We all remember the phrase, “It's the economy, stupid,” made famous by political strategist James Carville, who hung it on a sign in Bill Clinton's Little Rock campaign office.

During the engineering charette for KÀ, it was determined that the Ethernet network was going to be the crucial design element of this system. The Cirque du Soleil, Auerbach, and Strand team members, led by Jeanette Farmer, decided that to fulfill the “maximum flexibility” mission statement, every control device needed to be able to communicate across the Strand ShowNet network. This meant that even a simple custodial key switch would need the ability to control output device properties across the network.

This was no small task, but all of the hard work by the team members paid off during the load in and production for the show. Since any input device (console, touch screen, key switch, button station) had the potential to be configured to access any output device, total system flexibility was achieved. Cirque du Soleil now had the ability (in software) to re-configure their system based on the almost daily changing needs of the KĂ€ production. The following list of equipment represents the major elements of the network (see main gear list for specific manufacturers).

9 lighting consoles
4 wireless personal digital assistants
