Extron electronic MVX 88 Series ユーザーズマニュアル

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.

Figure 3-43 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.
