GTt 1200
The GTt 1200 can be operated in normal as
well as in bridged mode (for further details,
please refer to the operating instructions that
came with the amplifier). In any case, please
observe the RMS output power of your am-
plifier. It must not exceed the RMS power of
the GTt 1200. Non-compliance with this can
cause damage to the product in the long
term.
Setting up the subwoofer tube
In order to achieve a balanced sound, we
recommend that you configure the amplifier
as follows.
1. First set the volume control to minimum
and the crossover 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 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
finished 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
4
minimum and then resume making
your adjustments 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. Fur-
thermore, 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.
