The Adelaide Convention Centre is set to open mid-2017, and its choice of PA for the new 3500-seat Plenary Hall has been Meyer Sound’s Leopard compact line array system. The space will be covered by a left/right hang of 10 Leopard elements per side, with three 900-LFC subs per side rigged in cardioid pattern.

The Plenary is a bit like a transformer. Not only can it split in half, but the hall can also add two banks of 300 pax each raked seating on circular revolves the rear of the auditorium, which rotate independently and bring in their own walls to form separate break-out spaces. If that isn’t enough, the main auditorium’s 2900 seats can retract into the ceiling, forming a banquet space or independent meeting rooms underneath.

So how does all this re-jigging affect the PA? That’s been tackled rather intelligently. The Leopard system will be flown and installed, and different configuration settings will be loaded remotely via Meyer Sound’s Compass software or Compass Go iPad app. This avoids unsightly ground stacks and reduces ongoing labour costs and equipment wear and tear.

“We’ve designed the system so the ACC don’t have to constantly fly the system in and out,” said Meyer Sound Australia’s Chris D’Bais. “We will run individual signal and power feeds to every box, and through our Galileo Galaxy processing, the ACC will be able remotely load whichever preset suits the room configuration — if they’re only using the front half of the room, for example, they can turn the top of the array off so there’s no extra SPL bouncing around the empty space. Each independent space will have its own independent processor, so separate users can control their sub-systems. Then in full mode, the main processor collates all the data and controls the combined system.”

Front fill, and under balcony fill in the Plenary will be covered by Meyer Sound UPM-1P and UPJunior compact wide coverage speakers respectively. In the near future, the ACC will also have the option to distribute signal and control via AVB with Meyer’s new Galileo Galaxy processors. Rounding out the full system in the Plenary will be 16 units of Meyer’s low profile MJF-208 self-powered stage monitors; low-profile dual 8-inch compression driver wedges weighing in at just 21kgs.
