What fits in O'Hare Int'l Ballroom

With a 3.7 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 135 tiles wide by 3 high (405 tiles, 67.5 x 1.5 m, 22680 x 504 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 4,050 kg and draws up to 74.9 kW (360 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 4,614 theater, 1,887 banquet, or 1,297 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.

Planning notes

No rigging point data is published for this venue yet; plan on ground-supported LED or ask the venue for its rigging plot. 30 of the 53 rooms sit under 3.5 m, which rules out flown LED there and limits ground-stacked walls to about 6 rows of 500 mm tile. O'Hare Int'l Ballroom is a long room (3.3:1), so put the wall on the short end and expect the back row to be 84.4 m out; a 2.97 mm pitch holds up at that distance.
