SOUND FIELD PROGRAM PARAMETER EDITING

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 – 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 – 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 – 10

REV.TIME (reverberation time)

Function:

This parameter adjusts the amount of time it takes for the dense, subsequent reverberation sound to
decay by 60 dB (at 1 kHz). This changes the apparent size of the acoustic environment over an
extremely wide range.

Control range: 1.0 – 5.0 sec
Description:

Set a longer reverberation time for “dead” sources and listening room environments and a shorter time
for “live” sources and listening room environments.
