Assistant Menu
The purpose of the
Setup Assistant is to help you
set up your surround system correctly. If you follow the
steps described below, the
DD 820 M
will automatically
calibrate your loudspeakers with the help of the
measurement microphone supplied, and under normal
listening room conditions this procedure will deliver
optimum results from your system.
If the automatic calibration system is to work properly the
following conditions must be satisfied: the measurement
microphone must be set up with free space all round it,
close to your preferred listening position (e. g. on the
living room table, or on the arm of an armchair). There
must be straight-line visual contact between the
microphone and each loudspeaker.
The unit is supplied with a calibration microphone.
Connect this to the socket marked CAL MIC. on the back
panel of the
DD 820 M
. Set the system to a normal
listening volume.
Call up the Setup Assistant and the menu shown below
appears.
Main speaker:
Center speaker:
Rear speaker:
Subwoofer:
The first step is to enter the size of your loudspeakers in
the right-hand column of the menu (see
'
Loudspeaker
Menu
'
), and state whether your system includes a
subwoofer or not.
Auto-setup:
Now move to the
'
Auto-setup
'
menu point and press the
button to activate the menu point.
To ensure that the calibration process can be carried out
correctly it is essential to set the volume to the optimum
level beforehand. To help set the correct level the
DD 820 M
generates a hissing signal on the front left
channel. In the 'Volume' line on the screen you will see
the currently set volume, following by a flashing indicator
informing you which button to press.
'VOL+
' means that
the volume is too low.
'VOL-
' means that it is too high.
The calibration process is initiated by pressing the
button, but this will not work until you see '
OK
' on
the screen.
The
DD 820 M
will now carry out the automatic
calibration process. During this period you will hear
various test signals from your loudspeakers. The results
could be falsified if any loud noises occur during the
duration of the calibration process, so take care to keep
the room quiet.
The on-screen
'
Auto-setup
'
display on your TV set
keeps you constantly informed about the settings it has
established. In the
Level
column you will see the set
corrections (volume compensation), while the
Dist.
column lists the measured loudspeaker distances.

Notes:
If the calibration process was spoiled by extraneous
sounds, or if implausible results are generated for
whatever reason, you can re-start the calibration process
at any time.
The distances established by the Assistant are
calculated on the basis of acoustic reflection times. They
may vary slightly from the true geometric distances due
to signal delays in your loudspeakers.
If the automatic calibration process supplies invalid
results due to difficult acoustic conditions in your
listening room, we recommend that you should first try
varying the microphone position and / or the volume
setting in an attempt to obtain a valid result.
If this does not bring about an improvement, making
automatic calibration impossible, you can still carry out
the loudspeaker set-up procedure manually via the
'
Loudspeaker Menu
'
.
