The Consell Insular de Formentera, presented the need to equip its new plenary hall with the necessary audiovisual systems to be able to manage the debates between the members of the island corporation during the plenary sessions and to be able to also carry out other types of institutional events. It was essential that the audio in the plenary hall could be recorded and that the sound of the system was available to the media. The project consisted of the design and implementation of a microphone system for debates, an audio recording system, a sound system and a video projection system. The main part of the plenary hall installation was the debate system for which the CCS1000D from the manufacturer Bosch was chosen. A system that works on a communication BUS and is one of the most robust on the market. Bosch systems are among the most installed in the world, and systems of this brand can be seen in the European Parliament, in the Congress of Deputies, in regional parliaments and numerous town halls. This project has been carried out in collaboration with the company Ditec Comunicaciones, S.L. of Barcelona.
