Overview
3 Overview
The Kramer DigiTOOLS 7408 SDI to Analog Converter is a high quality,
full 10-bit SDI to Analog video converter in a Kramer Tool housing. The
7408 SDI to Analog Converter is a multi-standard unit, converting 525-line
SDI to NTSC or NTSC4.43, and 625-line SDI to PAL-B/D/G/H/I/N.
The 7408 features:
• Reclocked and equalized SDI output (loop)
• 4 times digital over sampling to minimize digital artifacts
• Output configuration to Composite Video and s-Video (Y/C), or
component video (YUV)
• User-friendly Windows PC software, provided for ProcAmp
control via RS-232 for adjusting parameters such as contrast, hue,
saturation and sharpness
• NTSC encoding with or without a 7.5IRE setup
• A perforated cover to prevent overheating
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 and position your Kramer 7408
away from moisture, excessive sunlight and dust
