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 33.8 m wall a Absen A2 Pro wall runs 54 x 7 (9072 x 1176 px, 3,780 kg, 69.9 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, Grand ABC or FGH holds about 774 theater seats, 316 banquet seats at rounds of 10, or 217 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.
