OPERATION 27

DTS Neo:6 Cinema

These two modes are available when any analog source is playing to create a six-channel 

Delay time not adjustable

DTS Neo:6 Music

surround presentation from conventional Matrix-encoded and traditional Stereo sources. Select 
the Cinema version of Neo:6 when a program with any type of analog Matrix surround encoding 
is present. Select the Music version of Neo:6 for optimal processing when a nonencoded,
two-channel stereo program is being played.

Dolby Virtual Speaker Dolby Virtual Speaker technology uses a next-generation advanced algorithm to reproduce the 

No surround channels

Reference

dynamics and surround sound effects of a precisely placed 5.1-channel speaker system using only 

Wide

front left and right speakers. In the Reference Mode, the apparent width of the sound across 
the front image is defined by the distance between the two speakers. The Wide Mode 
provides a wider, more spacious front image when the two speakers areclose together.

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 Off (Stereo)

These modes turn off all surround processing and present the pure left- and right-channel 

No surround channels 

Surround Off (Bypass)  presentation of two-channel stereo programs. The Surround Off (Bypass) mode may only be 
DSP Surround Off 

used with analog source 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 Surround Off mode. The 
DSP Surround Off 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.

Dolby Headphone 

Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-speaker 

No surround channels

DH1 

surround-playback system. The DH1 mode creates headphone presentation that resembles a small,

DH2 

well-damped room and is appropriate for use with both movies and music-only recordings.

DH3 

The DH2 mode creates a more acoustically live room particularly suited to music listening.
The DH3 mode creates a larger room, more like a concert hall or movie theater.
