DIGITAL SOUND FIELD PARAMETER DESCRIPTIONS

■ 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
