5. CONCERT VIDEO:
This program produces an enthusiastic atmosphere and lets you
feel that you are in the midst of the action, as if attending an
actual jazz or rock concert.
The indirect sound constituent spreads on the surround side of
the sound field by the use of data of a large round hall for the
surround side, so the image space around the screen and the
sound space are fully expanded.
6. OPERA:
This program provides excellent depth of vocals and overall
clarity, restraining excessive reverberation.
For opera, the orchestra pit and the stage are ideally combined,
letting you feel a full presence sound. The rear surround side of
the sound field is relatively moderated, however, it reproduces
beautiful sound by the use of the data of a concert hall. You will
not be tired from long watching of an opera.

7. CLASSIC FILM:
This program is for reproducing monaural video sources (old
movies etc.). Monaural sounds are reproduced with much
presence by the front presence side of the sound field and
optimum reverberation effect. The use of the center speaker
makes conversations more audible, obtaining a pleasant mix of
conversations and picture.
8. ANIMATION:
Powerful reverberations on the front presence side of the sound
field adds depth to the image, so expanding the image space. On
the rear surround side, sounds are reproduced lightly but vividly.
The sound field of this program matches image effects of
animated films regardless of the genre. Conversations, sounds
and sound effects are reproduced with vitality by this program. A
source in stereo will obtain more effect, letting you steep yourself
in a fantastic world of animations.
