August 2007 - In preparation for the 2007 IRB Rugby World Cup, several stadia in France have installed new high-specification
sound systems, powered by CAMCO Vortex amplifiers.
The venues are:
- Stade de la Beaujoire, Nantes: home of FC Nantes, capacity 50,000
- Stade Felix Bollaert, Lens-Marseille: home of RC Lens, capacity 42,000
- Stade de la Mosson, Montpellier: home of SC Montpellier, capacity 34,000
The first and largest of the three projects to be completed is the Stade de la Beaujoire in Nantes, a 38,000-seater ground, home
of Nantes F.C. and the most modern of the French stadia to be used for the 2007 RWC. Stade de la Beaujoire was required to
upgrade its sound systems, both PA and VA, to comply with European regulations. Nearly 100 arrayable Nexo enclosures have been
used in this 38,000-seater ground, the most modern of the French stadia to be used for the 2007 RWC.
The installation of the new system has been handled by rental and fixed installation company Melpomen, which has built an
EtherSound-controlled network, using Auvitran links and software, Yamaha matrix and mixing consoles and Nexo NX242
Tdcontrollers.
Four amplifier racks are located around the stadium, linked to each other and to the control room by two fire-resistant fibre
optic links. Each contains up to 6x Camco Vortex 6 power amplifiers, plus a back-up in each group, delivering total network
redundancy. In the event of total power failure in the stadium, the system will continue to function for 30 minutes.
Melpomen and Auvitran have also co-developed bespoke (custom) software which allows the master control room operator to check all
loudspeaker clusters and amplifiers in the four rack rooms. These amplifier "monitors" keep a real-time eye on amplifier
temperature, current and voltage at each speaker cluster. This additional level of security is necessary by regulation because
the system is performing combined PA/VA tasks.
