Under a 8.8 m ceiling with 1.5 m trim and 0.3 m clearance you get 14 rows of 500 mm tile flown. Along the 31.7 m wall a Absen PL2.5 Plus V2 wall runs 50 x 14 (10000 x 2800 px, 5,460 kg, 112 kW).
| Panel | Pitch | Wall (cols x rows) | Size | Resolution | Weight | Power (max) |
|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 42 x 20 = 840 | 25.2 x 6.8 m | 32256 x 8640 | 3,780 kg / 8,333 lb | 74.3 kW, 357 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 50 x 14 = 700 | 25 x 7 m | 10000 x 2800 | 5,460 kg / 12,037 lb | 112 kW, 538 A @ 208 V |
| Absen PL3.9 Plus V2 | 3.9 mm | 50 x 14 = 700 | 25 x 7 m | 6400 x 1792 | 5,460 kg / 12,037 lb | 98 kW, 471 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.
Seating estimate
After a 12 x 7 m stage, Grand Horizon B/C holds about 1,165 theater seats, 476 banquet seats at rounds of 10, or 327 classroom seats. Back row in theater is roughly 24.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
