DLR Lampoldshausen: Modern Voice Alarm System with Dante and Clara E

At the Lampoldshausen site of the German Aerospace Center (DLR), the existing campus-wide public address system, based on traditional 100 V technology, was upgraded to a modern Dante audio network. The goal of the project was to provide flexible and reliable distribution of audio from a relatively small number of microphones and input sources to a large number of loudspeakers and output devices across the extensive facility.

The Clara E serves as the central component of the system. With its powerful routing matrix and support for up to 1,024 Dante channels, it efficiently distributes a limited number of inputs to a large number of outputs. Its redundant network interfaces also ensure stable, fail-safe operation—an essential requirement for safety-critical announcements throughout the DLR campus.

By migrating to Dante technology, DLR Lampoldshausen has future-proofed its public address infrastructure. Acting as the reliable hub between input sources and the many networked loudspeakers, the Clara E provides flexible, scalable, and consistently dependable audio distribution across the entire site.
