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 84.)

! 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 LPF on 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.

— When delays occur for low sounds due

to the influence of the LPF on active

subwoofers or external amps.

! Auto TA and EQ changes the audio settings

as below:

— The fader/balance settings return to the

center position. (Refer to page 82.)

— The graphic equalizer curve switches to

Flat. (Refer to page 86.)

— When a subwoofer is connected to this

unit, it will be adjusted automatically to

both subwoofer output and high pass fil-

ter setting for rear speaker.

! If you carry out auto TA and EQ when a pre-

vious setting of this already exists, the set-

ting will be replaced.
