Plan view

LED wall that fits

Under a 4.6 m ceiling with 1.5 m trim and 0.3 m clearance you get 5 rows of 500 mm tile flown. Along the 17.7 m wall a Absen A2 Pro wall runs 28 x 5 (4704 x 840 px, 1,400 kg, 25.9 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, Sapphire Room holds about 147 theater seats, 60 banquet seats at rounds of 10, or 41 classroom seats. Back row in theater is roughly 10.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
