Operation
This section focuses on operating the IN1501 using the front panel S-Video output controls.
The three switches provide easy access to advanced digital signal processing circuitry that
allows users to achieve optimal video display quality.
Note: The front panel controls are only functional in S-Video output applications.
FRONT PANEL CONTROLS
Color Bar Generator - acts as a video test signal and also allows operators to manually
adjust the hue of their display device. Turning the switch to the ON position will generate
the Color Bar output screen. Turning it OFF will return the unit to the S-Video output state.
The IN1501 is capable of generating color bars in both the NTSC
and PAL video standards. The unit senses the input signal and
adjusts automatically. If there is no video input signal present, the
IN1501 will generate color bars in the NTSC format.
Adaptive Comb Filter Switch - When this switch is set to the On position the adaptive
comb filter is selected. When the switch is in the Off position, the trap filter is selected.
Note: The comb / trap filter can be selected manually, however, if the IN1501 detects an
unstable incoming video signal that the comb filter will not easily adapt to (i.e. signals
containing artifacts, weak amplitude, large amounts of variability in the lumina signal, etc.),
the unit will automatically switch to the trap filter setting after about 10 seconds.
• The adaptive comb filter works best with equipment that outputs stable video
signals (DVDs, broadcast video recorders, test generators, etc.). The filter
electronically provides excellent Luma / Chroma separation (separates the color from
the picture signal). This greatly reduces cross-color interference and hanging dots
while maintaining image bandwidth and detail.
• The trap filter extracts luminance from the picture. While the trap filter may not
provide as much detail as the adaptive comb filter, it is usually the preferred setting
when running signals that are less than optimal quality (such as from a VCR). You
may wish to compare both settings to determine which is best for your application.
Noise Filter - reduces high-frequency noise (“snow”).
Power LED Indicator - illuminates when power is applied to the unit.
