GTb 1200 Mk II
Leave ample clearance between the cables and other harnesses. Use
the enclosed cable ducts at sharp-edged holes.
Note:
We recommend that you operate the GTb 1200 Mk II in conjunction
with our GTA series amplifi ers.
The GTb 1200 Mk II can be operated in normal as well as in bridged
mode (for further details, please refer to the operating 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 Mk II. 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 confi gure
the amplifi er 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 up-
per 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 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 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. 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.
