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 6.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 9 rows of 500 mm tile flown. Along the 16.6 m wall a Absen A2 Pro wall runs 26 x 9 (4368 x 1512 px, 2,340 kg, 43.3 kW).

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, Ribeira I & II holds about 425 theater seats, 174 banquet seats at rounds of 10, or 119 classroom seats. Back row in theater is roughly 9.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
