Keep in mind that for the NV8500 hybrid routers, some video and audio ports in the list do not
actually exist. Takes to or from these ports are “no-ops.” For example, the 9th port of any disem-
bedder card is vacant. The 16 audio ports that would be associated with it do not exist.
Diagonal Takes
A diagonal take connects inputs M to outputs N, in ascending order, given an input starting
point that you specify:
A reverse diagonal take connects inputs M to outputs N, in descending order, given an input
starting point that you specify:
If the resulting input would fall out of the absolute range of the crosspoint matrix, an individual
take is not performed. MRC will perform as many takes, in the range you specify, as it can.
You can perform diagonal and reverse diagonal takes in the ‘Current’ tab or in a ‘Salvo’ tab.
How to Perform a Diagonal Take
1 Go to the ‘Crosspoints’ page. From the Control Cards table, at the bottom of the page, select
a control card.
2 Select a level from the ‘Level’ drop-down menu. The crosspoint matrix for that level appears.
3 (Optional) Select contiguous outputs in the displayed table.

Input starting point P = 30;
Output starting point Q = 3;
As output N varies from 3–10,
input M = P + (N–Q)
