Yamaha RX-V4600 Rev. Time Reverberation time, Rev. Delay Reverberation delay, Large value = 5.0 s

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. 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
