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
speakers maximum input power capabil-
ity.
! Ifthe 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 operatingthe 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 ofthe 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 ofthe 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 50.)
! When this unit is connected to a power
amp with input level control, auto TA and
EQ may not be possible ifyou lower power
amp input level. Set the power amps input
level to the standard position.
! When this unit is connected to a power
amp with an LPF, turn off the LPF on the
power amp before carrying out auto TA and
EQ. In addition, the cut-off frequency for
built-in LPF ofan active subwoofer should
be set to the highest frequency.
