LIVENESS

Function:

Description:

Control range:

This parameter adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the

early reflections decay.

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 surround sound. (Control range
	varies	depending	on	programs.)
Control range:	varies	depending	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 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

•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
