Gdynia, Poland â€“ August 2011â€¦ Gdynia Municipal Football stadium is the home to Polandâ€™s Arka Gdynia football club. With a seating capacity of roughly 15,139 spectators, the new facility recently received a large, networked audio-driven sound reinforcement system. To ensure even coverage across the stadiumâ€™s multiple zones, loudspeakers from the catalog of Valencia, Spain-based D.A.S. Audio were placed into service.
Sopot, Poland-based Mega Musicâ€™s audio-visual installation division was contracted to handle the Gdynia Municipal Football stadiumâ€™s new sound system. Mega Musicâ€™s Piotr NowiÅ„ski managed the project and discussed the challenges of the job, which involved the deployment of D.A.S. Audioâ€™s DR-12 2-way, full-range loudspeakers, the BiDriver Plus, which is a 2-way, mid-high unit designed for long throw applications, and the companyâ€™s CL-6T ceiling speakers.
â€œThe D.A.S. DR-12â€™s were our loudspeakers of choice to cover the audience seating areas on this project,â€? explained NowiÅ„ski, â€œas they provide perfect speech intelligibility. Further, the uniform dispersion characteristics of DR-12â€™s enabled us to provide even coverage of the audience seating areas with a minimum number of boxes. The high sensitivity and flat frequency response of the loudspeakers enabled us to achieve a high SPL level with no compromise to sound quality. For the field, the BiDrivers Plus were the right tool, as they provide extreme throw distance while maintaining high sound quality.â€?
The stadiumâ€™s grandstand areas were divided into 44 zones and for these areas, a total of 84 D.A.S. DR-12 enclosures were placed into service. With its rugged Polypropylene enclosure, the DR-12â€™s used for this project were custom built by D.A.S. to the IP54 rating for outdoor use.
The football field was divided into 4 zones and, to cover this area, 8 D.A.S. Audio BiDriver Plus loudspeaker systems were placed into service. The Bi-Driver Plus incorporates a co-axial speaker built into a special horn unit and is particularly well suited to applications where a high level of speech intelligibility is required. â€œWith its long throw characteristics, this was the perfect choice for the field areas,â€? noted NowiÅ„ski.â€?
Coverage for the stadiumâ€™s corridors and select outside areas were addressed by forming another 30 zones. For these areas, D.A.S. Audio CL-6T ceiling speakers were deployed. Equipped with a multi-tap line transformer for distributed audio systems, the CL-6T is a 2-way passive full range ceiling loudspeaker incorporating a 6.5â€? cone low frequency transducer and a ferrofluid cooled 1" soft dome high frequency unit with integral diffraction ring.
â€œThe distributed main audio system that we designed for this project is managed by a Symetrix SymNet DSP processor, networked together via a 4-node CobraNet setup,â€? said NowiÅ„ski. â€œThe main system is fed by Ashly NE8250PE multichannel, networked amplifiers. Both the SymNet and Ashly amps are controlled via a PC application. Audio mixing is handled via a Crest Audio XR20 analog mixing desk located in the control room. The corridor areas are run by a Bosh Presidio network controller and Bosh PRS amplifiers.â€?
With the new sound system in service, NowiÅ„ski reports that stadium management, the players, and the fans are all noticing a dramatic improvement in the sound quality. â€œWe getting perfect, uniform sound coverage throughout the audience stands and across the field,â€? NowiÅ„ski proudly notes. â€œThe sound pressure level (SPL-A) ranges between 111 â€“ 113 dB with no significant drops to be found anywhere. Equally important, the sound quality is excellent. Weâ€™re experiencing very good frequency range and, remember, there were no subwoofers used on this project. The folks at D.A.S. Audio were a tremendous help with this projectâ€”providing quality support in timely fashionâ€” and, together, I believe weâ€™ve created a really impressive system that will serve the areaâ€™s football fans for years to come.â€?
