SOUND FIELD PARAMETER DESCRIPTIONS
■ REV. TIME (Reverberation time)
Function: 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: The longer the reverberation time, the more live the listening room environment seems. The shorter the
reverberation time, the more dead the listening room environment seems.
Control range: 1.0 to 5.0 s
■ REV. LEVEL (Reverberation level)
Function: Adjusts the volume of the reverberation sound.
Description: The larger the value, the stronger the reverberation becomes.
Control range: 0 to 100%
■ REV. DELAY (Reverberation delay)
Function: 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 to 250 ms
