Plan view

LED wall that fits

Under a 7.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 11 rows of 500 mm tile flown. Along the 30.1 m wall a Absen A2 Pro wall runs 48 x 11 (8064 x 1848 px, 5,280 kg, 97.7 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, Ballroom A holds about 1,030 theater seats, 421 banquet seats at rounds of 10, or 289 classroom seats. Back row in theater is roughly 23.1 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
