Published dimensions

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 5.2 m ceiling with 1.5 m trim and 0.3 m clearance you get 6 rows of 500 mm tile flown. Along the 38.8 m wall a Absen PL2.5 Plus V2 wall runs 62 x 6 (12400 x 1200 px, 2,902 kg, 59.5 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 CDEF holds about 3,158 theater seats, 1,292 banquet seats at rounds of 10, or 888 classroom seats. Back row in theater is roughly 31.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
