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 3-31 and
use one for each preset configuration. Cross out all unused or inactive inputs and
outputs. If applicable, use different colors for video and audio.
Worksheet example 1: System equipment
Figure 3-44 shows a worksheet for a MAV 88 AV in a fictional organization with the
system hardware annotated. Input 6 has no connection in this organization, so it
has been crossed out on the worksheet.
Inputs include PCs (scan converted to composite video by an Extron USP 405 signal
processor), an audio CD player, cameras, and an Extron VTG 300. Output devices
include monitors, front and rear projectors, a stereo, and a VCR for recording
presentations.
The VTG 300 video test generator connected to input 8 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.
