DIGITAL SOUND FIELD PARAMETER DESCRIPTIONS

■ S. DELAY (Surround Delay)

Control Range 0 – 49 msec (The range

depends on the signal format.)

Function:

This parameter adjusts the delay between the direct sound and the surround sound.

■ S. INIT. DLY (Surround Initial Delay)

Control Range 1 – 49 msec

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.

■ S. ROOM SIZE (Surround Room Size)

Control Range 0.1 – 2.0

Function:

This parameter adjusts the apparent size of the surround sound field.

■ S. LIVENESS (Surround Liveness)

Control Range 0 –10

Function:

This parameter adjusts the apparent reflectivity of the virtual walls in the surround sound field.

■ RC INIT. DLY (Rear Center Initial Delay)

Control Range 1 – 49 msec

Function:

This parameter adjusts the delay between the direct sound and the first reflection in the rear center
sound field.

■ RC ROOM SIZE (Rear Center Room Size)

Control Range 0.1 – 2.0

Function:

This parameter adjusts the apparent size of the rear center sound field.

■ RC LIVENESS (Rear Center Liveness)

Control Range 0 – 10

Function:

This parameter adjusts the apparent reflectivity of the virtual wall in the rear center sound field.

■ LIVENESS

Control Range 0 – 10

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.
