Adjusting the equalizer curve
automatically (Auto EQ)
By measuring the vehicle’s acoustics, the
equalizer curve can be adjusted automati-
cally 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 measure-
ment 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 measure-
ment (sold separately) is not placed in an
appropriate location, the measurement
tone may become loud and measure-
ment 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 from the vehicle
before performing Auto EQ. Sounds other
than the measurement tone (surrounding
sounds, engine sound, telephones ring-
ing, etc.) may prevent correct measure-
ment of the vehicle’s acoustics.
Be sure to perform Auto EQ using the
microphone for acoustical measurement
(sold separately). Using another micro-
phone 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,
a message appears and measurement
is canceled. 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:
— “Auto EQ&TA” is set to “On”.
For details, refer to Using the auto-ad-
justed equalizer on page 64.
— The fader/balance settings return to the
center position.
For details, refer to Using balance adjust-
ment on page 60.
— The equalizer curve switches to “Flat”.
For details, refer to Using the equalizer on
page 64.
— The front and rear speakers will automat-
ically be adjusted to a high pass filter
setting.
p Previous settings for Auto EQ will be
overwritten.
p Do not press the button to open or
close the panel when you are using the
microphone.
CAUTION
Do not turn off the engine while the mea-
surement is in progress.
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 canceled.
2 Fix the microphone for acoustical
measurement (sold separately) in
the center of the headrest of the
driver’s seat, facing forward.
The Auto EQ may differ depending on where
you place the microphone. If desired, place
the microphone on the front passenger seat
and perform Auto EQ.
3 Disconnect the iPhone or smart-
phone device.
4 Turn on the ignition switch (ACC
ON).
If the vehicle’s air conditioner or heater is
turned on, turn it off. Noise from the fan in
the air conditioner or heater may prevent
correct Auto EQ.
5 Switch the AV source to “OFF”.
For details of the operations, refer to
Displaying the AV operation screen on
page 12.
6 Press the HOME button to display
the Top menu screen.
7 Touch the following keys in the
following order.
The “Audio” screen appears.
8 Touch [A-EQ&TA Measurement].
The “A-EQ&TA Measurement” screen
appears.
9 Connect the microphone for acous-
tical measurement (sold sepa-
rately) with this product.
Plug the microphone into the microphone
input jack on this product.
10 Touch [Front Left] or [Front Right]
to select the current listening
position.
11 Touch [Start].
A 10-second countdown starts.
p The Bluetooth connection is discon-
nected before the process starts.
12 Exit the vehicle and keep the
doors closed until the countdown
finishes.
When the countdown finishes, a measure-
ment tone (noise) is emitted from the speak-
ers and the Auto EQ measurement begins.
13 Wait until the measurement is
completed.
When Auto EQ is completed, a message is
displayed indicating that the measurement
is completed.
