Accor Arena, main hall sound system — Paris

Across the 55,000 m² of this Paris venue, the modernisation of the audiovisual infrastructure is being carried out step by step, without interrupting the operating calendar. In 2022, the Accor Arena entrusted Scenarchie with the overhaul of the audiovisual IP network serving its public and partner areas, an infrastructure that had become heterogeneous and whose supervision needed to be entirely rebuilt.

Scenarchie drew up the technical specification for the operation and acted as project manager, from the survey of the existing network through to replacing the switches and integrating the plant rooms. The chosen solution gives the operator an intuitive, configurable graphical supervision interface: it displays the network topology and nodes, gives direct access to a switch's interface, continuously monitors traffic — throughput, packet loss, link failure —, manages DHCP deployment and reports alarms.

The assignment continued with the replacement of the fixed sound system of the main hall, designed to remain usable in every configuration of the venue — from athletics to ice sports, from end-stage concerts to in-the-round — without any handling between events.
