SOUND FIELD PROGRAM PARAMETER EDITING
I 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
I 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
I 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
I 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.
