Worksheet example 3: Test configuration
The A/V system in our fictional organization needs to be fine tuned on a regular
basis. Figure 3-9 shows a typical test configuration, with an Extron video test
generator (inputs 8 and 13) connected to each video group. Each VTG generates a
test pattern of the appropriate resolution to all connected outputs. Sound checks
are run from the CD player (input 14) to both output devices that accept audio,
with the exception of the VCRs (outputs 3 and 4) regardless of video group.
