S. LIVENESS (Surround Liveness) Control Range 0 –10
Function .............. This parameter adjusts the apparent reflectivity of the virtual walls in the surround sound field.
RC. INIT. DLY (Rear Center Initial Delay) Control Range 1 – 49 msec
Function .............. This parameter adjusts the delay between the direct sound and the first reflection in the rear center sound field.
RC. ROOM SIZE (Rear Center Room Size) Control Range 0.1 – 2.0
Function .............. This parameter adjusts the apparent size of the rear center sound field.
RC. LIVENESS (Rear Center Liveness) Control Range 0 – 10
Function .............. This parameter adjusts the apparent reflectivity of the virtual wall in the rear center sound field.
REV. TIME (Reverberation Time) Control Range 1.0 – 5.0 sec
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.
Description ......... Set a longer reverberation time for “dead” sources and listening room environments, and a shorter time for “live”
sources and listening room environments.
REV. DELAY (Reverberation Delay) Control Range 0 – 250 msec
Function .............. This parameter adjusts the time difference between the beginning of the direct sound and the beginning of the
reverberation sound.
Description ......... The larger the value, the later the reverberation sound begins. A later reverberation sound makes you feel like you are
in a larger acoustic environment.
