Using the auto-adjusted
equaliser
You can set the auto-adjusted equaliser
to suit the vehicle’s acoustics. To use this
function, the vehicle’s acoustics must be
measured in advance.
For details of the operations, refer to
Adjusting the equaliser curve automati-
cally (Auto EQ) on page 48.

Adjusting the equaliser curve
automatically (Auto EQ)
By measuring the vehicle’s acoustics, the
equaliser 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 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 micro-
phone 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 mobile 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.
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,
a message appears and measurement
is cancelled. Check the following before
measuring the vehicle’s acoustics.

Rear speakers (left/right)

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-
adjusted equaliser on page 48.
—
The fader/balance settings return to the
centre position.
For details, refer to Using balance adjust-
ment on page 44.
—
The equaliser curve switches to “ Flat ”.
For details, refer to Using the equaliser on
page 47.
—
The front and rear speakers will auto-
matically 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 meas-
urement 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 dur-
ing measurement, measurement is
cancelled.
2 Fix the microphone for acoustical
measurement in the centre 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 10.
6 Press the HOME button to display
the Top menu screen.
