Dialog Lift
Adjusts the vertical position of center sound such as
dialogues when presence speakers are used. Increasing
this parameter raises the position.
If the dialog seems to come out from a lower position than
the video monitor screen, increase this parameter.
“0” (default) corresponds to the lowest position and “5” to
the highest position.
Notes
• “Dialog Lift” is displayed only when the presence speakers are available.
• You cannot move the dialog position lower than the default setting.
y
• Some sound field programs have parameters for adjusting specific sound
fields. The following letters are displayed next to the names of those
parameters.
– P (presence sound field)
– S (surround sound field)
– SB (surround back sound field)
■ Parameters for adjusting early-reflected
sound
Adjust 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.
y
• We recommend that you adjust the size of corresponding sound field
when you adjust the delay time.
■ Parameters for specifying room size
Produce 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.
