! 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.

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.
