NAD T737 - Page 19

DIGITAL AUDIO
To take advantage of the T 737’s high performance surround and digital
audio circuitry, it is advisable that its Digital Audio inputs are selected.
There are four Digital Audio inputs selectable for the T 737 - Opt 1
(Optical1), Opt 2 (Optical 2), Opt F (Optical Front) and Coax 1 (Coaxial 1).
Another option is “O” whereby no incoming digital audio signal is selected
by the particular Source.
NOTE
An incoming digital signal present at the assigned digital input will always
take precedence over the assigned analog audio input, even if both are
present. To maintain the analog audio input for the particular Source, select
“O” at the “Digital Audio” setting of the same “Source” menu.
VIDEO
A specic video input can be assigned a particular Source. The following are
the assignable Video inputs:
• HDMI 1, HDMI 2
• Comp 1-3 (Component 1-3)
• S-Video 1, S-Video 2, S-Video 3, S-Video 4, S-Video F (Front)
• Video 1, Video 2, Video 3, Video 4, Video Fr (Front)
Another option is “O” wherein the particular Source is prompted not to
select any Video input.
ABOUT VIDEO FORMATS
For many years, there was only one type of video format used. Composite
video signals include the Luminance (black & White) and Chroma (color)
signals combined on one wire. S-Video uses separate wires in a single cable
for Luminance and Chroma signals. Component Video goes a step further
with separate cables for Luminance and the two elements of Chroma. For
NTSC (America, Japan) as well as PAL signals (Europe, Asia) these are labeled
Y, Cr, Cb. Television studios use the Component Video format to keep these
signals separate in order to maintain the best quality. As consumer video
equipment has improved this higher quality format has been included.
VIDEO FORMAT CONVERSION
The T 737 is equipped with a Video Format Converter. This allows for a simplied
video connection between the T 737 and your TV Monitor when using multiple
video formats such as Composite (CVBS), S-Video, and Component (YUV). This
format change is accomplished by encoding the analog video signal into a
digital signal using a very high quality digital encoder to maintain the best
possible picture quality. Once in a digital format, it can be decoded into any of
the three standard analog video formats.
It is suggested that you select the highest quality video format available
on your TV Monitor and utilize this for your Monitor OUT connection from
the T 737 to the TV Monitor. In most cases this will be Component Video,
but on some older TV’s S-Video may be the best quality connection. See
also the item “COMPONENT VIDEO 1-3, COMPONENT VIDEO OUT” under
“Identication of Controls – Rear Panel” discussions.
NOTES
Video signals are converted between all three formats:
· Video (Composite), S-video and Component Video.
· All three monitor outputs will always be active no matter what the
source format is.
· OSD menu is always available on all three output formats - Video
(Composite), S-Video and Component Video.
A/V PRESET
A particular Source can be assigned a stored Preset. The parameters set up
in the selected Preset number will be adopted into the particular Source
it is assigned (Please refer to the separate item below about “AV PRESETS
SETUP” for a better understanding of A/V Preset settings).
Scrolling to “A/V Preset” and by pressing [ ] and then [ ] keys, a
Source could be assigned a Preset number ranging from Preset 1 to 5.
If it is desired not to assign the particular Source a Preset setting, select
“None”.
TRIGGER OUT
The Trigger Out for a particular Source is dependent on the congurations
done in a separate menu on Trigger Setup (See “TRIGGER SETUP” below).
If Trigger output is assigned to “Src Setup” in the separate “Trigger Setup”
menu window, +12V will be available at +12V TRIGGER OUT port whenever
a Source with “Trigger Out” set to “Yes” is recalled.
Another option is “No” whereby the particular Source is not assigned any
Trigger Out.
