!
When connecting tweeters, please confirm
the tweeter
’
s usable frequency range.
When you set the cut-off frequency, set
higher than the lowest usable frequency of
the tweeter.
!
Auto TA uses higher range than 10 kHz for
measurement. Therefore, using the tweeter
that cannot reproduce 10 kHz frequency
range may damage the tweeter. When Auto
TA&EQ is operated, be sure to set the ap-
propriate cut-off frequency. Also, use the
tweeter that can reproduce 10 kHz at the
lowest usable frequency.
Carrying out auto TA and EQ
1
Stop the car in a place that is as quiet
as possible, close all doors, windows and
the sun roof, and then turn the engine off.

Fix the supplied microphone in the cen-
ter of the headrest of the driver

the microphone on the front passenger seat to
carry out auto TA and EQ.
