SOUND FIELD PROGRAM PARAMETER EDITING SOUND FIELD PROGRAM PARAMETER EDITING
■ LIVENESS
Function: This parameter adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the
early reflections decay.
Control range: 0 – 10
Description:
The early reflections of a sound source decay much faster in a room with acoustically absorbent wall
surfaces than in one which has highly reflective surfaces. A room with acoustically absorbent surfaces
is referred to as “dead,” while a room with highly reflective surfaces is referred to as “live.” The
“LIVENESS” parameter lets you adjust the early reflection decay rate, and thus the “liveness” of the
room.

■ S.DELAY (surround delay)
Function: This parameter adjusts the delay between the direct sound and the first reflection in the surround sound
field.
Control range: 0 – 49 msec (The range depends on the signal format.)
■ S.INIT.DLY (surround initial delay)
Function: This parameter adjusts the delay between the direct sound and the first reflection on the surround side
of the sound field. You can only adjust this parameter when at least two front channels and two rear
channels are used.
Control range: 1 – 49 msec
■ S.ROOM SIZE (surround room size)
Function: This parameter adjusts the apparent size of the surround sound field.
Control range: 0.1 – 2.0
■ S.LIVENESS (surround liveness)
Function: This parameter adjusts the apparent reflectivity of the virtual walls in the surround sound field.
Control range: 0 – 10
