Plan view

Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.

LED wall that fits

Under a 4.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 5 rows of 500 mm tile flown. Along the 84.3 m wall a Absen PL2.5 Plus V2 wall runs 134 x 5 (26800 x 1000 px, 5,226 kg, 107.2 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, Hall 3 holds about 15,605 theater seats, 6,384 banquet seats at rounds of 10, or 4,389 classroom seats. Back row in theater is roughly 77.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
