power to car phones or mobile phones in the vehicle, or
remove them in advance. Surrounding sounds may prevent
correct measurement of the vehicle’s acoustics.
 Be sure to use the microphone for acoustical measurement.
Using another microphone may prevent measurement, or
result in incorrect measurement of the vehicle’s acoustics.
 To perform Auto EQ, the front speakers must be connected.
 When this product is connected to a power amp with input
level control, Auto EQ may be impossible if the power amp’s
input level is set below the standard level.
 When this product is connected to a power amp with an LPF
(low pass filter), turn the LPF off before performing Auto EQ.
Also, set the cut-off frequency for the built-in LPF of an active
subwoofer to the highest frequency.
 The distance has been calculated by a computer to provide
optimum delay to ensure accurate results. Do not change
this value.
— The reflected sound within the vehicle is strong and delays
occur.
— The LPF on active subwoofers or external amps delay the
lower sounds.
 If an error occurs during measurement, check the following
before measuring the vehicle’s acoustics.
— Front speakers (left/right)
— Rear speakers (left/right)
— Noise
— Microphone for acoustical measurement
— Low battery
Performing Auto EQ
CAUTION
Do not turn off the engine while the measurement is in
progress.
p
Auto EQ changes the audio settings as follows:
— The fader/balance settings return to the centre position.
 Refer to Using fader/balance adjustment on page 57
— “ Mute Level ” is set to “ Off ”.
 Refer to Switching sound muting/attenuation on page 57
p
Previous settings for Auto EQ will be overwritten.
1 Stop the vehicle in a quiet place, close all the
doors, windows and sun roof, and then turn the
engine off.
If the engine is left running, engine noise may prevent correct
Auto EQ.
p
If driving restrictions are detected during measurement,
measurement is cancelled.

Auto EQ measurement will be applied by touching [ Apply
Auto EQ ] (the results are also applied to some settings
simultaneously).
Adjusting the time alignment
By adjusting the distance from each speaker to the listening
position, time alignment is able to correct the time required for
sound to reach the listening position.
1 Measure the distance between the head of the
listener and each speaker unit.
2 Display the “ Audio ” setting screen.
 Refer to Displaying the “ Audio ” setting screen on page 57

the selected speaker and the listening position.
The following items are available:
Front Left , Front Right , Rear Left , Rear Right , Subwoofer
p
You can input the value between 0 cm and 500 cm.
p
The distance can be adjusted manually only when the listen-
ing position setting is set to “ Front-L ” or “ Front-R ”.
p
If the Auto EQ measurement has been done, the result of the

any time. The equalizer curves you can recall are as follows:
S.Bass
,
Powerful
,
Todoroki
,
Vocal
,
Flat
,
Custom1

Customising the equaliser curves
p
If the preset equalizer curve other than “ Custom1 ” or
“ Custom2 ” is modified, the equalizer curve settings in
“ Custom1 ” will be overwritten.
p
If the equalizer curve stored in “ Custom1 ” or “ Custom2 ” is
modified, each stored curve will be overwritten.
1 Display the “ Audio ” setting screen.
 Refer to Displaying the “ Audio ” setting screen on page 57
2 Touch [ Graphic EQ ].
3 Select a curve that you want to use as the basis
of customising.
4 Touch the frequency for which you want to
adjust the level.
p
If you touch “ Custom1 ” or “ Custom2 ”, recall the equalizer
curve currently stored in “ Custom1 ” or “ Custom2 ”.
p
If you trail a finger across the bars of multiple equaliser
bands, the equaliser curve settings will be set to the value of
the touched point on each bar.
Setting the auto-adjusted equaliser
You can set the auto-adjusted equalizer to suit the vehicle’s
acoustics. To use this function, the Auto EQ measurement must
be done in advance.
 Refer to Adjusting the equaliser curve automatically (Auto EQ)

Adjusting the equaliser curve
automatically (Auto EQ)
By measuring the vehicle’s acoustics, the equaliser curve can be

WARNING
A loud tone (noise) may be emitted from the speakers when
measuring the vehicle’s acoustics. Never perform Auto EQ
measurement while driving.
CAUTION
 Thoroughly check the conditions before performing Auto
EQ, as the speakers may be damaged if this is performed
under the following conditions:
— When the speakers are incorrectly connected. (For exam-
ple, when a rear speaker is connected as a subwoofer
output.)
—
When a speaker is connected to a power amp delivering
output higher than the speaker’s maximum input power
capability.
 If a microphone for acoustical measurement is not
placed in an appropriate location, the measurement tone
may become loud and measurement may take a long
time, resulting in battery drainage. Be sure to place the
microphone in the specified location.
Before operating the Auto EQ
function

Perform Auto EQ in as quiet a place as possible, with the
vehicle engine and air conditioning switched off. Also, cut
