Crestron CNX-PVID8x4 Professional Video Distribution Switch
Operations Guide - DOC. 8166A Professional Video Distribution Switch: CNX-PVID8x4 • 19
Signal Distribution to More than Eight Rooms
Each CNX-PVID8x4 is capable of distributing video to eight rooms, maximum. It is
possible to expand distribution to more rooms, if additional CNX-PVID8x4s are
introduced to the system. Crestron recommends a maximum of four CNX-PVID8x4s
per system. Therefore, video can be distributed to a maximum of 32 rooms. Each
input to the unit has two RCA jacks connected in parallel (per level). Use one of the
jacks for loop-through, as shown in the illustration after this paragraph.
NOTE: The last unit in the loop-through connection must have terminators
installed.
