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 technical marvels and the human stories behind the scenes, showcasing how Spectera not only met but exceeded expectations. From the Stadthalle's sound room to the vibrant atmosphere of the contest, Spectera's impact was profound.
A Technical Triumph
The technical prowess of Spectera was on full display at the Stadthalle. With four active Base Stations handling 150 live streams, the system delivered crystal-clear audio and seamless control data. The technical application engineering team, led by Jonas Næsby and Volker Schmitt, played a pivotal role in ensuring the system's smooth operation. Schmitt highlighted the anticipation surrounding the 70th Eurovision, emphasizing the industry's role in showcasing cutting-edge technology.
Valerio Motta, the ESC project lead at Agorà, praised Sennheiser's involvement, stating that their support made the audio team feel confident. The Stadthalle transformed into a spectacle, with lights, lasers, and sound, thanks to the collaboration between ORF and Agorà.
Behind the Scenes: The Sound Room
In the sound room, a dedicated team fine-tuned every detail. Head of Sound Gerhard Jansa and his team managed mic audio, IEM audio, and artist audio preparation. The sound room's failsafe operation, including two independent mixing desks, ensured uninterrupted performance. Six Spectera Base Stations, with their scanning and spare capabilities, provided comprehensive coverage throughout the venue.
Næsby praised Spectera's simplicity in cabling the arena, utilizing fiber runs and media converters for optimal performance. The DAD antennas, mounted behind the stage, guaranteed perfect coverage as artists entered from behind the video wall.
Seamless Mic Rotation
The audio team's agility was crucial, with only 42 seconds to switch between acts. Spectera's handheld and bodypack rotations, along with in-ear monitoring, ensured a seamless experience. Næsby highlighted the bidirectional bodypack with the Headmic 4, enhancing sound quality in front of PA systems and wind machines.
The upcoming release of the Neumann KK 105 A capsules showcased Spectera's adaptability, catering to various artist preferences.
Overcoming Challenges
Schmitt shared an incident during rehearsals, where talent on stage couldn't hear themselves. Spectera's software allowed for quick issue resolution, ensuring calm and efficient problem-solving. The system's ability to detect RF health deterioration and provide real-time feedback was a game-changer, especially in dynamic production environments.
Spectera's Evolution
The journey of Spectera began at the ESC in Copenhagen in 2014, where fading issues prompted the development of wideband technology. Jan Watermann and Sebastian Georgi, WMAS developers, recalled the challenges and the birth of Spectera's wideband approach. The system's multiplexing and time slot ideas addressed fading notches and cancellations, ensuring reliable performance.
Watermann addressed phase issues and clock synchronization, a common challenge in digital systems. Spectera's TDMA technique and synchronized internal clock eliminated phasing, as demonstrated by the open microphone test.
A Legacy of Excellence
Spectera's impact at Eurovision 2026 was profound, earning praise for its audio clarity, wireless performance, and RF stability. The system's ability to streamline workflows and deliver exceptional audio for artists and audiences solidified its position as a game-changer in the industry.
Næsby proudly highlighted Sennheiser's legacy, from wireless audio in the 80s to the cutting-edge Spectera technology at Eurovision 2026.
