Plan view

LED wall that fits

Under a 5.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 7 rows of 500 mm tile flown. Along the 20.1 m wall a Absen A2 Pro wall runs 32 x 7 (5376 x 1176 px, 2,240 kg, 41.4 kW).

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.

Seating estimate

After a 12 x 7 m stage, Chicago Ballroom 9 holds about 371 theater seats, 152 banquet seats at rounds of 10, or 104 classroom seats. Back row in theater is roughly 13.1 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
