D (Dynamic). RANGE COMPRESSION
You can enjoy a powerful sound even at a low
volume level by compressing dynamic range
(difference between the lowest and the highest
frequency sounds).
• This takes effect for all the playback sources.
• OFF: Select when you want to enjoy
playback with its full dynamic range
(no effect applied).
• MID: Select when you want to reduce the
dynamic range a little.
• MAX:
Select when you want to apply the
compress effect fully (useful at a
low volume level).
SPEAKER SIZE
Set speaker information correctly.
• FRONT/CENTER/REAR:
Set the speaker size properly.
– LARGE: If the cone speaker size
is more than 13 cm.
– SMALL: If the cone speaker size
is less than 13 cm.
– NONE: If not used.

• SUBWOOFER:
Select "YES" (connected) or "NO"
(disconnected).
• SUBWOOFER PHASE:
Select either "NORMAL" or "REV.
(reverse)" to obtain better subwoofer
sounds.
• These settings are very related to one another;
therefore, one setting is changed, some other
settings will be changed automatically and
appropriately (see page 87).
• Sound comes out of the subwoofer for Dolby
Pro Logic II only when either the front speakers
or the center speaker is set to "SMALL."
CROSS OVER
You can select the crossover frequency for the
small speakers used. The signals below the
preset frequency level will be sent to the
subwoofer (or to the "LARGE" speakers when
"SUBWOOFER" is set to "NO").
AMP GAIN
You can change the maximum volume level of
this unit. When the maximum power of the
speakers is less than 50 W, select "LOW"
to prevent them from being damaged.
• HIGH: You can adjust the volume level
from "0" to "50."
• LOW:
You can adjust the volume level
from "0" to "30."
