Plan view

LED wall that fits

Under a 4.9 m ceiling with 1.5 m trim and 0.3 m clearance you get 6 rows of 500 mm tile flown. Along the 47.5 m wall a Absen A2 Pro wall runs 76 x 6 (12768 x 1008 px, 4,560 kg, 84.4 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, Potomac Ballroom holds about 3,740 theater seats, 1,529 banquet seats at rounds of 10, or 1,051 classroom seats. Back row in theater is roughly 40.5 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
