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.
