Input Settings - NAD VISO FIVE Owner's Manual

The following Listening Modes require a specially encoded signal that
must be present in digital format to be decoded by the VISO FIVE. These
modes are automatically switched on when the appropriate data stream is
detected. The desired data stream must sometimes be selected in the setup
menu of the source media.
DOLBY DIGITAL
Dolby Digital is the multi-channel digital signal format developed in the
Dolby laboratories. Discs bearing the double-D symbol were recorded with
up to 5.1 channels of digital signals, reproducing a much better sound
quality, with dynamic and spatial sound sensations that are much better
than in the previous Dolby Surround.
DYNAMIC RANGE CONTROL (DYN RANGE)
You can select the effective dynamic range (subjective range from soft
to loud) for playback of Dolby Digital soundtracks. For fully cinematic
effect, always select 100% - the default. Settings of 75%, 50% and 25%
progressively reduce dynamic range, making soft sounds comparatively
louder while limiting the peak loudness of loud ones.
The 100% setting is best for late-night sessions or other times when you
wish to retain maximum dialog intelligibility while minimizing overall
volume levels. To maintain full dynamic range, set "DYN Range" to "Off".
IMPORTANT NOTICE
"DYN Range" will appear as one of the options under the "Listening
Mode" menu only if the disc being played is of Dolby Digital format. The
same applies when you select the digital audio input (coaxial or optical)
as your audio source – Dynamic range adjustment will be available at
the "Listening Mode" menu only if the detected audio is of Dolby Digital
format. For Dolby Digital 2.0 soundtracks, set "Mode" at the "Listening
Mode" menu to "Dolby Digital 2Ch" ("DD 2Ch Stereo" if you toggle
[SURROUND MODE] button) for "DYN Range" option to appear.
DTS
The Digital Theater System Digital Surround (simply called DTS) is a multi-
channel digital signal format that can process higher data rates than with
Dolby Digital. Although both Dolby Digital and DTS are 5.1 channel media
formats, discs bearing the "DTS" symbol are thought to provide better sound
quality due to the lower audio compression required. It also offers a broader
dynamic, producing magnificent sound quality.
Downmix 2Ch: A Dolby Digital or DTS digital signal format can be
automatically downmixed to produce two-channel stereo audio.
DOLBY® HEADPHONE
Dolby Headphone technology, compatible with any pair of conventional
headphones, accurately simulates the experience of hearing a 5.1-channel
speaker system properly set up in a listening room, minus the annoying
"listener fatigue" effect that plagues other headphone-based virtual
surround sound offerings. Dolby Headphone technology is ideal for private
playback of multi-channel entertainment without disturbing others nearby.
Dolby Headphone models the sound of a playback system into three different
listening environments, based on acoustic measurements of real rooms:
DOLBY HP MODE 1 is a small, well-damped room appropriate for both
movies and music-only recordings. This decoding process is known as the
Dolby Headphone "Reference Room".
DOLBY HP MODE 2 is a more acoustically live room suited to music
listening, but also great for movies.
DOLBY HP MODE 3 is a larger room, more like a concert hall or movie
theatre.
Select DOLBY HP OFF for normal headphone audio listening.
USING THE VISO FIVE – AUDIO SETUP MENU

INPUT SETTINGS

INPUT
Aside from the VISO FIVE' s internal DVD, the VISO FIVE is also equipped with the
following audio/video source inputs - "Cable/Sat", "VCR" (iPod) and "Front" (Front
Input on the front panel). Another source input is the "Ext 5.1" which is an audio-
only input. The input becomes active whenever it is selected.
Use [ ] select through DVD, Cable/Sat, VCR (iPod), Ext 5.1 and then
back to DVD.
VIDEO IN
A particular video input can be assigned to any of the following source
inputs - Cable/Sat, VCR (iPod), Front and Ext 5.1. Ideally, a video input
present at the video input of a particular source input should be assigned
to the same source input. For example, a video input present at S-video
input of VCR should be the assigned video input for VCR source input. This
is actually the default setting. This can be varied though by assigning a
different active video input other than the particular source's default video
input setting.
AUDIO IN
Incoming digital and audio signals present at either digital or analog audio
are assignable to any of the following source inputs - Cable/Sat, VCR and
Front. Use [ ] to assign coaxial, optical or analog audio to any of the
aforementioned sources.
The assigned audio input will always be recalled whenever that input is
selected using the front panel INPUT SELECTOR knob or the HTR 7 remote's
input-select buttons.
It is not necessary to connect at the same time both analog audio and
digital audio input for every video input you employ. It is preferable to
make only digital audio link to the VISO FIVE for audio playback. This avoids
possible confusion and ensures that the VISO FIVE's high performance
digital audio circuitry will always be employed.
