Plan view

LED wall that fits

Under a 7.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 11 rows of 500 mm tile flown. Along the 29.9 m wall a Absen A2 Pro wall runs 47 x 11 (7896 x 1848 px, 5,170 kg, 95.6 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, Ballroom C holds about 1,428 theater seats, 584 banquet seats at rounds of 10, or 401 classroom seats. Back row in theater is roughly 22.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
