Editing surround decoders/sound field programs
Dialog Lift
Choices: 0* to 5
Use this feature to adjust the vertical position of the
dialogues in movies. The ideal position of the dialogues is
at the center of the video monitor screen.
If the dialogues are heard at the lower position of the video
monitor screen, increase the value of "Dialog Lift."
When the value is set to zero, the position is at the lowest.
The position gets higher as you increase the value.
Notes
• "Dialog Lift" is displayed only when the presence speakers are available.
• You cannot the move the dialogue position loser than the default setting.

When CINEMA DSP 3D is enabled, sets whether to use
sound field programs in 3D mode.
Note

Adjustable range
Adjusts attenuation characteristics of early-reflected
sound. You can create a lively sound field (with a high
reverberant sound level) as you increase the value, and a
dead sound field (with a low reverberant sound level) as
you decrease the value. Creating either a lively sound field
or a dead sound field in an actual music hall is determined
by the acoustic absorption characteristics of reflection
surfaces. A dead sound field is created when the
attenuation time is short while a lively sound field is
created when the attenuation time is long.

Parameters for specifying room size
Parameter
Room Size, 0.1 to 2.0
P.Room Size,
S.Room Size,
SB Room Size
Produces different senses of sound expansion according to
room sizes specified. In a large size room such as a music
hall, the duration from when reflected sound is heard until
when the next reflected sound is heard is long. Thus,
different senses of sound expansion can be created by
changing the duration. 1.0 is the original room size. When
this parameter is set to 2.0, each side of the room is
defined as twice larger than the original room size.
