The current DNC setting appears in the dis-
play.
•
Use << >> to select the setting you
wish to use for the HiFi calibration.
•
Press DSA twice briefly.
•
Press -dB until “EL” appears.
•
Press the corresponding button (1 to 5)
for approx. 2 seconds (BEEP).
“MicPos 8” appears in the display, the count-
down is on. You now have 8 seconds to leave
the car. Fully automatic calibration then com-
mences.
Ensure that everything is as quiet as possible
during this process.
Once the calibration process is complete, the
display shows “EQ-READY” and switches to
the last set parameter.
Checking/modifying HiFi calibration
If necessary, you can check and correct the
automatic calibration of a channel:
•
Press DSA briefly,
•
press -dB until “EL” appears.
The four selectable channels appear in the
display with the following characters:
EL
- front left
ER
- front right
EL
- rear left
ER
- rear right
•
Select the channel with / .
•
Select any frequency band you may
wish to correct with << >>.
The set frequency is indicated by a flashing
bar.
•
You can alter the adjustment of the
frequency band with / .
When modifications have been completed,
press << >> until no more frequency bands
are flashing. If necessary, alter further elec-
tronically calibrated channels as described
above. The last setting is stored automatical-
ly.
Note:
All of the four loudspeakers should be con-
nected for the calibration.
If a loudspeaker is not recognized because it
is defective, not hooked up or masked, linear
equalizer adjustment is made for the corre-
sponding pair of loudspeakers. Accordingly,
the balance/fader setting is only partly possi-
ble.
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
The situation has to be really quiet for calibra-
tion, extraneous noises give a false reading.
There should be no-one in the car, objects
must not impair the reflection of the
loudspeakers. 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.
•
Press DSA twice briefly.
