Equalizer Setting
The sound in a vehicle is determined to a
greater extent by the acoustic characteris-
tics of the interior than by the characteris-
tics of the loudspeaker.
Position, installation and the rear volume of,
for example, the door or the rear shelf play
a larger role.
Even if the loudspeakers are carefully se-
lected and installed resonances in the inte-
rior of the car can negatively impact the
sound.
This could lead to an elimination of the base
level or to roaring or a dominating [?] mid-
dle level.
The musical instrument or voices could be
seriously distorted or the sound could ap-
pear completely muffled.
The sound effect from a car radio could be
significantly improved if certain frequency
areas could be suppressed or amplified.
This unit is equipped with one (Nevada RDM
168) or two (Alaska RDM 168) parametric
filters.
The first filter referred to as LOW EQ can
be set to a range between 32 Hz and 500
Hz. The second filter referred to as HIGH
EQ can be set to a range between 630 Hz
and 10,000 Hz. In this case, parametric
means that the frequency and the volume
increase/decrease (+10 to -20db) can be
adjusted separately for each filter.
This parametric filter can be adjusted pre-
cisely without any measuring instruments.
The individual steps necessary for the set-
tings are described in the table.
Setting instructions
The following instructions are only recom-
mendations. You are free to implement your
own sound preferences.
When you adjust the filters we recommend
that you use a CD with music you are famil-
iar with.
The CD titles should present various instru-
ments and songs. Music that is purely elec-
tronic will not serve the purpose because
the original sound will not be known.
Set the bass, treble, balance and fader to
“0” before you set the equalizers and, if nec-
essary, turn off the loudness function.
This setting is described under “AUD” in the
quick reference.
Now listen to the CD you are familiar with.
Determine whether the sound effect meets
your expectations.
Then read the table under “Sound effect/
problem” and find a solution under “Action”.
Adjust the bass and middle sound level with
the LOW EQ filter.
For the high and middle levels, choose HIGH
EQ (only the Alaska RDM 168).
You can set the HIGH EQ and LOW EQ fil-
ters in the DSC menu:
• Press the DSC key.
Press
/ repeatedly until HIGH EQ
or LOW EQ appears in the display.
• Press << or >> once and set the level
by pressing
/ according to the table
below.
• Change the frequency areas by press-
ing << >>.
• Press the DSC key to store the new
settings.
You can activate the equalizer in the DSC
menu under the option EQ ON and deacti-
vate it under the option EQ OFF. Thus, you
are able compare the sound with and with-
out the equalizer.
