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 ampli 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-o 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 ampli 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  lter to limit the low-frequency

response of the device. The setting of the subsonic  lter

suppresses all frequencies below the de 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

 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 ampli er to the output voltage of your car

sound system preampli 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 e ect.

A few important explanations in this context:

By turning the GAIN control clockwise, the input sensitivity

of the ampli 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 ampli er output, even

if it sounds like that at  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 ampli 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 con er le montage de l'ampli-

 cateur GTA à un spécialiste. Si vous souhaitez cependant

effectuer vous-même ce travail, lisez soigneusement la

présente Notice de montage et accordez-vous su samment

de temps pour le montage.
