Published dimensions

Plan view

Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.

LED wall that fits

Under a 3.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 2 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 20 m wall a Absen PL2.5 Plus V2 wall runs 32 x 2 (6400 x 400 px, 499 kg, 10.2 kW).

Panel	Pitch	Wall (cols x rows)	Size	Resolution	Weight	Power (max)
Absen KLCOB 0.78	0.78 mm	26 x 3 = 78	15.6 x 1 m	19968 x 1296	351 kg / 774 lb	6.9 kW, 33 A @ 208 V
Absen PL2.5 Plus V2	2.5 mm	32 x 2 = 64	16 x 1 m	6400 x 400	499 kg / 1,101 lb	10.2 kW, 49 A @ 208 V
Absen PL3.9 Plus V2	3.9 mm	32 x 2 = 64	16 x 1 m	4096 x 256	499 kg / 1,101 lb	9 kW, 43 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, A4 holds about 702 theater seats, 287 banquet seats at rounds of 10, or 197 classroom seats. Back row in theater is roughly 13 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
