Plan view

LED wall that fits

Under a 4.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 5 rows of 500 mm tile flown. Along the 33.8 m wall a Absen PL2.5 Plus V2 wall runs 54 x 5 (10800 x 1000 px, 2,106 kg, 43.2 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 1,097 theater seats, 449 banquet seats at rounds of 10, or 308 classroom seats. Back row in theater is roughly 26.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
