7. ENTERTAINMENT
Stadium: This program gives you long delays
between direct sounds and effect sounds,
and extraordinarily spacious feel of a large
stadium.
Disco: This program recreates the acoustic
environment of a lively disco in the heart of
a very lively city. The sound is dense and
highly concentrated. It is also characterized
by a high-energy, "immediate" sound.
8. TV THEATER
Drama: The data of the sound field of a relatively
narrow space is used for the front presence
side. A moderately sized spatial sound field
without excessive sound extension and
reverberations gives reality to the characters
in a drama.
The data of the sound field of an opera
house is used for the rear surround side. In
a stereo program, background music is
reproduced more beautifully with much
depth, enhancing sound effects on the
drama. It's natural sound effect will not make
you tired from long watching.
Variety/Sports: Though the front presence side of the sound
field is relatively narrow, the rear surround
side employs the sound environment of a
large concert hall. With this program, you
can enjoy watching various TV programs
such as the news, variety shows, music
programs or sports programs. In a stereo
broadcast of a sports game, the
commentator is oriented at the center
position, and the shouts and the atmosphere
in the stadium spreads on the surround side,
however, spreading of them to the rear side
is properly restrained.
