■ 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.
Description: Set a longer reverberation time for “dead” sources and listening room environments, and a shorter time
for “live” sources and listening room environments.
Control Range: 1.0 – 5.0 sec
■ 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.
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.
Control Range: 0 – 250 msec
■ REV. LEVEL (Reverberation level)
Function: This parameter adjusts the volume of the reverberation sound.
Description: The larger the value, the stronger the reverberation becomes.
Control Range: 0 – 100%
