TECHNICAL HIGHLIGHTS LD100 TECHNICAL HIGHLIGHTS – The LD100 is far more than simply a “line doubler”. It is a truly unique product in the world of high performance video. The LD100 is actually a complex image processor that consists of three distinct components – all utilizing patented Faroudja technologies and engineered into one chassis; the SuperNTSC decoder , the Faroudja proprietary line doubler, and Faroudja’s innovative bandwidth expansion circuit that allows for the sharpening of image d

Every LD100 is subjected to an intense battery of QC and environmental tests. Then each unit is re-tested and re-calibrated for optimum performance. The component parts used in the LD100 are the finest available, ensuring long term consistent per- formance and reliability. This unique, quality oriented “Faroudja touch” can also be seen in the design of many of the LD100’s controls and features. 6) Brightness Level – Known as “Set-up” in the IMAGE SHARPNESS CONTROLS (2) broadcast industry, the B
