What fits in Grand Ballroom
With a 4.3 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 45 tiles wide by 4 high (180 tiles, 22.5 x 2 m, 7560 x 672 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 1,800 kg and draws up to 33.3 kW (160 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 1,407 theater, 575 banquet, or 395 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

|---|---|---|---|---|---|---|

| Absen A2 Pro | 2.97 mm | 45 x 4 = 180 | 22.5 x 2 m | 7560 x 672 | 1,800 kg / 3,968 lb | 33.3 kW, 160 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.
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. 8 of the 18 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.
Data source
Published dimensions. Dimensions from the venue's published meeting-space specifications (source). Rooms drawn as boxes use published length x width; square rooms were derived from published area only, so treat their shape as approximate. Venue managers: send a floor plan to upgrade your listing to production-ready.
