Using the equalizer
Recalling equalizer curves
There are seven stored equalizer curves that you can easily recall
at any time. Here is a list of the equalizer curves:
●
S.Bass
is a curve in which only low-pitched sound is boosted.
●
Powerful is a curve in which low- and high-pitched sounds
are boosted.
●
Natural is a curve in which low- and high-pitched sounds
are slightly boosted.
●
Vocal is a curve in which the midrange, which is the human
vocal range, is boosted.
●
Flat is a flat curve in which nothing is boosted.
●
Custom1
is an adjusted equalizer curve that you create. If
you select this curve, the effect is applied to all AV sources.
●
Custom2
is an adjusted equalizer curve that you create. If
you select this curve, the effect is applied to all AV sources.

Customizing the equalizer curves
You can adjust the currently selected equalizer curve setting
as desired. Adjustments can be made with a 13-band graphic
equalizer.

If you make adjustments when a curve “ S.Bass ”, “ Powerful ”,
“ Natural ”, “ Vocal ”, or “ Flat ” is selected, the equalizer curve
settings will be changed to “ Custom1 ” mandatorily.
p
If you make adjustments when the “ Custom2 ” curve is
selected for example, the “ Custom2 ” curve will be updated.
p
“ Custom1 ” and “ Custom2 ” curves can be created common
to all sources.

of customizing.
4 Touch the frequency for which you want to
adjust the level.

If you trail a finger across the bars of multiple equalizer
bands, the equalizer curve settings will be set to the value of
the touched point on each bar.
Using the auto-adjusted equalizer
You can set the auto-adjusted equalizer to suit the vehicle’s
acoustics. To use this function, the vehicle’s acoustics must be
measured in advance.

Adjusting the equalizer curve
automatically (Auto EQ)
By measuring the vehicle’s acoustics, the equalizer curve can be
adjusted automatically to suit the vehicle interior.
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
example, 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 (sold
separately) 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
power to car phones or cellular 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
(sold separately). 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 (sold separately)
— Low battery
Performing Auto EQ
p
Auto EQ changes the audio settings as follows:
— The fader/balance settings return to the center position.

Using balance adjustment on page 43
— “ Mute Level ” is set to “ Off ”.

Previous settings for Auto EQ will be overwritten.
p
Do not press to open or close the panel when you are
using the microphone.
CAUTION
Do not turn off the engine while the measurement is in
progress.
