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.
