Poland’s Śląski Stadium (Silesian Stadium) in Chorzów has undergone a complete rebuild.The original stadium, opened in 1956,has played host to concerts by the likes of U2, AC/DC, Iron Maiden and The Rolling Stones.

An initial system design was put together by Dr. Piotr Kozłowski of Wrocław-based Acoustic Laboratory Pracownia Akustyczna, who subsequently approached Polish distributor Tommex to begin the process of equipment selection. Local company NOMA2 was brought in to carry out the detailed installation work under the guidance of its manager, Janusz Konopka.Tommex chose Community Loudspeakers, having already proven their acoustic performance and all-weather reliability in numerous Polish stadia. The system designed by Tommex is based around Dynacord electronics and Community loudspeakers. The main system for the spectator stands is divided into eight zones and utilises one hundred nineteen Community R2-52Z three-way loudspeakers, supplemented by forty R6-BASSHORN.

The raked seating of Śląski Stadium creates theatre-style balcony overhangs and the under balcony seating and walkway areas are covered by sixty-one Community W2-2W8 loudspeakers. The playing field is covered by four powerful three-way R2-694Z loudspeakers.System management is located in the commentator room in the eastern stand. This is where a Yamaha CL1 digital mixer, Dynacord P64 matrix and Dante to MADI converters are located, MADI being the format for transmission of audio between the Yamaha CL1 and OB vans when providing signals for television or radio.

Using the Dante protocol, the audio signal is distributed by two redundant optical fibre cables with a third optical fibre used for communication of the IRIS-Net network. System amplification includes forty two-channel Dynacord DSA 8209 amplifiers and forty-seven four-channel DSA 8410 amplifiers.A PC provides full control and system management via the IRIS-Net network. The system includes both wired and wireless microphone systems, with feedback eliminators. Zone microphones are additionally equipped with automatic regulators that adjust the signal level according to the background noise level and a Dynacord Promatrix microphone zone panel allows PA messages to be made by the stadium’s safety and security staff. CD, MP3, USB and SSD players are also provided.In addition to the main stadium systems, eighty Community loudspeakers are installed on pillars that surround the stadium. Forty R.25-94Z loudspeakers are directed to the gallery, which surrounds the walls of the stadium and forty ENT-FR high performance column line source loudspeakers cover the area between the stadium and the venue’s perimeter fence and entrance gates. Indoor rooms and public areas of the stadium building are covered by one-hundred eight Community I/O8 and eighty-eight DS8 wall-mounted loudspeakers.All of the sound systems at Śląski Stadium are fully integrated with the audio warning system, which, if necessary, can take full priority and use the sound system for more efficient crowd control and evacuation of fans in the event of an emergency.Marcin Zimny, commercial director of Tommex, said: “We are very pleased with the sound system at Śląski Stadium. With built-in reliability, it provides high intelligibility speech, great music quality and consistent coverage for this prominent international venue. It’s also a system of which we can be proud, being the largest sound system installed in any sports facility in Poland. It was a pleasure to work with Dr. Piotr Kozlowski and Pacownika Akustyczna and the installation company NOMA2, all high profile specialists in their fields.”
