TOA is a hit at Wimbledon Wimbledon’s famous grounds constantly evolve with the times, and this year the entire public address control network was redesigned. The TOA SX-1000 was crucial to the success of the installation.
The scope of the public
address and voice alarm for the club not only embraces the playing areas
and spectator facilities, but also reaches the car parks, queue lanes,
hospitality suites and
administrative offices.
The paging system feeds the large number of speakers connected to emergency zones to administer crowd control and voice evacuation, all the while ensuring that the police control microphone is given absolute priority. The software-driven SX-1000 is stationed in the Centre Court PA room and can be operated by its mainframe CPU or be hooked up to a PC to route simultaneous audio channels. These channels can be remotely monitored, and up to 64 priority levels can be assigned and up to 1000 operational events logged into memory. There are two vast equipment racks in the Broadcast Centre – five built by TOA two years ago, and another four later on by install company RG Jones. The racks are plugged with TOA VP series amplification, now totaling 47 x 240W units, 54 x 120W and 22 x 60W blocks – all fault monitored, using a total of 15 TOA FDU fault display units. These amplifiers are driving something in the region of 1,650 installed loudspeakers – and in addition, a further 100 or so auxiliary speakers are shipped in during the Wimbledon Championships Fortnight. Needless to say, the entire system is on battery back-up.
The new system has four paging microphones, which are routed to 16 zones (via the TOA SX-1000 matrix unit). Broadcast signal distribution is expedited via 20 media wall boxes, each having 16 outputs on their own discrete distribution amplifier. These are located around the Broadcast Centre and are available for any broadcaster (eg Channel 9 Australia used these feeds in addition to their own signals). The flexibility & possibilities available with the TOA system are only beginning to emerge as planning continues for Wimbledon 2005. |

In
time for this year's Championships a total control system that could be
operable from any of the PA control rooms was created, with remote
control also possible from courtside on Centre and No.1 Courts.
