not exceed the RMS power of the GTb 1200 SC. Non-
compliance with this can cause damage to the product in
the long term.
Note:
We recommend that you operate the GTb 1200 SC in con-
junction with our GTA series amplifi ers.
Setting up the subwoofer tube
In order to achieve a balanced sound, we recommend that
you confi gure the amplifi er as follows.
1.
First set the volume control to minimum and the cross-
over control to its middle position.
2.
Now play some music on your car sound system that
you are very familiar with and that contains some low
bass (e.g. pop music). Now slowly increase the volume
of the subwoofer until you feel that the sound of the
music is well balanced, i.e. the bass is neither too weak
nor overpowering.
3.
Now listen to the relationship between deep male voices
and the upper bass and also take note of the relationship
between the upper bass (kick bass) and the lower bass.
The bass should ideally sound crisp and have a clear low
18
bass component, and male voices should neither sound
too weak nor should they billow out. If you are happy with
the sound then you are already fi nished with the setup
process. If not, continue as described in points 4 and 5.
4.
If male voices seem to billow out or the low bass is too
weak, you should turn the crossover control slightly
towards minimum and then resume making your adjust-
ments as described in point 2 onwards.
5.
If the bass sounds low but dirty and booming or the male
voices sound too weak, you should turn the crossover
control slightly towards maximum. Furthermore, you
should set the phase control (if present) so that the upper
bass sounds as powerful as possible. Next, resume making
your adjustments as described in point 2 onwards.
