4–20 • Preliminary Cabling and Video Installation Synergy Q/MD Engineering Manual (v9.1 MD)
Input Worksheet
Complete the following worksheet for all of your video inputs, including primary sources, keys, and
fills. To avoid marking up the
Engineering Manual , you can also use the worksheet provided in
Appendix C, “ Installation Worksheets ” to make extra copies.
Following are basic input recommendations:
• Connect your analog reference to the reference input (as outlined earlier in this chapter).
• Connect your primary video sources to inputs C01 , C02 , C03 (etc.), and then continue
forward in sequence.
On the control panel, by default, input C01 is mapped to pushbutton 2 , input C02 is
mapped to pushbutton 3 , etc. This association will minimize subsequent re-mapping of
your inputs, and make it very easy for you to locate inputs on the panel during the initial
cabling procedure.
• Connect your Key signals (alphas) to your highest available input number, and then
continue backwards in sequence. The starting point will be determined by the number of
input boards installed in your system. For example:
~ If your system has only the 16 standard inputs, start alphas at input C16 , then C15 ,
C14 , etc.
~ If additional inputs have been installed, start alphas at input D10 or D16 , depending
on your configuration, and continue backwards from there. (e.g., D16 , then D15 ,
D14 , etc.)
In each case, use the your highest available input number. This association will allow
you to view each alpha during preliminary cabling, and will also assist in the subsequent
alpha-to-video re-mapping procedure.
Using the above recommendations, complete the following input worksheet. The majority of this data
will be used in the section “
BNC Configuration ” on page 7-2 to complete the configuration of each
input.
For each input (moving from left to right in the worksheet columns):
• Fill in the actual source name. For example:
~ VTR 1
• Fill in the input name (up to 8 characters), as you would like to see it displayed
throughout the menu system (and on the
Preview Overlay ). For example:
~ VTR Blue
• Fill in the type of input. Choose between:
~ Off
~ VTR
~ Alpha
~ Router
Important
Until you connect the reference input, your switcher will not output
video.
