Plan view

LED wall that fits

Under a 4.3 m ceiling with 1.5 m trim and 0.3 m clearance you get 4 rows of 500 mm tile flown. Along the 28.7 m wall a Absen PL2.5 Plus V2 wall runs 45 x 4 (9000 x 800 px, 1,404 kg, 28.8 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, Pre-Assembly holds about 514 theater seats, 210 banquet seats at rounds of 10, or 144 classroom seats. Back row in theater is roughly 21.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
