• s-video (Y/C)

• RGsB or YUV

In addition, the FC-7402:

• Includes full ProcAmp control of the video via the front panel and
7-segment display, and via RS-232, with the option to store the settings in
non-volatile memory

• Has an internal 75% color bar generator, whose timing is based on the
SDI input

• Encodes 525 line signals to NTSC3.58 or NTSC4.43, and 625 lines to
PAL-B, D, G, H, I or Combination PAL-N. When encoding NTSC, it can be
programmed with or without a 7.5 IRE setup (pedestal)

• Can be controlled via a user-friendly Windows® based program that can
modify parameters such as hue, contrast, brightness, sharpness, and color

• Lets you store/recall up to 10 setups in non-volatile memory

To achieve the best performance:

• Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)

• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality

• Position your Kramer FC-7402 in a location free from moisture and away
from excessive sunlight and dust
