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 twice.
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 AM tuner volume level can also be adjusted
using source level adjustment.
• The built-in CD (MP3) and the multi-CD players are
both set to the same source level adjustment vol-
ume automatically.
U
sing the auto-equalizer
The auto-equalizer is the equalizer curve creat-
ed by auto-equalizing. (Refer to "Creating the
auto-equalizer curve" on this page.)
You can turn the auto-equalizer on or off.
1. Press AUDIO and then press NEXT twice.
2. Press A.EQ to select the auto-equalizer
on/off mode.

3. Press A.EQ to turn the auto-equalizer on.
"AUTO EQ ON" appears in the display.
• Press A.EQ again to turn auto-equalizer
off.
Note:
• "A.EQ" is not displayed if auto-equalizing has not
been carried out. In this case, this mode is inactive.
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 twice.
2. Press D.ATT to select the digital attenua-
tor mode.
3. Press the corresponding button to select
the digital attenuator level.

reating the auto-equalizer curve
The auto-equalizer automatically measures car
interior acoustic characteristics, and then cre-
ates the auto-equalizer curve based on that
information.
WARNING:
• To prevent accidents, never carry out auto-
equalizing while driving. When this function
measures the car interior acoustic characteris-
tics to create an auto-equalizer curve, a loud
measurement tone (noise) may be output
from the speakers.
