DIGITAL AUDIO
To take advantage of the T 748’s high performance surround and digital
audio circuitry, it is advisable that its Digital Audio inputs are selected.
There are three types of Digital Audio input for the T 748. These are HDMI,
Optical and Coaxial digital inputs. A fourth option is “O” whereby no
incoming digital audio signal is selected by the particular Source.
The desired digital audio input for a particular Source can be selected by
scrolling to “Digital Audio”, press [ S ] and then [ D/F ] to step through the
desired digital input source. After nalizing the desired type of Digital Audio
input, press [ S ] and then [ D/F ] again to select the specic Digital Audio input.
The following are the sets of assignable Digital Audio input:
HDMI HDMI 1, HDMI 2, HDMI 3, HDMI 4
Optical Optical 1, Optical 2, Optical Fr
Coaxial Coaxial 1, Coaxial 2
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
There are four types of video input a particular Source could be assigned.
These are HDMI, Comp (Component), S-Vid (S-Video) and Video inputs. A
fth option is “O” wherein the particular Source is prompted not to select
any Video input.
Navigate through the Video input selections by pressing [ S ] and then
[ D/F ] to step through the selections. The following are the sets of
assignable Video input:
HDMI HDMI 1, HDMI 2, HDMI 3, HDMI 4
Component Video Comp 1
S-Video S-Vid 1, S-Vid Fr
Video Video 1, Video 2, Video Front
VIDEO FORMAT CONVERSION
The T 748 is equipped with a Video Format Converter. This allows for a
simplied video connection between the T 748 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 digital format, the video input signal could also be available at
the other Monitor output jacks including HDMI MONITOR OUT. Thus, you
do not have to necessarily assign the video output of a composite video
input signal to MONITOR OUT (Composite video). The composite video
input signal can be viewed also at HDMI MONITOR OUT at a resolution
setting dependent upon your TV/Monitor’s resolution capability. Some TV/
Monitors will automatically display the video signal at 480p/576p if they are
not capable of displaying 480i/576i.
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 section on “A/V Presets Setup” for
further understanding of Preset settings).
Scrolling to “A/V Preset” and by pressing [ S ] and then [ D/F ], 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”.
SOURCE SETUP (TABLE)
The Source Setup (Table) reects the settings made in the Source Setup
(Normal) menu. All the Source settings are summarized and displayed in
tabulated form in the Source Setup (Table).
Navigating through the Source Setup (Table) via a combination of [ A/S ]
and then [ D/F ] buttons, one will have the benet of directly changing the
settings for “Audio”, “Video”, “Preset” and “Source Name” without going back
to the Source Setup (Normal) menu.
Highlight a particular Source number and then, toggle [ENTER] button to
enable or disable said Source number.
iPod SETUP
The iPod Setup menu allows you to preset the following associated settings
when iPod is the selected source.
Enabled: Select “Yes” to enable iPod as a Source or “No” to disable it.
Auto Connect: Select “Yes” to automatically enable and connect the
iPod player docked in the linked NAD iPod docking station when Source
5 (the default iPod source allocation in the T 748) is selected. Select “No”
if you do not want a docked iPod to be automatically connected.
Menu Timeout: Set the time for the OSD to revert to the “Now
Playing” display when the iPod menu has been left idle (no scrolling or
navigation being done) for the specied time out time. For the “Now
Playing” OSD to be shown, there should be a song paused or being
played before going to the iPod menu. You can set the “Menu Timeout”
between the range 5s to 60s at 5s increments. If you do not want for the
menu to timeout, select “0s”.
