VENUE 103
Stadion Miejski Wroclaw © M. Przybyło / Aeroklub Wrocławski
- in which the building is covered by glass fiber mesh coated with a Teflon fiber net façade. As with the successful PGE Arena design, the company used EASE predictions for system optimisation, dividing the stadium stands into 14 separate zones, and assigning a zone each to the ancillary UEFA, VIP and Incentive boxes. ESS Audio has equipped the main bowl and stands with JBL PD Series loudspeakers, with rotated horns, specifying a total of 59 PD5200/95-WRX (90º x 50º) and 28 PD5200/43-WRX (40º x 30º) weatherised speakers, along with 56 PD5125-WRX weatherised subwoofers. These have mainly been mounted in clusters of five, comprising two PD5200/43-WRX, one PD5200/95-WRX and two PD5125-WRX weatherised speakers. A further three single PD5200/ 95’s fire onto the field, with two single clusters playing in front of the LED screens, aiming 90º down to the lower seating. Two additional clusters, comprising a pair of PD5200/95-WRX and PD5125-WRX, are set behind the LED screens for mid and high seat coverage. With the wind factor a major area for consideration, ESS prepared custom brackets for the PD enclosures, and as a further precaution, secured each PD speaker in the cluster with a steel line covered in polymer. Powering the rig are 47 Crown CTs 3000 amplifiers, fitted with PIP USP4 processor modules, and interfaced with a BSS Soundweb London DSP environment - allowing distribution over CobraNet, and for the system to be remotely controlled and monitored via Harman HiQnet System Architect. The stadium itself is divided into a number of dedicated zones, including 20 VIP boxes, 10 further Incentive Boxes (and UEFA boxes), a Business Club, a general esplanade / concourse, a fan shop, team zones (including indoor swimming pool) and media zone. In the UEFA, Incentive and VIP areas, 90 JBL ControlContractor 8128 ceiling speakers have been specified - powered by Crown CTs 600 amplification.
Amp racks are stationed in the four corners of the stadium (each containing a BSS Soundweb London BLU-80 DSP), while an additional BLU-800 processor is located in the Skybox. All five processors are equipped with input /output cards. Each rack also contains an automatic amp changeover, an Edimax switch along with several Moxa optical-Ethernet converters / switches, making the system fully redundant. This is easily interfaced with the stadium’s voice evacuation and fire alarm system via Soundweb London. Up in the Skybox is the technical control room where a Soundcraft GB4-16 console, a pair of JBL LSR2325P studio monitors, a rack with AKG DMS 700 wireless mic systems, various line devices (players and recorders) and Soundcraft redundant console power supply are located. From the Skybox music is broadcast and live announcements made, with an adjacent room for evacuation procedures, complete with fireman’s switch. The installation meets all required standards (including an STI of 0.5). ESS provided full training including use of the Skybox equipment, System Architect software and general problem solving. They will be able to log on and carry out regular health checks under strict safety rules. According to Karalow, this stadium project has been one of the most challenging the company has undertaken. Aside from Witold Karalow, the ESS Audio project team comprised System Designer, Wojciech Zielinski; Soundweb Programmer, Konrad Fengler; System Set-up, Wojciech Kopytek and Project Coordinator, Dariusz Kuta.
