Operating this unit
3
Turn LEVER to adjust the source vo-
lume.
+4 to –4 is displayed as the source volume is
increased or decreased.
Notes
! The AM volume level can also be adjusted
with this function.
! The USB/SD volume level can also be ad-
justed with this function.
Using automatic sound levelizer
During driving, noise in the car changes ac-
cording to the driving speed and road condi-
tions. The automatic sound levelizer (ASL)
monitors such varying noise and automati-
cally increases the volume level, if this noise
becomes greater. The sensitivity (variation of
volume level to noise level) of ASL can be set
to one of five levels.
1
Use M.C. to select ASL.
Refer to Introduction of audio adjustments on
page 20.
2
Press M.C. to turn ASL on.
# To turn ASL off, press M.C. again.
3
Turn LEVER to select the desired ASL
level.
Low (low)—Mid-L (mid-low)—Mid (mid)—
Mid-H (mid-high)—High (high)
Auto TA and EQ (auto-time
alignment and auto-equalizing)
Auto-time alignment automatically adjusts the
time alignment according to the distance be-
tween the listening position and each speaker.
The auto-equalizer automatically measures
the car's interior acoustic characteristics, and
then creates an auto-equalizer curve based on
that information.
WARNING
As a loud tone (noise) may be emitted from the
speakers when measuring the car's interior
acoustic characteristics, never perform auto TA
or auto EQ while driving.
CAUTION
! Thoroughly check the conditions before per-
forming auto TA and EQ as the speakers may
be damaged if these functions are performed
when:
— The speakers are incorrectly connected.
(For example, when a rear speaker is con-
nected as a subwoofer output.)
— A speaker is connected to a power amp de-
livering output higher than the speaker's
maximum input power capability.
! If the microphone is placed in an unsuitable
position the measurement tone may become
loud and measurement may take a long time,
resulting in battery drainage. Be sure to place
the microphone in the specified location.
Before operating the auto TA and EQ
function
! Perform auto TA and EQ in a quiet place,
with both the car engine and air condition-
ing switched off. Also turn off any car
phones or portable telephones in the car, or
remove them from the car. Sounds other
than the measurement tone (such as sur-
rounding sounds, engine sound, tele-
phones ringing) may prevent correct
measurement of the car's interior acoustic
characteristics.
! Be sure to perform auto TA and EQ using
the supplied microphone. Using another
microphone may prevent measurement, or
result in incorrect measurement of the
car's interior acoustic characteristics.
! In order to perform auto TA and EQ, the
front speaker must be connected.
! When muting the front speaker units, auto
TA and EQ cannot be carried out. (Refer to
page 26.)
! When this unit is connected to a power
amp with input level control, auto TA and
EQ may not be possible if the power amp's
input level is set below the standard level.
