BiaŁystok City Stadium, located in the largest city in Northeastern Poland and the capital of the Podlaskie Voivodeship, has undergone major redevelopment, with a new 360-degree grandstand hosting up to 22,400 who are served by a new sound reinforcement system with Community Professional loudspeakers.
The system was designed by Tommex Żebrowscy Sp. J., with installation completed by Zeto S.A. in time for the opening of the modernized venue earlier this year, under the direction of project manager Zbigniew Kaczmarczyk.
The main loudspeaker set comprises 48 Community R2-474s and three R2-52s. The combination provides the dispersion patterns required for complete coverage of the stadium’s 360-degree grandstand. In addition, 38 R.25-94s and 41 R.5-99s deliver audio for the stadium’s internal promenades and public areas around the building.
The main system components are housed in the commentary room and linked to four separate amplifier rooms. The audio signal is transmitted over the stadium’s network using the Dante protocol and is triple redundant, with two fiber rings and a turbo function ring. It’s the largest system based on Dante operating in any stadium in Poland.
The system uses a Dynacord CMS 2200-3 audio mixer, 16 x 16 DSP equipped digital control matrix and a DPM 8016 digital matrix manager. The audio matrix is 32 × 32 and handled by Dynacord’s P 64 digital audio matrix units. By using the IRIS-Net network, each element of the system is continuously monitored and all operations are controlled via a Dell all-in-one touch-screen PC.
Twenty Dynacord DSA 8410 4-channel amplifiers provide a total of 80 kW to power the Community loudspeakers. A DPC 8015 microphone, located on the Events Security Commander desk, has full priority over other audio signals, enabling the effective communication of voice messages in the event of non-standard events.
“Visitors to BiaŁystok City Stadium will not only enjoy their sports with great audio quality, but they can also be assured that their safety is our primary concern with reliability being a fundamental consideration in the design and every component of the system,” says Marcin Zimny of Tommex Żebrowscy.
