The Stadium boasts yet another stadium audio system, designed and implemented by The PA People, using the proven formula of JBL Application Engineered loudspeakers with weatherised treatment for external use (WRX) as well as JBL Control Contractor 29AV and 25AV products. All speakers are driven by Crown CTS amplifiers fitted with the latest Crown DSP card - Crown IQ PIPUSP4/CN. Overlay processing and control is via BSS London BLU systems.
Loudspeakers for the stands consist of six clusters of spaced elements mounted close to the leading edge of the roof and a quantity of fill-speakers to cover areas shadowed from the main clusters. The clusters comprise of one JBL AM5212 to cover the grandstand upper seating and one JBL AM4315 to cover the grandstand lower seating.
Both loudspeakers are oriented horizontally; careful selection of the horn pattern and orientation allows the grandstand upper seating to be serviced by a single enclosure while maintaining SPL variation of within the target +/- 3dB. Servicing the grandstand upper seating with a single enclosure has the added advantage of virtually eliminating interference effects such as comb filtering which occurs when arraying loudspeakers to cover a common zone.
Open arena viewing areas, are covered by using the 'long throw' JBL PD5212WRX. A total of 72 JBL Control25AV speakers and 24 JBL Control29AV speakers are deployed for coverage to the grandstand in-fill areas.
