World Conference Center Bonn: Perfect Coverage with Fohhn Beam Steering Systems

Focus Modular and Linea Focus systems are installed in the Plenary Chamber.

Only a few months after the final sitting of the German Bundestag, parts of the parliamentary building in Bonn re-opened as a conference facility during the autumn of 1999. The present-day World Conference Center Bonn includes, among other things, the former Plenary Chamber. Today, this venue offers event space for up to 1,230 people: The Plenary Chamber itself, with its benches for parliamentary groups, the government bench, the Bundesrat and presidium, has 734 seats, while a further 496 seats are available in the visitors’ gallery.

In 2018, the Plenary Chamber had a new, cutting-edge sound system, which was specially adapted to the room – and manufactured by Fohhn. The system was planned by engineering company GRANER + PARTNER and implemented by Salzbrenner media.

The centrepiece of this installation comprises two Focus Modular Beam Steering arrays, each several metres in length. These have been mounted on either side of the imposing rear wall behind the presidium. Each array consists of an FM-100 high frequency module and three FMI-400 low-mid modules, along with further FMI-400 “dummy enclosures”, added purely for visual reasons.

In the low frequency range, the Focus Modular systems are supplemented by four Arc AS-31 subwoofers, which have been installed in the underbody under the lectern. Four compact XS-30 subwoofers serve as side solutions when needed.

Six Linea Focus DLI line source systems with AES/EBU inputs, (two DLI-130 AES and four DLI-230 AES), have been mounted on ceiling pendants. These serve as delay loudspeakers for the gallery.

High frequency enhancement for the outermost front seating is provided by compact LX-10 loudspeakers, which have been added under the gallery, at the corners.

We congratulate all participating companies on this successful project.
