REV.TIME
Reverberation time. Adjusts the amount of time taken 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. 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 to 5.0 s
REV.DELAY
Reverberation delay. Adjusts the time difference between the beginning of the direct sound and
the beginning of the reverberation sound. The larger the value, the later the reverberation sound
begins. A later reverberation sound makes you feel as if you are in a larger acoustic environment.
Control range: 0 to 250 ms
REV.LEVEL
Reverberation level. Adjusts the volume of the reverberation sound. The larger the value, the
stronger the reverberation becomes.
Control range: 0 to 100%
