RGB Input and AD Conversion
There are two sets of RGB inputs. Switching between them is done using the input button on the top of the
projector or the RGB1/2 button on the remote control.
Signal Board
The RGB signal goes through a RGB1/2 signal selector then the chroma signal (C) information is sent to the
video/RGB selector and the luminal signal (Y) information is sent to sync selection.
Driver Board
Refer to driver board information for video.
RGB Out
RGB out simply takes the information in its analog state and passes it through an amplifier to the terminal out.
Additional electronic image smoothing occurs in the gate array of the MP8610.
