Plenary 1 or 3 at Melbourne Convention and Exhibition Centre (MCEC)

Plenary 1 or 3 is 38.5 x 38.5 m (126 x 126 ft), 1,482 m² (15,955 sq ft), with a 16.9 m (55 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 16.9 m ceiling with 1.5 m trim and 0.3 m clearance you get 30 rows of 500 mm tile flown. Along the 38.5 m wall a Absen A2 Pro wall runs 61 x 30 (10248 x 5040 px, 18,300 kg, 338.6 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, Plenary 1 or 3 holds about 3,107 theater seats, 1,271 banquet seats at rounds of 10, or 873 classroom seats. Back row in theater is roughly 31.5 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
