Plan view

LED wall that fits

Under a 9.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 14 rows of 500 mm tile flown. Along the 17.7 m wall a Absen A2 Pro wall runs 28 x 14 (4704 x 2352 px, 3,920 kg, 72.5 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, Astor Ballroom I holds about 257 theater seats, 105 banquet seats at rounds of 10, or 72 classroom seats. Back row in theater is roughly 10.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
