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 9 m ceiling with 1.5 m trim and 0.3 m clearance you get 14 rows of 500 mm tile flown. Along the 41.7 m wall a Absen PL2.5 Plus V2 wall runs 66 x 14 (13200 x 2800 px, 7,207 kg, 147.8 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, Grand Ballroom B1 + B2 holds about 3,677 theater seats, 1,504 banquet seats at rounds of 10, or 1,034 classroom seats. Back row in theater is roughly 34.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
