Input menu
To access the input menu via the front panel control buttons
1. Press the desired Input Select button.
2. Press MENU, press the
or button (if necessary) to reach the input menu.
3. Press ENTER.
4. Select the setting you wish to adjust by using the
and buttons and pressing ENTER.
5. Press ENTER to save once you’ve optimized the setting for the current input.
Input Signal Format: Select the signal format for each input. The S-video and Composite Video
connections are internally wired together. Therefore, only S-video or composite video can be
connected to each input, but not both at the same time. Input 4 is fixed as RGB passive.
To configure the Inputs 1 - 3 for either a composite video or S-video format:
1. Press the ENTER or MENU button to access the main menu.
2. Highlight INPUT and press ENTER to access the input menu (use the
and arrow buttons to
highlight the appropriate menu command).
3. Highlight SIGNAL FORMAT and press ENTER to access the signal format menu.
4. Highlight the input you want to configure.
5. Select the format for each individual input (use the
and buttons to toggle between composite
and S-video). The IN1403 will save the format setting automatically.
6. Press MENU to exit.
It is critical that the composite/S-video status is selected properly for each input. Using the
on-screen menu, you can set/change the input format at any time, even when another input signal
is active. If the composite/S-video selection is set incorrectly, the decoder circuitry will not
function properly and the IN1403 will display a distorted picture.
Aspect Ratio: The aspect ratio controls vary the relative image width and height. They can be used to
accommodate various input signal aspect ratios as well as output device aspect ratios. Select the
output aspect ratio by choosing the appropriate resolution in the output menu (see the output
resolution description on page 14).
Standard: For Standard 1.33 input signals (sometimes referred to as full screen)
Anamorphic: This setting provides vertical image squeezing to accommodate
anamorphically enhanced DVDs
Wide Screen: For wide screen 1.78 input signals (letterbox)
Wider Screen: For wider screen 2.35 input signals (narrow letterbox)
Tomarama: Designed for wide screen (letterbox) signals viewed on 4:3 aspect ratio
displays. Tomarama mode zooms in on the center of the image and crops
the image vertically and horizontally so that the black bars above and below
the image are removed. In this mode, some image is also lost on the right
and left hand edges.
Most DVDs and VCRs and other video sources output a signal with an aspect ratio of 4:3. How this
signal is filled with active video information determines its aspect ratio. In the following four
examples, four different input aspect ratios are shown on the left as they would be displayed in their
native 4:3 format. The same signals are shown on the right as they would appear on 4:3 and 16:9
display devices with the scaler set to various aspect ratios.
