• When the microphone is
connected, the sound in the car is
input through the microphone
and displayed on the spectrum
analyzer. This display can be
used as reference when making
the adjustment. For details of the
spectrum analyzer display, see
"Switching the display mode"
(page 53).
• This adjustment is easier when
test signals such as pink noise are
used. For information on test
signals, consult your store of
purchase.
• Even more subtle adjustments
can be used using a computer.
For details, consult your store of

• Check the playable frequency
ranges of the connected speakers
before making the equalizer
adjustments. If the speaker's
playable frequency range is 55
Hz to 30 kHz, for example,
adjusting the 40 Hz or 20 Hz
band has no effect. Additionally,
you may overload and damage
the speakers.
