No thats not right ! not so many CAT7
Matrix "brand" is not gefen it's ATLONA
Ex 1.
If you have the matrix ( ATLONA) in let's say livingroom were videomaster and sources is
you need hdmi conection from each source to matrix and then 2 Cat 6/7 to each linkroom from matrix, depending on matrix model
you can have 3 or 7 linkroom (1 output connected to videomaster (HDMI)) and 4 or 8 sources and Puc cable to videomaster
Ex 2.
If you have technical room were the source and matrix placed you have HDMI between sources and matrix and CAT 7 X2 to each
linkroom and videomaster and also Puc cable from videomaster to matrix
In all linkroom you need CAT7 converter to HDMI (in Ex 2. also to videomaster if to long for HDMI)
