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.

(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)

Using the automatic sound levelizer
During driving, noise in the car changes according to the driv-
ing speed and road conditions. ASL (automatic sound levelizer)
monitors such varying noise and automatically increases the
volume level, if this noise becomes greater. The sensitivity
(variation of volume level to noise level) of ASL can be set to one
of five levels.
1 Display the “Audio” setting screen.
 Refer to Displaying the “Audio” setting screen on page 68
2 Touch [ASL].
3 Touch the desired level.
