Nyíregyháza is situated near the border with Ukraine, Slovakia and Romania and is the seventh largest city in Hungary. It is also one of the most prosperous, being both an educational centre and a popular tourist destination.
The 6,000 capacity Nyíregyháza City Stadium has been a venue for major international events and is also home to the local soccer team, Nyíregyháza Spartacus, which plays in Hungary's top professional league, the NB1. In a project that commenced in August 2009, the 50 year old stadium has undergone much reconstruction and a complete refurbishment to bring it up to modern international standards. The works have included the renewal of the grandstands, athletic field and building interiors, all being completed for the 17th European Veteran Athletics Championship (EVAC) which the venue will host in July 2010.
Interton Electroacoustics were appointed to design and install the PA, as Dr. Géza Balogh, Interton's electro-acoustic designer, explained, "The brief was to provide loud and clear PA for the soccer field, the surrounding athletic field and the grandstands. The specification was for the system to provide 103dB +/-4dB SPL throughout these specified areas.
"We chose the Community R2 system. Having the experience of using this high output, all-weather system very successfully in many installations it was an obvious choice for this stadium. They are reliable and robust, with well controlled dispersion and excellent intelligibility; really unequalled for this kind of application. The main system incorporates six R2-94Z, mounted on a lighting pole."
To achieve the specified coverage and SPL from a single location Dr. Géza Balogh meticulously calculated the angles for each individual speaker and Interton's install department also designed custom frames to position the R2's as required. The system power is provided by QSC RMX4050HD amplifiers and DSP is provided by a TOA M-9000.
"A few local people doubted we would meet the required level when they saw the size of the system within the venue", said Interton senior engineer, Zoltán Horváth, "But their look of surprise was very pleasing to see as we comfortably exceeded the specification."
