sing automatic sound levelizer
While driving, the noise in the car changes
according to the driving speed and the road
conditions. The automatic sound levelizer (ASL)
monitors such varying noise and automatically
increases the volume level, if the noise
becomes greater. The sensitivity (variation of
volume level to noise level) of ASL can be set
to one of five levels.
1. Press AUDIO and then press NEXT to dis-
play "ASL".
Press NEXT until "ASL" appears.
2. Press ASL to select the automatic sound
levelizer mode.
3. Press ASL to set the automatic sound
levelizer sensitivity.
Press ASL repeatedly to switch between the
following settings:
OFF (off) = Low (low) = Mid-Low (mid-low)
= Mid (mid) = Mid-High (mid-high)
= High (high)
• When the ASL mode is exited except for
"OFF" is selected, "ASL" appears on the
basic display.
A
djusting source levels
SLA (source level adjustment) lets you adjust
the volume level of each source to prevent radi-
cal changes in volume when switching between
sources.
• Settings are based on the FM tuner volume
level, which remains unchanged.
1. Compare the FM tuner volume level with
the level of the source you want to adjust
(e.g., built-in CD player).
2. Press AUDIO and then press NEXT to dis-
play "SLA".
Press NEXT until "SLA" appears.
3. Press SLA to select the SLA mode.

4. Press 5 5 or ∞ ∞ to adjust the source vol-
ume.
Each press of 5 or ∞ increases or decreas-
es the source volume.
• "+4" – "–4" is displayed as the source vol-
ume is increased or decreased.
Note:
• Since the FM tuner volume is the control, it is not
possible to apply source level adjustments to the
FM tuner.
• The MW/LW tuner volume level can also be adjust-
ed using source level adjustment.
• The built-in CD and the multi-CD players are both
set to the same source level adjustment volume
automatically.
S
witching the digital attenuator
When listening to a CD or other source on
which the recording level is high, setting the
equalizer curve level to high may result in dis-
tortion.
You can switch the digital attenuator to low to
reduce distortion.
• Sound quality is better at the high setting, so
this is the setting usually used.
1. Press AUDIO and then press NEXT to dis-
play "D.ATT".
Press NEXT until "D.ATT" appears.
2. Press D.ATT to select the digital attenua-
tor mode.
3. Press the corresponding button to select
the digital attenuator level.
