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 50.6 m wall a Absen A2 Pro wall runs 80 x 7 (13440 x 1176 px, 5,600 kg, 103.6 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, Allegheny Grand Ballroom holds about 2,927 theater seats, 1,197 banquet seats at rounds of 10, or 823 classroom seats. Back row in theater is roughly 43.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
