Sennheiser's Spectera technology, a game-changer in wireless audio, was put to the ultimate test at the Eurovision Song Contest 2026. This article delves into the behind-the-scenes magic, showcasing how Spectera revolutionized the event's audio experience.
The Challenge: A Complex Production
Eurovision is a fast-paced, dynamic production, demanding flawless execution. Sennheiser's Spectera, a cutting-edge wireless system, was deployed to handle the audio for the host broadcaster ORF. The challenge was to provide crystal-clear sound for 150 live streams, wireless mics, in-ear monitoring, and control data.
Technical Mastery: Agorà's Role
Technical production company Agorà played a pivotal role, utilizing Spectera to create the best live sound for Eurovision ever. Valerio Motta, ESC project lead at Agorà, praised Sennheiser's involvement, ensuring confidence and support throughout the project.
Behind the Scenes: The Sound Room
The Stadthalle's sound room, led by Head of Sound Gerhard Jansa, was the nerve center. It managed mic audio, IEM audio, artist preparation, and audio distribution. Two independent mixing desks and six Spectera Base Stations ensured failsafe operation, with redundancy built in.
Spectera's Simplicity and Reliability
Spectera's simplicity in cabling and its wideband advantages were game-changers. Jonas Næsby highlighted how fibre runs and media converters allowed for optimal performance. The system's RF control center provided real-time status updates, ensuring seamless signal management.
Mic Rotation: A Balancing Act
With 42 seconds between acts, the audio team juggled mic rotations. Six Spectera handhelds, six SEK bodypacks for in-ears, and 'all-in' bodypacks with headsets and in-ear monitors were used. The bidirectional Spectera bodypack with Headmic 4 offered clear sound, while Neumann KK 105 A capsules minimized interference.
Overcoming Challenges: Fading and Phasing
Spectera's wideband technology addressed fading issues, a common problem at Eurovision. Developers Jan Watermann and Sebastian Georgi explained how they tackled fading notches and cancellations, ensuring perfect coverage. They also resolved phase issues, allowing sound engineers to mix all mics seamlessly.
A Full Circle Journey
Spectera's development began at Eurovision, addressing fading challenges. In 2026, it returned, streamlining workflows and delivering exceptional audio. Sennheiser's expertise in wireless audio, from the 80s to the present, solidified its position as a leader in the industry.
Conclusion: A Wireless Revolution
Spectera's performance at Eurovision 2026 showcased its capabilities, earning praise from engineers and production teams. Sennheiser's technology, combined with Agorà's expertise, created a wireless audio experience that set a new benchmark for live music broadcasts.
