Build the show before the kit arrives
Lay the whole rig out on screen weeks before a single box is racked: routers, patchbays, switchers, converters, projectors, laptops. None of it has to be plugged in yet.
Pre-build Constellations
Set an ATEM up while it is still in the flight case: the auxes, the multiviewer, every label. When the switcher is racked and on the network, one press writes the lot to it.
Fit the cards, the I/O follows
A Barco Event Master or an Analog Way Aquilon arrives as an empty chassis and its page is a drawing of the real rear panel. Drop cards into the bays and the inputs and outputs appear as they would on the unit. Put a card in a slot that will not take it and the frame says no, exactly as it would in the rack. Save the build and drop it onto the next show.
Real models, not rectangles
Add a Barco PDS-4K or a Roland V-160HD and the right sockets are already on it, down to which inputs are HDMI and which are SDI. Every port list was typed in off the manufacturer’s own spec sheet, so what you draw is what you will find behind the rack.
