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 2.4 m ceiling with 1.5 m trim and 0.3 m clearance you get 1 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 5.8 m wall a Absen A2 Pro wall runs 9 x 1 (1512 x 168 px, 90 kg, 1.7 kW).

Panel	Pitch	Wall (cols x rows)	Size	Resolution	Weight	Power (max)
9thPanel DW1.9 S Pro	1.875 mm	7 x 1 = 7	4.2 x 0.3 m	2240 x 180	34 kg / 74 lb	1.8 kW, 9 A @ 208 V
Absen A2 Pro	2.97 mm	9 x 1 = 9	4.5 x 0.5 m	1512 x 168	90 kg / 198 lb	1.7 kW, 8 A @ 208 V
Absen A3 Pro	3.9 mm	9 x 1 = 9	4.5 x 0.5 m	1152 x 128	86 kg / 188 lb	1.4 kW, 7 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, Pre-Function C holds about 0 theater seats, 0 banquet seats at rounds of 10, or 0 classroom seats. Back row in theater is roughly -1.2 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
