Plan view

LED wall that fits

Under a 7.3 m ceiling with 1.5 m trim and 0.3 m clearance you get 11 rows of 500 mm tile flown. Along the 35.7 m wall a Absen A2 Pro wall runs 57 x 11 (9576 x 1848 px, 6,270 kg, 116 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/B holds about 2,209 theater seats, 903 banquet seats at rounds of 10, or 621 classroom seats. Back row in theater is roughly 28.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
