Dynacord, Electro-Voice solution for new arena complex

Dynacord, Electro-Voice solution for new arena complex

The former Alb Stadium in Heidenheim, Germany, has been expanded and renovated, and is now known as the Voith Stadium in recognition of the region’s largest employer.

A year in redevelopment, the stadium now has a capacity of 10,000 spectators, with the option of further expansion to 15,000.

The entire sound reinforcement system has been replaced. The client opted for a sound reinforcement concept proposed by Ingenieurbüro Kummich & Weißkopf of Bopfingen, with ELK GmbH of Dischingen assuming responsibility for the configuration and commissioning of the installation and training staff in its use.

The new sound reinforcement system, comprising ELA components from DYNACORD and pro audio systems from Electro-Voice, serves all areas of the stadium – from the access roads to the grandstands, corporate boxes and ancillary rooms of the stadium itself.

In the control room, an audio mixing desk is installed for the playback of music from a variety of sources. For the control of the parameters, a TPI-12 touch panel from Electro-Voice has been provided, which is integrated into the IRIS-Net network. In the Business Club housed in the main grandstand, another TPI-12 touch panel has been installed and it, too, is fully integrated into the audio control network.

The entire control and equipment concept is based on a main control centre in the south grandstand furnished with two 19-inch cabinets and a further such cabinet in the north grandstand opposite.

Both control rooms are equipped with Dynacord Promatrix components and P64-1500 matrix controllers, and linked by fibre-optic cables. Control data is transmitted via Ethernet and audio data via CobraNet. An analogue backup for control and supervision contacts offers additional security.

The loudspeaker spec in the stadium features Electro-Voice ZX5+PI and Dynacord D-12-PI series models, powered by Dynacord DSA 8405 and 8410 multi-channel power amplifiers.

The simulation values for the loudspeaker installation were corroborated by system engineer Dieter Kellner, who reported that “all the conditions laid out in the model measurement protocol were fulfilled”.
