Auto TA an d 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 autoTA and
EQ while driving.When this function measures
the car interioracoustic characteristics to create
an auto-equalizer curve, a loudmeasurement
tone (noise) maybe outputted from thespeakers.
CAUTION
! Carrying out auto TA and EQ under thefollow-
ing conditions maydamage the speakers. Be
sure to checkthe conditions thoroughly be-
fore carrying out auto TA and EQ.
— When speakersare incorrectly connected.
(e.g., When arear speaker is connectedto
a subwoofer output.)
— When aspeaker is connected toa power
amp delivering outputhigher than the
speaker’s maximum inputpower capabil-
ity.
! If the microphoneis placed in an unsuitable
position the measurement tonemay become
loud and measurement maytake a long time,
resulting in adrain on battery power. Be sure
to place themicrophone 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 75.)
! When this unit is connected to a power
amp with input level control, auto TA and
EQ may not be possible if you lower power
amp input level. Set the power amp’s input
level to the standard position.
! When this unit is connected to a power
amp with an LPF, turn off the LPFon the
power amp before carrying out auto TA and
EQ. In addition, the cut-off frequency for
built-in LPF of an active subwoofer should
be set to the highest frequency.
! The time alignment value calculated by
auto TA and EQ may differ from the actual
distance in the following circumstances.
However, the distance has been calculated
by computer to be the optimum delay to
give accurate results for the circum-
stances, so please continue to use this
value.
— When the reflected sound within a vehi-
cle is strong and delays occur.
