Carrying Out Auto Ta And Eq - Pioneer DEH-P88RSII Operation Manual

Section
12 Audio Adjustments
! When this unit is connected to a power
amp with input level control, auto TA and
EQ may not be possible if you lower power
amp input level. Set the power amp's input
level to the standard position.
! When this unit is connected to a power
amp with an LPF, turn off the LPF on the
power amp before carrying out auto TA and
EQ. In addition, the cut-off frequency for
built-in LPF of an active subwoofer should
be set to the highest frequency.
! The time alignment value calculated by
auto TA and EQ may differ from the actual
distance in the following circumstances.
However, the distance has been calculated
by computer to be the optimum delay to
give accurate results for the circum-
stances, so please continue to use this
value.
— When the reflected sound within a vehi-
cle is strong and delays occur.
— When delays occur for low sounds due
to the influence of the LPF on active
subwoofers or external amps.
! Auto TA and EQ changes the audio settings
as below:
— The fader/balance settings return to the
center position. (Refer to page 57.)
— The graphic equalizer curve switches to
Flat. (Refer to page 65.)
— When a subwoofer is connected to this
unit, it will be adjusted automatically to
both subwoofer output and high pass fil-
ter setting for rear speaker.
! If you carry out auto TA and EQ when a pre-
vious setting of this already exists, the set-
ting will be replaced.
! When connecting tweeters, please confirm
the tweeter's usable frequency range.
When you set the cut-off frequency, set
higher than the lowest usable frequency of
the tweeter.
! Auto TA uses higher range than 10 kHz for
measurement. Therefore, using the tweeter
that cannot reproduce 10 kHz frequency
68
En
range may damage the tweeter. When Auto
TA&EQ is operated, be sure to set the ap-
propriate cut-off frequency. Also, use the
tweeter that can reproduce 10 kHz at the
lowest usable frequency.

Carrying out auto TA and EQ

1 Stop the car in a place that is as quiet
as possible, close all doors, windows and
the sun roof, and then turn the engine off.
# If the engine is left running, engine noise may
prevent correct auto TA and EQ.
2 Fix the supplied microphone in the cen-
ter of the headrest of the driver's seat, fa-
cing forward, using the belt (sold
separately).
# The auto TA and EQ may differ depending on
where you place the microphone. If desired, place
the microphone on the front passenger seat to
carry out auto TA and EQ.
3 Turn the ignition switch to ON or ACC.
# If the car's air conditioner or heater is turned
on, turn it off. Noise from the fan in the air condi-
tioner or heater may prevent correct auto TA and
EQ.
# Press SOURCE to turn the source on if this
unit is turned off.
