Plan view

LED wall that fits

Under a 5.8 m ceiling with 1.5 m trim and 0.3 m clearance you get 7 rows of 500 mm tile flown. Along the 53.9 m wall a Absen A2 Pro wall runs 86 x 7 (14448 x 1176 px, 6,020 kg, 111.4 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, Combined Northern Lights Ballroom A & B holds about 2,843 theater seats, 1,163 banquet seats at rounds of 10, or 799 classroom seats. Back row in theater is roughly 46.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
