Digital Sound Field Parameter Descriptions
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 seconds
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)
Function .................... This parameter adjusts the time difference between the beginning of the direct sound and the beginning of the
reverberation sound.
Control Range ........... 0 - 250 milliseconds
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.

REV. LEVEL (Reverberation Level)
Function .................... This parameter adjusts the volume of the reverberation sound.
Control Range ........... 0 - 100%
Description ................ The larger the value, the stronger the reverberation becomes.
