	LD and audio-only discs, DTS provides up to five separate main audio channels and a special
	dedicated low-frequency channel.
Dolby Pro Logic II	Dolby Pro Logic II is the latest version of Dolby Laboratory’s benchmark surround technology	Movies: 10ms – 25ms
Movies	that decodes full-range, discrete left, center, right, right surround and left surround channels	Music: 0ms – 15ms
Music	from either matrix surround-encoded programs or conventional stereo sources. The	Emulation: 10ms – 25ms
Emulation	Dolby Pro Logic II Movies mode is optimized for movie soundtracks, while the Pro Logic II
	Music mode should be used with musical selections. The Pro Logic II Emulation mode
	re-creates original Pro Logic processing for those who prefer that presentation.
Logic 7 C	Logic 7 is an advanced mode that extracts the maximum surround information from either	Delay time not adjustable
Logic 7 M	surround-encoded programs or conventional stereo material. The Logic 7 C, or Cinema, mode
	should be used with any source that contains Dolby Surround or similar matrix encoding.
	Logic 7 C delivers increased center-channel intelligibility, and more accurate placement of sounds
	with fades and pans that are much smoother and more realistic than with other decoding
	techniques. The Logic 7 M, or Music, mode should be used with analog or PCM stereo sources.
	Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater
	rear ambience. Both Logic 7 modes also direct low-frequency information to the subwoofer
	(if installed and configured) to deliver maximum bass impact.
Dolby 3 Stereo	Uses the information contained in a surround-encoded or two-channel stereo program to create	No surround channels
	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	The Theater mode creates a sound field that resembles the acoustic feeling of a standard	Delay time not adjustable
	live performance theater.
Hall 1	The two Hall modes create sound fields that resemble a small (Hall1) or medium-sized (Hall 2)	Delay time not adjustable
Hall 2	concert hall.
VMAx Near	When only the two front-channel loudspeakers are used, Harman’s patented VMAx mode delivers a three-	No surround channels
VMAx Far	dimensional sound space with the illusion of “phantom speakers” at the center and surround positions.
	The VMAx N, or Near Field, mode should be selected when your listening position is less than five feet
	from the speakers. The VMAx F, or Far Field, mode should be selected when your listening position is
	greater than five feet from the speakers. The VMAx modes are also available using the Headphone
	Jack 4. When headphones are being used, the Far Field mode will appear to push the sound field
	away from your ears, reducing the “inside the head” sensation often experienced when using headphones.

5-Channel Stereo	This mode takes advantage of multiple speakers to place a stereo signal at both the front and
	back of a room. Ideal for playing music in situations such as a party, it places the same signal
	at the front-left and surround-left, and front-right and surround-right speakers. The center
	channel is fed a summed mono mix of the in-phase material of the left and right channels.

No delay is available for this mode

Surround Off (Stereo)	These modes turn off all surround processing and present the pure left- and right-channel presentation	No surround channels
Stereo-Direct (Bypass)	of two-channel stereo programs. The Stereo-Direct (Bypass) mode may only be used with analog source
Stereo-Digital	inputs, as it preserves the analog format of the audio signal for its entire path of travel through the receiver
	to the speaker and subwoofer outputs, bypassing all digital processing. Digital bass management is not
	available in Stereo-Direct mode. The Stereo-Digital mode can be used with either an analog or digital input,
	as the signal undergoes digital bass management to optimize the distribution of the low frequencies
	between the main speakers and a subwoofer.
