Choosing Theater-Dimensional Mode
Theater-Dimensional mode is the technology which controls the characteristics of the sounds reaching the listener’s left and right
ears, therefore, there is a sweet spot where you can best experience the Theater-Dimensional effects. You need to adjust the
location of the sweet spot and these other factors for the best possible Theater-Dimensional effect.
The listening angle is the angle at the listening position where the two lines from the left and
right speakers meet.
You need to adjust the listening angle in the following cases:
• If you set “Speaker 2ch” or “Speaker 3ch” in “Speaker Setup” on page 17.
Consider the listening angle as being formed from the left and right
front speakers since the
virtual surround signals are output from the front speakers.
• If you cannot place the surround speakers in the correct position.
– Place each surround speaker on top of or on the outer side of each front speaker of the
same side.
– Consider the listening angle as being formed from the left and right
surround speakers since
the virtual surround signals are output from the surround speakers.
Set “Lisng. Angle” to one of the following settings, which you feel is most effective (the listening
angles in parentheses are the ideal degrees):
• Normal (30°)
• Wide (40°)
• Narrow (20°)
The longer the distance
between the two speakers is,
the wider the angle is.
Balance mode
(“Balance” appears in the
display.)
The listener should be on the center line between the left and right speakers. But if the situation
does not allow you to sit in such an ideal position, you can adjust the balance.
Set “Balance” to one of the following 11 values, which you feel is most effective:
R+5, R+4, R+3, R+2, R+1, 0, L+1, L+2, L+3, L+4, and L+5.
The following tips may help you select the value:
• If the listener sits on the center line, then the factory setting “0” should be set as the balance, and
• If the listener sits on the right side of the center line towards the front speakers, select “L+.”
If the listener sits on the left side, select “R+.” A larger value should be selected as the
listening position becomes farther from the center line.
Notes
• The effect obtained with the balance adjustment may become less effective compared to the effect you
obtain when you are actually on the center line.
• If the listening position is too far from the center line, the balance adjustment may not be able to correct
the balance completely.

Corner mode
(“Corner” appears in the display.)
Theater-Dimensional controls the direct sounds from the speakers not the sounds reflected
from the walls. Therefore, if the distances between the speakers and the walls are too short
such as when the speaker system is placed in the corner of the room, and because of it, the
reflected sounds reach the listener’s ears too soon, the reflected sounds interfere with the
virtual surround sounds.
In such a case, set “Corner” to “On,” then the
CORNER indicator lights up in the display.
This may enhance the sound depending on the
situation.
(The factory setting is “Off,” which is the normal mode.)
Note
If the virtual surround sound is not enhanced with the corner mode, change the speaker positioning or
cover the walls with acoustic materials.
Dialog mode
(“Dialog Mode” appears in the
display.)
Listening angle
(“Lisng. Angle” appears in the
display.)
The dialog in the film may sound less clear because of the music or other sounds depending on
the movie or scene.
In such a case, set “Dialog” to “Enhance.” (The factory setting is “Normal” which is the normal
mode.)
Notes
• This function emphasizes the dialog in the center channel since the dialog sound, in most films, is
allocated to the center channel. Therefore, if the dialog is not in the center channel, the sound will not be
enhanced.
• Depending on the type of source, this mode is not very effective.
