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
