Worksheet Example 3: Test Configuration
The A/V system in our ctional organization needs to be ne tuned on a regular basis.
Figure 26 shows a typical test conguration, 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.
