Stadion Miejski, located in Łodź, Poland, is the home stadium of football team Widzew
Łodź, one of Poland’s best-known football brands. Designed by architect Jacek
Ferdzyn, Stadion Miejski is an entirely new construction with an all-seater capacity of
18 018. The design meets the requirements of UEFA Category 3 classification, with
the option of adapting to higher categories if required.
The contract for design and installation of the stadium’s sound systems was awarded
to Tommex Żebrowscy Sp. J. The first stage of the system’s design was a detailed
EASE acoustic simulation for loudspeaker selection and placement.
For Stadion Miejski, Tommex again chose Community’s R SERIES loudspeakers for
their high power, outstanding intelligibility, controlled coverage and all-weather
reliability. Flown from the roof canopy in a distributed configuration, Tommex achieved
ideal coverage of the stadium’s four stands with thirty-eight R.5-96MAX 12-inch high
performance coaxial two-way loudspeakers. An additional two R.5HP compact voice-
range optimised three-way loudspeakers were deployed to cover the playing pitch.
The system is operated from the commentator room, where a Behringer X32 digital
console with DANTE card controls all sound signals. Adjacent to the console is a PC
with IRIS-Net software, customised for Stadion Miejski. This allows for continuous
monitoring of all equipment, and adjustment of parameters for particular zones of the
system. The commentator room equipment also includes CD/MP3 players, wireless
microphone receivers, a digital feedback eliminator and active monitor loudspeakers.
The audio feed from the commentator’s room is sent to two amplifier rooms, located
in opposite stands. Each has three Dynacord DSA 8410 four-channel class D power
amplifiers, equipped with IRIS-Net RCM 810 control modules, and one Dynacord P64
modular matrix. The P64 allows for remote control of systems devices, signal
processing and connection of the entire system to the fibre network. Communication
between the commentator room and the two amp rooms is via the DANTE protocol.
In addition to the commercial audio system, Tommex also installed an APS Aprosys
voice evacuation system, from Swiss manufacturer g+m electronics. In emergency
situations, the evacuation system assumes full priority, automatically muting
commercial signals and sending alarm messages to all evacuation zones, including to
the spectator stands and playing pitch through the Community loudspeaker system.
Marcin Zimny, Commercial Director of Tommex, commented, “The combination of
equipment in Stadion Miejski has been well proved for quality and reliability in the
many stadia we have completed across Poland. The latest R.5-96MAX has not only
maintained R SERIES legendary all-weather reliability but also raised the audio quality
to an outstanding level.’
