Plan view

LED wall that fits

Under a 3.4 m ceiling with 1.5 m trim and 0.3 m clearance you get 3 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 11.6 m wall a Absen PL2.5 Plus V2 wall runs 18 x 3 (3600 x 600 px, 421 kg, 8.6 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, Federal B holds about 55 theater seats, 22 banquet seats at rounds of 10, or 15 classroom seats. Back row in theater is roughly 4.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
