Auto TAand EQ (auto-timealignment and auto-equalizing)
Theauto-time alignment is automatically ad-
justedfor the distance between each speaker
andthe listening position.
Theauto-equalizer automatically measures
thecar interior acoustic characteristics, and
thencreates the auto-equalizer cur ve based
onthat information.

WARNING

Toprevent accidents, never carry out auto TA and
EQwhile driving. When this function measures
thecar interior acoustic characteristics to create
anauto-equalizer curve, a loud measurement
tone(noise) may be outputted from the speakers.
CAUTION
!Carryingout auto TA and EQ under the follow-
ingconditions may damage the speakers. Be
sureto check the conditions thoroughly be-
forecarrying out auto TA and EQ.
—Whenspeakers are incorrectly connected.
(e.g.,When a rear speaker is connected to
asubwoofer output.)
—Whena speaker is connected to a power
ampdelivering output higher than the
speaker’smaximum input power capabil-
ity.
!Ifthe microphone is placed in an unsuitable
positionthe measurement tone may become
loudand measurement may take a long time,
resultingin a drain on battery power. Be sure
toplace the microphone in the specified loca-
tion.

Beforeoperating the auto TA

and EQ function

!Carryout auto TA and EQ in as quiet a
placeas possible, with the car engine and
airconditioning switched off. Also cut
powerto car phones or portable telephones
inthe car, or remove them from the car be-
forecarrying out autoTA and EQ. Sounds
otherthan the measurement tone (sur-
roundingsounds, engine sound, tele-
phonesringing etc.) may prevent correct
measurementof the car interior acoustic
characteristics.
!Besure to carry outauto TA and EQ using
thesupplied microphone. Using another
microphonemay prevent measurement, or
resultin incorrect measurement of the car
interioracoustic characteristics.
!Whenfront speaker is not connected, auto
TAand EQ cannot be carried out.
!Whenmuting the front speaker units, auto
TAand EQ cannot be carried out. (Refer to
