IN1404 User’s Manual 12
If the following settings seem confusing, we recommend that you experiment with the MENU ,
, , , and ENTER buttons until you familiarize yourself with the IN1402 front panel
control operations. It’s a good idea to get comfortable using these buttons to navigate through the
on-screen menu system before moving on to other sections of this manual. If you get lost, enter
unfamiliar territory or are afraid of making an improper selection, pressing the
MENU button
allows you to leave the menu system safely without making any changes. We also recommend,
unless you’re a qualified audiovisual technician, avoiding the Advanced menu.
Gamma:
The 30 active gamma correction curves programmed into the IN1404 are used to compensate
for the non-linear response of many display devices. Before you adjust Gamma, the brightness and
contrast controls should be set at factory default positions. Once the proper gamma setting has been
achieved, the brightness and contrast settings should then be optimized to fine tune the image.
Range : 1 to 30
Factory default setting : 10*
Operation :
Press button to step to higher numbered gamma curves.
Press button to step to lower numbered gamma curves.
* The factory default setting of 10 refers to a gamma correction curve of 1.0.
Noise Filter changes the input signal noise filter. This applies to composite, S-video and component A
signal formats only.
Range : 0 to 47
Factory default setting : 9
Operation :
Press button to increase noise filter.
Press button to decrease noise filter.
Increasing the noise filter setting produces the effect that the picture sharpness setting is
decreasing. See the
Sharpness section on the previous page.
Comb/Trap Filter selects either the comb or trap filter (only available with composite video). The
comb 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. This applies to composite, S-video and component A signal formats
only.
The trap filter extracts luminance from the picture. Generally speaking, the trap filter is usually the
preferred setting when running signals from a VCR (as composite video). You may wish to compare
both settings to determine which is best for your application.
Reset Video resets all video settings to factory default (for current input only).
