Surround Mode Chart

MODE	FEATURES	DELAY TIME RANGE
DOLBY DIGITAL	Available only with digital input sources encoded with Dolby Digital data. It provides	Center: 0 ms – 5 ms
	up to five separate main audio channels and a special dedicated Low-Frequency Effects	Surround: 0 ms – 15 ms
	channel.
DTS	Available only with digital input sources encoded with DTS data. Available on special	Delay not adjustable
	DVD, LD and audio-only discs, DTS provides up to five separate main audio channels and
	a special dedicated low-frequency channel.

DOLBY PRO LOGIC	The standard mode for analog surround sound decoding. It uses information encoded
	in a two-channel stereo recording to produce four distinct outputs: Left, Center, Right and
	a Mono Surround channel. 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.

15 ms – 30 ms

Initial Setting = 20 ms

LOGIC 7 C LOGIC 7 M

An advanced mode that extracts the maximum surround information from either	Delay time not adjustable
surround-encoded programs or conventional stereo material. When used with encoded
material, decoding is more accurate in terms of the placement of sounds, and fades and
pans are much smoother and more realistic than with other decoding techniques. Logic 7
also delivers increased spaciousness and a wider sound stage when it is used with con-
ventional stereo recordings and music programs. The Logic 7C or Cinema mode is tailored
to provide an optimal sound field for movie soundtracks. The Logic 7M or Music mode
uses a decoding formula that is best suited to music.

DOLBY 3 STEREO	Uses the information contained in a surround-encoded or two-channel stereo program to	No surround channels
	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 front-right
	channels for increased realism. Use this mode when you have a center-channel speaker
	but no surround speakers.

THEATER

VMAx

Surround processing uses matrix surround decoding to simulate a standard movie or	27.3 ms (not adjustable)
stage theater.
When only the two front-channel loudspeakers are used, Harman’s patented VMAx mode	No surround channels
delivers a three-dimensional sound space with the illusion of “phantom speakers” at the
center and surround positions.

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.
