Digital Sound Field Parameter Descriptions
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.
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.
LIVENESS
Function .................... This parameter adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the early
reflections decay.
Control Range ........... 0 - 10
Description ................ The early reflections of a sound source decay much faster in a room with acoustically absorbent wall surfaces
than in one which has highly reflective surfaces. A room with acoustically absorbent surfaces is referred to as
“dead,” while a room with highly reflective surfaces is referred to as “live.” The LIVENESS parameter lets you
adjust the early reflection decay rate, and thus the “liveness” of the room.

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.
