Worksheet Example 3: Test Configuration

The A/V system in our fictional organization needs to be fine tuned on a regular basis. Figure 26 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 two output devices that accept audio; the VCR (output 6) receives no audio in this configuration. Note that the audio is redirected from the low resolution group to the computer group.
