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.

■S. ROOM SIZE (Surround Room Size)

Function	This parameter adjusts the apparent size of the surround sound field.
Control range	0.1 – 2.0
Description	The larger the value, the larger the surround sound field becomes.

■S. LIVENESS (Surround Liveness)

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.
