DIGITAL SOUND FIELD PARAMETER DESCRIPTIONS

■S. DELAY (Surround Delay)

Function	This parameter adjusts the delay between the direct sound and the first reflection in the surround sound field.
Control range	0 – 49 ms (The range depends on the signal format.)
Description	When Dolby Digital signals are decoded: the larger the parameter, the later the surround sound source begins.
	When a non-Dolby Digital program is decoded: the larger the parameter, the later the surround sound field begins.
	No surround sound source is produced.

Function	This parameter adjusts the apparent reflectivity of the virtual walls in the surround sound field.
Control range	0 – 10
Description	The larger the value, the more reflective the surround sound field walls become.

■RC INI. 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 ms
Description	The larger the value, the later the first reflection begins.

■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
Description	The larger the value, the more reflective the presence sound field walls become.

■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
Description	The larger the value, the more reflective the surround sound field walls become.
