Plan view

LED wall that fits

Under a 4 m ceiling with 1.5 m trim and 0.3 m clearance you get 4 rows of 500 mm tile flown. Along the 22.3 m wall a Absen A2 Pro wall runs 35 x 4 (5880 x 672 px, 1,400 kg, 25.9 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, Great Lakes East holds about 581 theater seats, 237 banquet seats at rounds of 10, or 163 classroom seats. Back row in theater is roughly 15.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
