Editing surround decoders/sound field programs

Dialog Lift

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.

Parameter for CINEMA DSP 3D

3D DSP

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

Note

•

When the presence speakers are not used, the 3D DSP parameters are not 
displayed.

Parameters for adjusting early-reflected 
sound

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.

•

We recommend that you adjust the size of corresponding sound field 
when you adjust the delay time.

■

Parameters for specifying 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.
