Automatically adjusting the
equalizer mode (Auto EQ)
You can measure the frequency characteristics
(value) in the vehicle to automatically adjust them
to the smooth characteristics with low distortion
based on the measurement data if the optional
measurement microphone (MEI-100) is
connected to this system. The measurement
result can be referred to when adjusting the
parametric equalizer.
ATTENTION
• Adjust Time Alignment (refer to page 71)
and Crossover (refer to page 73) before
measuring frequency characteristics.
• When measuring frequency characteristics,
Loudness setting is automatically
cancelled.
• Close all doors and windows while
measurement is in progress.
Measuring frequency characteristics
Align the microphone with the actual
ear position and attach it to the
headrest or other appropriate fixture.
(Attach the microphone using tape or
string.)
After pressing the button, a 10-second
countdown begins. Leave the vehicle
during that time.
After ten seconds, pink noise will be
output from the speakers and the
measurement of the frequency
characteristics will start. The
“Measuring" message appears on the
display while measurement is in
progress.
When the measurement is completed,
a "COMPLETED" message will appear
on the display. Then press the [Enter],
[ ], [ ], [>], [<] or [ /BAND]
button to go back to PEQ screen and if
necessary, adjust each band manually.
"Auto EQ" displayed on the screen
indicates that the measurement result
is active. If the measurement is
unsuccessful, a "FAILED" message
will appear on the screen. In this case,
go back to PEQ screen by pressing
the [Enter], [ ], [ ], [>], [<] or [ /
BAND] button and repeat the process.
You can cancel the measurement by
pressing the [ /BAND] button anytime
during a measurement process.

In order to make the measurement of
frequency characteristics easier, slight

under some circumstances when this
function is used. In addition, it is not
equivalent to the precise measurements
that can be made by specialist measuring
devices.

optional microphone (MEI-100) to
the L-CH of the AUX jack of the
