Using dynamic range control
The dynamic range refers to the difference be-

this difference so that the sounds can be
heard clearly even at low volume levels.

Refer to Introduction of DSP adjustments on
page 33.

Adjusting source levels
With SL A (source level adjustment), the vo-
lume levels of each source can be adjusted to
prevent significant differences between

! Settings are based on the FM volume level,
which remains unchanged.

level of the source you wish to adjust.
2 Use M.C. to select SLA in the audio
function menu.
Refer to Introduction of DSP adjustments on

tically set to the same source level adjustment
volume.

Setting the speaker setting
Be sure to adjust the speaker settings, such

if the speaker is capable of reproducing
sounds of about 100 Hz and below. Otherwise,
select SML (small).
! Low frequency sound is not emitted if the
subwoofer is set to OFF and the front and
rear speakers are set to SML or OFF.
! It is imperative that speakers that are not
installed be set to OFF.
! Set the front or rear speaker to LRG if the
speaker is capable of reproducing bass
content, or if no subwoofer is installed.

ting) in the audio function menu.
Refer to Introduction of DSP adjustments on
page 33.
2 Press c or d to select the speaker to be
adjusted.
FRONT (front speakers)—CENTER (center
speaker)—REAR (rear speakers)—SUB.W
(subwoofer)—PHASE (subwoofer setting)
# You can only switch to PHASE when the sub-
woofer has been set to ON.

for the selected speaker.
OFF (off)—SML (small)—LRG (large)

(normal phase) when PHASE (subwoofer setting)
has been selected.
Correcting the subwoofer’s phase

fer is not effective or you feel that the bass is
becoming less clear, the subwoofer output
and bass content emitted from the other
speakers may be canceling each other out.

ting) in the audio function menu.

page 33.

Selecting a cross-over frequency
The frequency under which sounds are repro-
duced through a subwoofer can be selected.
For example, if the size of one of the installed
speakers is set to SML, you can select the fre-
quency under which sounds will be repro-
duced through a speaker set to LRG or a
subwoofer.
