LED wall that fits

Under a 8.8 m ceiling with 1.5 m trim and 0.3 m clearance you get 14 rows of 500 mm tile flown. Along the 36.9 m wall a Absen A2 Pro wall runs 59 x 14 (9912 x 2352 px, 8,260 kg, 152.8 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, Grand Ballroom- holds about 1,560 theater seats, 638 banquet seats at rounds of 10, or 438 classroom seats. Back row in theater is roughly 29.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
