LED wall that fits
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 19.2 m wall a Absen PL2.5 Plus V2 wall runs 30 x 14 (6000 x 2800 px, 3,276 kg, 67.2 kW).
| Panel | Pitch | Wall (cols x rows) | Size | Resolution | Weight | Power (max) |
|---|---|---|---|---|---|---|
| Absen KLCOB 0.78 | 0.78 mm | 25 x 20 = 500 | 15 x 6.8 m | 19200 x 8640 | 2,250 kg / 4,960 lb | 44.2 kW, 213 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 30 x 14 = 420 | 15 x 7 m | 6000 x 2800 | 3,276 kg / 7,222 lb | 67.2 kW, 323 A @ 208 V |
| Absen PL3.9 Plus V2 | 3.9 mm | 30 x 14 = 420 | 15 x 7 m | 3840 x 1792 | 3,276 kg / 7,222 lb | 58.8 kW, 283 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 C holds about 487 theater seats, 199 banquet seats at rounds of 10, or 137 classroom seats. Back row in theater is roughly 12.2 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
