What fits in Grand Ballroom
With a 4 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 62 tiles wide by 4 high (248 tiles, 31 x 2 m, 10416 x 672 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 2,480 kg and draws up to 45.9 kW (221 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 634 theater, 259 banquet, or 178 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.
| Panel | Pitch | Wall (cols x rows) | Size | Resolution | Weight | Power (max) |
|---|---|---|---|---|---|---|
| 9thPanel DW1.9 S Pro | 1.875 mm | 51 x 6 = 306 | 30.6 x 2 m | 16320 x 1080 | 1,469 kg / 3,238 lb | 77.7 kW, 374 A @ 208 V |
| Absen A2 Pro | 2.97 mm | 62 x 4 = 248 | 31 x 2 m | 10416 x 672 | 2,480 kg / 5,467 lb | 45.9 kW, 221 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. 18 of the 29 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. Grand Ballroom is a long room (4.1:1), so put the wall on the short end and expect the back row to be 38.9 m out; a 2.97 mm pitch holds up at that distance.
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.
