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 25.6 m wall a Absen A2 Pro wall runs 40 x 6 (6720 x 1008 px, 2,400 kg, 44.4 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, Regency AB or C or D or EF holds about 678 theater seats, 277 banquet seats at rounds of 10, or 190 classroom seats. Back row in theater is roughly 18.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
