What fits in Grand Ballroom

With a 6.7 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 119 tiles wide by 9 high (1071 tiles, 59.5 x 4.5 m, 19992 x 1512 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 10,710 kg and draws up to 198.1 kW (953 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 6,901 theater, 2,823 banquet, or 1,941 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

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.

Planning notes

No rigging point data is published for this venue yet; plan on ground-supported LED or ask the venue for its rigging plot. 50 of the 77 rooms sit under 3.5 m, which rules out flown LED there and limits ground-stacked walls to about 6 rows of 500 mm tile.
