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.
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.
Control range:	0 to 10

■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 the unit is using at least two front and two
	rear channels.
Control range:	1 to 49 msec

■S. ROOM SIZE (Surround room size)

Function:	This parameter adjusts the apparent size of the surround sound field.
Control range:	0.1 to 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 to 10

■RC. INIT. DLY (Rear center initial delay)

Function:	This parameter adjusts the delay between the direct sound and the first reflection in the rear center
	sound field.
Control range:	1 to 49 msec

■RC. ROOM SIZE (Rear center room size)

Function:	This parameter adjusts the apparent size of the rear center sound field.
Control range:	0.1 to 2.0

INFORMATION ADDITIONAL

■RC. LIVENESS (Rear center liveness)

Function:	This parameter adjusts the apparent reflectivity of the virtual wall in the rear center sound field.
Control range:	0 to 10
