DSA
Digital Signal Adaptation
With DSA, you can recall and tune in equa-
lizer functions and activate the dynamic dri-
ving noise covering function.
Overview of Equalizer functions
The HiFi reproduction in a car is affected,
for example, by the interior fittings (uphols-
tery, windows), loudspeaker positioning, etc.
With the integrated equalizer, you can tune
in nine frequency bands per channel: 60 Hz,
125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz,
4 kHz, 8 kHz, 16 kHz.
You can store and recall different settings
in five memory banks each (preset buttons
1 to 5):
With preset button 6, the corresponding
equalizer is deactivated.
For optimal acoustic control, the following
alternatives are available:
Self-calibrating equalizer
(HiFi calibration)
The set is equipped with a self-calibrating,
adaptive 9-band equalizer for four channels.
Four channels can be electronically calibra-
ted per memory bank (front left, front right,
rear left, rear right).
Manual equalizer
Separate equalizer adjustments can be per-
formed manually for front and rear per me-
mory bank.
Preset equalizer
(Default allocation of equalizer)
Permanent equalizer settings can be recal-
led with buttons 1 to 6 or with / / << >>.

HiFi calibration
You can perform and store electronic cali-
bration for five different situations.
These calibrations are stored and recalled
with the buttons 1 to 5.
You can select the following situations, for
example:
1
For the driver only
2
For driver and front passenger
3
Front passenger
4
Passengers front and rear
5
Rear passengers only.
You deactivate the equalizer with button 6
(“P-EQ OFF” in the display.)
To calibrate, you have to fix the microphone
lead (microphone opening pointing down) to
the roof lining with adhesive tape.
The position of the microphone for situation
1 (driver alone) is directly on a level with the
driver’s head. For situation 2, the micropho-
ne is between the driver and the front pas-
senger, for situation 3 on a level with the
front passenger’s head, etc.
Start HiFi calibration
During the calibration process it is impor-
tant that the surroundings are really quiet.
Any outside noises will distort the readings.
The loudspeaker radiation should not be
impaired by any objects.
The system must be switched on.
•
Position the microphone for the situati-
on to be programmed.
Incorrect calibrations result when the micro-
phone is wrongly positioned.
Depending on the vehicle and on the install-
tion position of the speakers, calibration may
be linear or with a bass boost. Try out which
setting you like more.
You can preselect with DNC. The following
stand for:
DNC-OFF
- linear frequency response
DNC-LOW - slight bass boost
DNC-MID
- medium bass boost
DNC-HIGH - stronger bass boost.
