GTA 11250 DSP
DSP sound settings
The following options are available to optimize the sound
for the use of a subwoofer:
– BASS BOOST control
The BASS BOOST control is used to adjust the bass re-
sponse of the amplifi er. The adjustment range is from
0 dB to +12 dB.
– X-OVER control
For the GTA 11250 DSP, the type of frequency crossover
("Low-Pass") can be adjusted. Select the cut-off frequency
up to which higher frequencies should be blocked. Only
frequencies that are below the cut-off frequency are
passed on to the loudspeakers.
Example:
At a setting of 80 Hz, the amplifi er has a frequency range
of 10 Hz to 80 Hz.
– SUBSONIC control
To avoid interferences from extremely low frequencies,
you can use the subsonic fi lter to limit the low-frequency
response of the device. The setting of the subsonic fi lter
suppresses all frequencies below the defi ned frequency.
Example:
At a setting of 40 Hz, the frequency range from 0 Hz to
40 Hz is being suppressed.
– PHASE control
This control allows the step less change of the phase posi-
tion of the subwoofer from 0° to 180°. It is used for the
fi ne tuning with the other connected loudspeakers and if
set correctly, it can prevent any possibly occurring mutual
cancellation of low frequencies within the audio system.
– GAIN control
The GAIN control is used to adjust the input sensitivity
of the power amplifi er to the output voltage of your car
sound system preamplifi er output. The adjustment range
is from 0.2 V to 5 V. If a car sound system of a third party
manufacturer is connected, the input sensitivity must be
adjusted corresponding to the manufacturer data.
The GAIN control can also be operated via the enclosed
cable remote control. For this purpose, the remote control
must be connected to the REMOTE socket. As long as the
remote control is connected, changes made with the GAIN
control of the GTA 11250 DSP have no eff ect.
A few important explanations in this context:
By turning the GAIN control clockwise, the input sensitivity
of the amplifi er and, therefore, also the volume increases.
However, this is not a volume control. In the end position,
it is not possible to achieve a higher amplifi er output, even
if it sounds like that at fi rst. The system merely increases
the volume faster if the volume control of the car sound
system is turned up.

Recommandation
Les performances d'un amplifi cateur ne seront jamais meil-
leures que son installation ne le permet. Une installation
correcte augmente les performances d'ensemble de votre
système audio. Vous devriez confi er le montage de l'ampli-
fi cateur GTA à un spécialiste. Si vous souhaitez cependant
effectuer vous-même ce travail, lisez soigneusement la
présente Notice de montage et accordez-vous suffi samment
de temps pour le montage.
