Performing Auto Eq - Pioneer AVIC-F77DAB Operation Manual

Audio adjustments
! 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 fre-
quency.
! The distance has been calculated by a
computer to provide optimum delay to en-
sure accurate results. Do not change this
value.
— The reflected sound within the vehicle is
strong and delays occur.
— The LPF on active subwoofers or exter-
nal amps delay the lower sounds.

message appears and measurement is
cancelled. Check the following before mea-
suring the vehicle's acoustics.
— Front speakers (left/right)

ment (sold separately)

CAUTION
Do not turn off the engine while the measure-
ment 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 cancelled.
2 Fix the microphone for acoustical mea-
surement (sold separately) in the centre of
the headrest of the driver's seat, facing for-
ward.
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 smartphone
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.
Switch the AV source to "OFF".
