Auto TA and EQ (auto-time

alignment and auto-

equalizing)

Only when the multi-channel processor (e.g.,

DEQ-P7650) is connected to this unit, you can

operate this function.

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.

! 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.
