Plan view

LED wall that fits

Under a 4.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 4 rows of 500 mm tile flown. Along the 42.3 m wall a Absen PL2.5 Plus V2 wall runs 67 x 4 (13400 x 800 px, 2,090 kg, 42.9 kW).

Absen PL2.5 Plus V2	2.5 mm	67 x 4 = 268	33.5 x 2 m	13400 x 800	2,090 kg / 4,608 lb	42.9 kW, 206 A @ 208 V

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, Key Ballroom Foyer holds about 3,789 theater seats, 1,550 banquet seats at rounds of 10, or 1,065 classroom seats. Back row in theater is roughly 35.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
