Is there an overview of the FB4 interface structure available, menu tree maybe? How many color channels does the fb4 support ? Can the levels of the Yellow,cyan, and d.blue also be adjusted through the interface? It looks like the FB4 ilda through input only has RGB (3) support, is this 1:1 routed to the RGB output, or are there routing/summing options for the extra color channels ? Are the dmx possibilities of the FB4 identical to the FB3 ?
