Conference Hall C1 at Metropolitan Expo

Conference Hall C1 is 22.6 x 22.6 m (74 x 74 ft), 511 m² (5,498 sq ft), with a 6 m (20 ft) ceiling.

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 m ceiling with 1.5 m trim and 0.3 m clearance you get 8 rows of 500 mm tile flown. Along the 22.6 m wall a Absen A2 Pro wall runs 36 x 8 (6048 x 1344 px, 2,880 kg, 53.3 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, Conference Hall C1 holds about 948 theater seats, 388 banquet seats at rounds of 10, or 266 classroom seats. Back row in theater is roughly 15.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
