Using auditory user interface
AUI (auditory user interface) lets you adjust
the volume level of AUI sounds output when
operating this unit. Depending on the opera-
tions, different AUI sounds are output.
! No AUI sounds are output when the
sources are off.
! No AUI sounds are output when the level is
set to 0.
1
Use MULTI-CONTROL to select
AUI sound level.
AUI sound level appears in the display.
2
Push MULTI-CONTROL up or down to
adjust AUI sound level.
Each time MULTI-CONTROL is pushed up or
down, AUI sound level increases or decreases.
Level 0 to Level 12 is displayed as AUI sound
level is increased or decreased.
Auto TA and EQ (auto-time
alignment and auto-
equalizing)
The auto-time alignment is automatically ad-
justed for the distance between each speaker
and the listening position.
The auto-equalizer automatically measures
the car interior acoustic characteristics, and
then creates the auto-equalizer curve based
on that information.
WARNING
To prevent accidents, never carry out auto TA and
EQ while driving. When this function measures
the car interior acoustic characteristics to create
an auto-equalizer curve, a loud measurement
tone (noise) may be outputted from the speakers.

CAUTION
! Carrying out auto TA and EQ under the follow-
ing conditions may damage the speakers. Be
sure to check the conditions thoroughly be-
fore carrying out auto TA and EQ.
— When speakers are incorrectly connected.
(e.g., When a rear speaker is connected to
a subwoofer output.)
— When a speaker is connected to a power
amp delivering output higher than the
speaker's maximum input power capabil-
ity.
! If the microphone is placed in an unsuitable
position the measurement tone may become
loud and measurement may take a long time,
resulting in a drain on battery power. Be sure
to place the microphone in the specified loca-
tion.
Before operating the auto TA
and EQ function
! Carry out auto TA and EQ in as quiet a
place as possible, with the car engine and
air conditioning switched off. Also cut
power to car phones or portable telephones
in the car, or remove them from the car be-
fore carrying out auto TA and EQ. Sounds
other than the measurement tone (sur-
rounding sounds, engine sound, tele-
phones ringing etc.) may prevent correct
measurement of the car interior acoustic
characteristics.
! Be sure to carry out auto TA and EQ using
the supplied microphone. Using another
microphone may prevent measurement, or
result in incorrect measurement of the car
interior acoustic characteristics.
! When front speaker is not connected, auto
TA and EQ cannot be carried out.
! When muting the front speaker units, auto
TA and EQ cannot be carried out. (Refer to
page 51.)
