AUDIO SETUP MENU
LISTENING MODE
The VISO FIVE offers distinct SURROUND MODES tailored for different types
of recordings or program material. With a two-channel (Stereo) source, the
following listening modes can be selected:
PRO LOGIC PLII
Dolby Pro Logic II is a more recent evolution of the original Dolby Pro Logic
surround processing that yields more stable imaging and full bandwidth
sound to the rear channels in Movie mode, offering sound that is more
similar to Dolby Digital decoding. Two-channel recordings, whether stereo
or surround-encoded, are reproduced with Dolby Pro Logic II surround
processing, yielding output to Front, Center and Surround channels
(assuming these are present in the “Speaker Settings” menu).
PLII Movie
is optimized for film soundtracks.
PLII Emulation
for decoding original Dolby Surround sound film and music
recordings.
PLII Music
for music recordings.
DIMENSION (-3 to +3): Adjusts front-rear emphasis of the surround
effect independently from the relative channel levels.
CENTER WIDTH (0 to 7): Modifies the “hard-centeredness” of the center
image, by gradually mixing mono center content to the Front left/right
speakers as well. A setting of 0 retains the center-channel-only default
while a setting of 7 yields a fully phantom center channel.
PANORAMA (On/Off ): Adds a “wrap around” effect by extending some
stereo content into the surround channels.
EARS
Two-channel recordings, whether stereo or surround-encoded, are
reproduced with proprietary NAD surround processing with signals
output to the front, center and discrete surround channels, plus subwoofer
(assuming these are present in the “Speaker Settings” menu).
EARS extracts the natural ambience present in nearly all well-produced
stereo recordings. It does not synthesize any ambience or other sonic
elements and thus remains truer to the sound of the original musical
performance than most other music-surround options.
Select EARS for listening to stereo music recordings and broadcasts.
EARS produces a subtle but highly natural and believable ambience from
nearly all “natural-acoustic” stereo recordings. Typically, these include
classical, jazz, and folk genres as well as numerous examples from others.
Its virtues include realistic, stable “front-stage” sonic imaging and spacious
but unexaggerated ambient “virtual acoustics” that remain faithful to the
original recording.
ENHANCED STEREO
All recordings reproduced in stereo via the maximum speaker complement
configured in the “Speaker Settings” menu. Enhanced stereo can be useful
for maximum volume from all channels or for multi-speaker background
music (cocktail party) listening. For this mode, Front, Center and Surround
can be turned “On” or “Off” as desired.
DOLBY® VIRTUAL SPEAKER (DVS)
Dolby Virtual Speaker technology creates a highly compelling 5.1-channel
listening experience from as few as two speakers, making it an ideal
entertainment solution for locations where space for multiple-speaker
setups is limited.
Dolby Virtual Speaker models the sound of a playback system into two
different listening environments, based on acoustic measurements of real
rooms:
DVS Reference is a small, well-damped room appropriate for both
movies and music-only recordings.
DVS Wide is a larger room, more like a concert hall or movie theatre.
STEREO
All output is directed to the front left/right channels. Low frequencies are
directed to the subwoofer if one is present in the Speaker settings. Select
“Stereo” when you wish to listen to a stereo (or monaural) production, such
as music CD or FM broadcast, without surround enhancement. Stereo
recordings whether in PCM/digital or analog form and whether surround-
encoded or not encoded, are reproduced as recorded. Multi-channel digital
recordings (Dolby Digital and DTS) are reproduced in “Stereo Downmix”
mode via the front left/right channels only as Lt/Rt (left/right-total) signals.
