What fits in Halls A-D
With a 9.1 m ceiling, a flown wall of Absen PL2.5 Plus V2 (2.5 mm) runs 234 tiles wide by 14 high (3276 tiles, 117 x 7 m, 46800 x 2800 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 25,553 kg and draws up to 524.2 kW (2520 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 20,620 theater, 8,435 banquet, or 5,799 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) |
|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 195 x 21 = 4095 | 117 x 7.1 m | 149760 x 9072 | 18,428 kg / 40,625 lb | 362.4 kW, 1742 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 234 x 14 = 3276 | 117 x 7 m | 46800 x 2800 | 25,553 kg / 56,334 lb | 524.2 kW, 2520 A @ 208 V |
| Absen PL3.9 Plus V2 | 3.9 mm | 234 x 14 = 3276 | 117 x 7 m | 29952 x 1792 | 25,553 kg / 56,334 lb | 458.6 kW, 2205 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. 2 of the 10 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.
