Editing surround decoders/sound field programs Dialog Lift Choices: 0* to 5 Adjusts the vertical position of center sound such as dialogues when presence speakers are used. Increasing this parameter raises the position. The ideal dialog position If the dialog seems to come out from a lower position than the video monitor screen, increase this parameter. 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. Original source sound Early-reflected sound Level Level Delay Time Delay Time Sound source Move up to the ideal dialog position "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. Sound field parameters for the advanced configurations 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 Parameter Init.Dly P.Init.Dly S.Init.Dly SB Init.Dly Adjustable range 1 to 99ms 1 to 99ms 1 to 49ms 1 to 49ms Reflecting surface Small = 1ms Large = 99ms y • We recommend that you adjust the size of corresponding sound field when you adjust the delay time. ■ Parameters for specifying room size Parameter Room Size P.Room Size S.Room Size SB Room Size Adjustable range 0.1 to 2.0 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. 50 En
