Plan view

LED wall that fits

Under a 5.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 7 rows of 500 mm tile flown. Along the 43.9 m wall a Absen A2 Pro wall runs 70 x 7 (11760 x 1176 px, 4,900 kg, 90.7 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, Ambassador Ballroom holds about 2,135 theater seats, 873 banquet seats at rounds of 10, or 600 classroom seats. Back row in theater is roughly 36.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
