After the input signals are amplified by the HY/HZ and HX boards the desired 
signal is selected. The microprocessor sends the command via the IIC bus to the 
input select switch (IC3001). The video switch selects from one of the three 
inputs. The component video signal output from the video switch is amplified and 
converted to digital. An optional Digital Visual Interface (DVI) input bypasses the 
A/D process as DVI information is already in the digital format.  
 
Concurrently, the desired sync signals are selected and applied to the Sync 
Processor. NTSC and Component sync signals are stripped from the Green 
video component while the PC sync is applied directly. The Sync Processor 
combines the On-Screen Display Sync signal with the input sync and converts 
them to match the video format.  
 
The corresponding audio signal is selected by an Audio switch and applied to the 
Z board for further amplification
