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 9 m ceiling with 1.5 m trim and 0.3 m clearance you get 14 rows of 500 mm tile flown. Along the 53.7 m wall a Absen PL2.5 Plus V2 wall runs 85 x 14 (17000 x 2800 px, 9,282 kg, 190.4 kW).

Absen KLCOB 0.78	0.78 mm	71 x 21 = 1491	42.6 x 7.1 m	54528 x 9072	6,710 kg / 14,792 lb	131.9 kW, 634 A @ 208 V
Absen PL2.5 Plus V2	2.5 mm	85 x 14 = 1190	42.5 x 7 m	17000 x 2800	9,282 kg / 20,463 lb	190.4 kW, 915 A @ 208 V
Absen PL3.9 Plus V2	3.9 mm	85 x 14 = 1190	42.5 x 7 m	10880 x 1792	9,282 kg / 20,463 lb	166.6 kW, 801 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 Ballroom holds about 6,221 theater seats, 2,545 banquet seats at rounds of 10, or 1,749 classroom seats. Back row in theater is roughly 46.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
