The D4E is useful for monitoring, level and phase checking, dubbing etc. The D4E automatically adapts to NTSC or PAL video standards and outputs analog NTSC (525 line inputs) or PAL (625 line inputs). Pedestal and narrow/wide H/V blanking are user configurable via dip-switches. The D4E encodes the full dynamic range of input video. Levels below black and above white are not clipped.
