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 35 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 18 shows a worksheet for an MVX 88 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, 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.
