LED wall that fits

Under a 5.2 m ceiling with 1.5 m trim and 0.3 m clearance you get 6 rows of 500 mm tile flown. Along the 26.8 m wall a Absen A2 Pro wall runs 42 x 6 (7056 x 1008 px, 2,520 kg, 46.6 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, Junior Ballroom 111B holds about 682 theater seats, 279 banquet seats at rounds of 10, or 192 classroom seats. Back row in theater is roughly 19.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
