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 Press AUDIO to select HP-FILTER.
2 Press a to turn high pass filter on.
HP-FILTER 80 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 HP-FILTER 80.
# To turn high pass filter off, press b.
3 Press c or d to select cut-off frequency.
50—63—80—100—125 (Hz)
Only frequencies higher than those in the se-
lected range are outputted from the front or
rear speakers.

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 Press AUDIO to select BASSBOOSTER.
# You can also select the bass boost setting by
pressing and holding SW.
2 Press a or b to select a desired level.
0 to +6 is displayed as the level is increased or
decreased.

Front image enhancer (F.I.E.)

The F.I.E. (Front Image Enhancer) function is a
simple method of enhancing front imaging by
cutting mid- and high-range frequency output
from the rear speakers, limiting their output to
20
En
low-range frequencies. You can select the fre-
quency you want to cut.
Precaution
When the F.I.E. function is deactivated, the rear
speakers output sound of all frequencies, not just
bass sounds. Reduce the volume before disenga-
ging F.I.E. to prevent a sudden increase in vo-
lume.
1 Press AUDIO to select FIE.
# When the rear output setting is REAR SP S/W,
you cannot select FIE.
2 Press a to turn F.I.E. on.
# To turn F.I.E. off, press b.
3 Press c or d to select a desired fre-
quency.
100—160—250 (Hz)
Notes
! After turning the F.I.E. function on, use the bal-
ance adjustment (refer to page 18) and adjust
front and rear speaker volume levels until they
are balanced.
! Turn the F.I.E. function off when using a 2-
speaker system.

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 Press AUDIO to select SLA.
