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
CAUTION
Do not turn off the engine while the measurement is in

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 exam-
ple, 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

