3-29IN1404XT Video Scaler and Switcher • Operation

•Interlaced — Some video sources output interlaced video at rates that the scaler
interprets as progressive scan mode. This option lets you force the scaler to
recognize it as interlaced video.
•Swap Fields — Swaps the interlaced fields (if necessary). Although this option
can be turned on when the input is progressive, it has no affect on
progressive video.
•Invert Sync — To invert the sync polarity (if necessary).

Input Mode screen

The Input Mode screen is available for RGBHV, RGBS, RGsB, and progressive
component video inputs only.
The Input Mode screen identifies the currently selected input format detection
mode and provides the ability to select a different mode or to lock out changes.
Four options are available:
•Auto Detect — The default mode at power on. Allows the scaler to
automatically detect new input sampling rates and adjust itself accordingly.
•Lockout Changes — Prevents the scaler from switching back and forth
between input sampling rates, or flickering when small input sampling rate
changes occur (such as from a VCR that is scanning forward or scanning
backward).
•User Defined — All input sampling rates have the same user-definable
settings. However, the inputs are restricted to values that are close to the
sampling rate detected. If a full range of values is necessary, the user-defined
mode can be manually selected.
If the Auto Detect mode cannot determine the input sampling rate, the User
Defined mode is selected automatically.
•Redetect Now — The scaler automatically reconfigures when each new input
is detected and when each new output mode is detected. If the scaler does
not detect a change in the input sampling rate, or if the input/output settings
become invalid, the Redetect Now option allows users to initiate a new
detection sequence and reload the input/output settings.
To select a Input Mode option, use the Menu or button to highlight the desired
option and press the Enter (and save) button.
Optimizing the Audio
Each individual input’s audio bass, treble, and balance levels can be adjusted for
maximum sound quality. Adjust the audio as follows:
1. Connect audio sources to all desired inputs and connect the audio output to
output devices such as audio players. See Input connections and Standard
output connections, in chapter 2, Installation.
2. Power on the audio sources, the scaler, and the audio players.
3. Select an input, listening to the audio with a critical ear.
4. As necessary, adjust each variable for the input (see Audio menu, in this
chapter) for optimum audio quality.
5. Select each input in turn and repeat step 4 for each input.
