Surround Mode Chart

MODE	FEATURES	DELAY TIME RANGE
DOLBY DIGITAL	This mode is available only when the source material is encoded with Dolby Digital	Center: 0 ms – 5 ms
	(AC-3) data. It provides up to five separate main audio channels and a special	Surround: 0 ms – 15 ms
	dedicated Low-Frequency Effects channel.
DTS	This mode is available only when the source material is encoded with DTS data.	Center: 0 ms – 5 ms
	Available on special DVD, LD and audio-only discs, DTS provides up to five separate	Surround: 0 ms – 15 ms
	main audio channels and a special dedicated low-frequency channel.
DOLBY PRO LOGIC	Dolby Pro Logic is the standard mode for analog surround sound decoding. It uses	15 ms – 30 ms
	information encoded in a two-channel stereo recording to produce four distinct	Initial Setting = 20 ms
	channels: Left, Center, Right and Surround. Use this mode for accurate reproduction
	of programs bearing the Dolby Surround, DTS Stereo, UltraStereo or other
	“Surround” logos. Surround encoded programs include videocassette, DVD and LD
	movies, TV and cable programs, radio programs and audio CDs. Dolby Pro Logic
	processing may also be used to provide a pleasing surround effect with some
	stereophonic source material that does not carry surround encoding.
DOLBY 3 STEREO	Dolby 3 Stereo uses the information contained in a surround encoded or two-channel	No Surround Channels
	stereo program to create center channel information. In addition, the information
	that is normally sent to the rear channel surround speakers is carefully mixed in with
	the front left and right channels for increased realism. Use this mode when you have a
	center channel speaker, but no surround speakers.
THEATER	Theater Surround processing uses matrix surround decoding to simulate a standard	27.3 ms
	movie or stage theater.
HALL 1 and HALL 2	These modes are designed for use with stereo recordings. They provide a sound-field	Hall 1 – 41.6 ms
	effect that simulates the complex combination of direct and reflected sounds that	Hall 2 – 67.4 ms
	create the rich reverberant atmosphere of a medium-sized concert hall (Hall 1) or a
	larger concert hall (Hall 2).
STEREO	This mode turns off all surround processing and presents the pure left and right	No Surround Channels
	channel presentation of two channel stereo programs.
