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:	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 sec

■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 msec
