Leading-edge audio system for Bialystok’s world-class stadium

Białystok City Stadium is located in the largest city in Northeastern Poland and the capital of the Podlaskie Voivodeship. The stadium has undergone major redevelopment and substantial new construction and now meets the highest world standards for modern sports facilities. The new 360 degree grandstand boasts a capacity of 22,400 and the venue also incorporates conference rooms, a VIP room, a restaurant area and a shop for fans of the local football team.

 

The sound system was designed by Tommex Żebrowscy Sp. J. and installed by Zeto S.A. The system is based on Community loudspeakers and Dynacord electronics. Białystok-based integrator Zeto S.A. completed the installation in time for the opening of the modernised venue, which took place in July 2014. Zeto’s Zbigniew Kaczmarczyk was project manager for the installation.

 

The main system is 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 is the largest system based on the DANTE protocol 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.

 

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.

 

The main loudspeaker system comprises forty-eight Community R2-474’s and three R2-52’s. The combination provides the dispersion patterns required for complete coverage of the stadium’s 360-degree grandstand. In addition, thirty-eight R.25-94’s and forty-one R.5-99’s provide audio for the stadium’s internal promenades and public areas around the building.

 

Twenty Dynacord DSA 8410 4-channel amplifiers provide a total of 80kW to power the Community loudspeaker systems.

 

Marcin Zimny of Tommex commented:

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.
