Surround Mode Chart

MODE	FEATURES	DELAY TIME RANGE
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	The THEATER mode creates a sound field that resembles the acoustic feeling of a	Delay time not adjustable
	standard live performance theater, with stereo and even pure mono sources.
HALL 1	The two Hall modes create sound fields that resemble a small (HALL1) or	Delay time not adjustable
HALL 2	medium sized (HALL 2) concert hall, with stereo and even pure mono sources.
VMAx Near	When only the two front-channel loudspeakers are used, Harman’s patented VMAx mode	No surround channels
VMAx Far	delivers a three-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 1,5 m from the speakers. The VMAx F, or “Far Field” mode
	may be selected when your listening position is greater than 1,5 m from the speakers.
	The VMAx modes are also available using the Headphones Output 4. When headphones
	are being used, the Far Field mode will 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	No delay available in
7-Channel Stereo	back of a room. Depending on whether the AVR has been configured for either 5.1 or 6.1/7.1	these modes
	operation, one of these modes, but not both, is available at any time. Ideal for playing music in
	situations such as a party, this mode places the same signal at the front-left and surround-left,
	and at the 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.
SURROUND	This mode turns off all surround processing and presents the pure left- and right-	No surround channels
OFF (STEREO)	channel presentation of two-channel stereo programs.
