The organisers of Gymnaestrada 2011 installed an audio and communications system consisting of a RockNet digital audio network and communications infrastructure comprising an Artist digital matrix intercom and TETRA digital trunked radio from Riedel Communications.
For the event’s opening and closing ceremonies, as well as during the regular events, the organisers used a RockNet installation for distributing the audio within the stadium. Three RockNet rings transported 180 audio signals between four different stages and the FOH in the Stade Olympique de la Pontaise arena. The Swiss event specialist Skynight was responsible for planning and installation. All three RockNet rings were connected to a digital Studer Vista 5 mixing console. This was the first time a single Studer console was used to control three RockNet rings together.
"The RockNet installation allowed for maximum flexibility. We were able to easily remove stages and interfaces from the ring that weren't needed after the opening ceremony without interferences to the underlying RockNet infrastructure that was still used for the rest of the Gymnaestrada. To realise pre-mixes and pre-listen monitoring for the musicians on stage, we used additional digital Yamaha mixing desks that were also equipped with RockNet expansion cards. With the help of these interfaces cards we were able to control all channels of the RockNet network from all consoles. Furthermore, RockNet's "Independent Gain" allowed for individual sub mixes independent from the main mix", said Martin Reich, responsible for the planning on the behalf of Skynight.
Additionally, RockNet also transported the audio signals via three RockNet MADI interfaces to the OB truck of the Swiss broadcasting network TRS.
To establish a communications infrastructure for the whole Lausanne area, the organier installed a digital trunked radio network (TETRA) with two separate TETRA cells. The network provided 21 digital radio channels that were used by the local police as well as the organisers.
For the opening and closing ceremony the organisers used an additional Artist digital matrix intercom system that was integrated with the radio network via ISDN and VoIP interfaces. A total of two Artist 64 and 25 Artist control panels were used at the event.
