Parametric Equalizer Adjustments - Alpine DVA-9860 Mode D'emploi

Parametric Equalizer Adjustments

The frequency bands of the graphic equalizer are fixed. This makes it
very difficult to correct for undesired peaks and dips at specific
frequencies. The parametric equalizer's centre frequency can be tuned
to these specific frequencies. Then, the bandwidth (Q) and level are
fine-tuned, independently, to make the necessary corrections. The
parametric equalizer function is an advanced tool for serious
audiophiles.
1
Check that Defeat mode is off (page 17).
2
Press and hold CENTER f. for at least 2 seconds.
The audio processor control mode is activated.
3
Select the P-EQ mode by pressing CENTER f.
repeatedly.
4
Select L+R or L/R by pressing and holding BAND
for at least 2 seconds.
L+R: Sets the same adjustment values for the left and
right channels.
L/R: Different adjustment values can be set for the left
and right channels.
When graphic EQ is adjusted, this setting will be turned
off.
5
Select the desired channel by pressing g or
f.
When L+R is selected :
FRONT → REAR → CENTER → SUBWOOFER → FRONT
When L/R is selected :
FRONT L → FRONT R → REAR L → REAR R → CENTER
→ SUBWOOFER → FRONT L
• The speakers display differs, depending on the connected speakers.
6
Press BAND to select the band.
Adjustable bands:
FRONT/REAR/CENTER: 5 bands
SUBWOOFER:
7
Select the frequency by turning and then pressing
the Rotary encoder.
The adjustable frequency changes according the band.
8
Adjust the band width (Q) by turning and then
pressing the Rotary encoder.
The band width is adjustable in 6 steps: 0.5/1/2/3/4/5
2 bands
9
Adjust the level (LEVEL) (±9dB 1dB step) by
turning and then pressing the Rotary encoder.
10
To adjust other bands, repeat steps 6 to 9.
11
To adjust other channels, repeat steps 5 to 9.
12
When the setting is complete, press and hold
CENTER f. for at least 2 seconds.
The unit returns to the normal mode.
Press CENTER f. to select another item to be set.
• When the speaker is set to the "OFF" mode, the parametric
equalizer for that speaker cannot be set. Refer to "Setting the
Speakers" (page 30).
• It is not possible to adjust the frequencies of adjacent bands within
7 steps.
• Check the playable frequency ranges of the connected speakers
before making the equalizer adjustments. If the speaker's playable
frequency range is 55 Hz to 30 kHz, for example, adjusting the
40 Hz or 20 Hz band has no effect. Additionally, you may overload
and damage the speakers.
• When the parametric EQ is adjusted, the adjustment for graphic
EQ becomes ineffective.
• When the setting is complete, it is recommended to store the setting
contents. For storing, refer to page 37.
