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

purchase.

• 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.
