Piotr Nowinski, systems engineer at Sopot, Mega Music’s Poland-based audio/visual installation division, noted that while “another company executed the design for the new sound system” and “we were comfortable with the principles of the design,” he and his team recommended a different choice of manufacturers. “Because we have completed so many projects with the general contractor, they gave us the go-ahead to substitute manufacturers we could stand behind,” including Ashly and Symetrix.

The system consists of nearly 50 zones. Each zone contains two D.A.S. loudspeakers – one on an inner ring and a second on an outer ring. A delay separates each pair so that the signals that arrive at the spectators are appropriately signal-aligned. A handful of the zones cover the field.

A Bosch Praesideo PA system covers the new stadium’s corridors and waiting areas, which was installed at the client’s request. The Bosch system receives output from the Symetrix SymNet DSPs, allowing the client to provide reinforcement away from the grandstands as well.

Nowinski distributed the processing and power for the sound system using one control room and three node rooms distributed around the stadium. The control contains a Crest XR-20 console, which provides access to stadium technicians to adjust input sources. A laptop using Ashly’s Protea software controls and monitors the Ashly Networkable amplifiers.

The control room and the three node rooms distribute the DSP and amplifier load. Four Symetrix SymNet 8x8 DSPs, four Symetrix CobraLink units and three Symetrix BreakOut 12 expanders provide the system with open-architecture equalization, matrix routing, volume control and preliminary loudspeaker conditioning. Ten Ashly DSP-enabled ne8250PE, three Ashly DSP-enabled ne4250PE and two ne1600 amplifiers deliver power to Gdynia’s many loudspeakers.
