The hardware for the EMP-TW1000 can basically be divided into two sections: the optical
engine and the circuit system. This section of the manual describes functions of the major
hardware components.
The components and unit in the dotted frame shown in the diagram below make up an optical
engine and MA Board Kit, which is provided as one part.
Overview of Display Operation

S-Video signals are provided to the MA Board from the CVBS input or S-Video port.
Analog signals are converted to digital signals at the MA board.
2. The digital display signals are temporarily stored in video memory on the MA board.
3. The R, G and B light valves control the amount of light that passes through the valves.
4. The light that passes through the light valves is combined by the prism and projected as an
image through the projection lens unit.
