Boosting The Bass; Using The High Pass Filter; Adjusting Source Levels; Using Automatic Sound Levelizer - Pioneer DEH-P7900UB Operation Manual

Operating this unit
Only frequencies lower than those in the se-
lected range are outputted from the subwoo-
fer.
3 Push MULTI-CONTROL up or down to
adjust the output level of the subwoofer.
Each time MULTI-CONTROL is pushed up or
down, subwoofer level increases or decreases.
+6 to –24 is displayed as the level is increased
or decreased.

Boosting the bass

Bass boost function boosts the bass level of
sound lower than 100 Hz. The more the bass
level is increased, the more the bass sound is
emphasized and the entire sound becomes
powerful. When using this function with the
subwoofer, the sound under the cut-off fre-
quency is boosted.
1 Use MULTI-CONTROL to select Bass.
# You can also select the bass boost setting by
pressing and holding SW.
2 Push MULTI-CONTROL up or down to
select a desired level.
0 to +6 is displayed as the level is increased or
decreased.

Using the high pass filter

When you do not want low sounds from the
subwoofer output frequency range to play
from the front or rear speakers, turn on the
HPF (high pass filter). Only frequencies higher
than those in the selected range are outputted
from the front or rear speakers.
1 Use MULTI-CONTROL to select HPF.
2 Press MULTI-CONTROL to turn high
pass filter on.
80Hz appears in the display. High pass filter is
now on.
# If the high pass filter has been previously ad-
justed, the frequency of that previously selected
will be displayed instead of 80Hz.
# To turn high pass filter off, press
MULTI-CONTROL again.
3 Push MULTI-CONTROL left or right to
select cut-off frequency.
Each time MULTI-CONTROL is pushed left or
right, cut-off frequencies are selected in the
following order:
50Hz—63Hz—80Hz—100Hz—125Hz
Only frequencies higher than those in the se-
lected range are outputted from the front or
rear speakers.

Adjusting source levels

SLA (source level adjustment) lets you adjust
the volume level of each source to prevent ra-
dical changes in volume when switching be-
tween sources.
! Settings are based on the FM tuner volume
level, which remains unchanged.
1 Compare the FM tuner volume level
with the level of the source you wish to ad-
just.
2 Use MULTI-CONTROL to select SLA.
3 Push MULTI-CONTROL up or down to
adjust the source volume.
Each time MULTI-CONTROL is pushed up or
down, source volume increases or decreases.
SLA +4 to SLA –4 is displayed as the source
volume is increased or decreased.
Notes
! The MW/LW tuner volume level can also be
adjusted with source level adjustments.
! The built-in CD player and the multi-CD player
are set to the same source level adjustment
volume automatically.
! External unit 1 and external unit 2 are set to
the same source level adjustment volume
automatically.

Using automatic sound levelizer

During driving, noise in the car changes ac-
cording to the driving speed and road condi-
tions. The automatic sound levelizer (ASL)
monitors such varying noise and automati-
cally 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.
