Advanced sound configurations

Sound field parameter	Features
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

	Small value = 1.0 s				Large value = 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
