Worksheets

Rather than trying to remember the configuration for each preset, use worksheets
to record this information. Make copies of the blank worksheet on page 3-17 and
use one for each preset configuration. The forms accommodate all of the MAV
models. Cross off all unused or inactive inputs and outputs. Use different colors
for video and audio.

Worksheet example 1: System equipment

Figure 3-19 shows a worksheet for a MAV 1616 in a fictional organization with the
system hardware annotated. Inputs 10 and 11 and output 7 have no connections in
this organization, so they have been crossed out on the worksheet.
Inputs include video cameras, audio tape and CD players, laser disc players, VCRs,
and a VTG 200. Output devices include monitors, front and rear projectors, a
stereo, and several VCRs.
Note that VCRs 1, 2, 3, and 4 are connected to inputs 13 – 16 and also to outputs
13 – 16. This arrangement is convenient for video editing applications. Connecting
the VCR inputs and outputs to the same inputs and outputs on the switcher is not a
requirement. They can be separated and spread around in any configuration
The Extron VTG 200 video test generator connected to input 12 enables a video test
pattern to be sent to one, several, or all output devices for problem isolation or
adjustment purposes. An audio test tape or CD could be used in a similar manner
to check out the audio components.
