Swiss stadium Letziground relies on audio technology from Renkus-Heinz

After its modernization, This important sports venue in Switzerland now has the Cx61 and TX151s systems from Renkus-Heinz to deliver high-quality sound to viewers, whether in a competition or a concert.

Headquarters of FC Zurich and of the World class, the most famous athletics competition in Switzerland, he Letziground stadium has completed an ambitious multi-year modernization project that results in greater capacity to host sports competitions and concerts.

In order to offer the best audio experience to attendees, The stadium has a new sound system based on the Renkus-Heinz technology, according to the project integrated by avidec AG y AG averages .

Taking into account that the stadium's event program changes regularly, One of the requirements of the new audio system is that it be weather resistant and enough flexible how to adapt to speeches, music and public announcements.

Besides, the system had to offer constant and balanced sound pressure levels, as well as a even coverage. Los C and T series speakers the Renkus-Heinz, in weatherproof WR versions, They offered exactly what Letzigrund was looking for.

Chris Steiger, CEO and founder of averages AG, explains that “Renkus-Heinz has a wide range of speaker systems, which allowed us to find the perfect solution for this project. A few years ago we installed 48 CX61 models as near-field speakers for the audience in the back rows. This year we have expanded the system with 31 TX151 equipment to offer a homogeneous sound in all events”.

Avidec installed 31 TX151 speakers on stadium roof, as well as two units in each front field, one directed to the athletics track and another to the first row of spectators. Another one is located in the rear field and the three rear rows of seats benefit from the sound provided by the CX61 models, smaller.

“Renkus-Heinz T-series loudspeakers are versatile boxes that can be integrated practically anywhere -adds Steiger.. “They are ideal for projects in sports venues and offer exceptional sound performance in all areas of Letzigrund”. The TX151 models put Renkus-Heinz's exclusive advances into practice with their complex conical horns, that provide a beam width and constant directivity, without the problems of conventional rectangular speakers.

C series includes compact two-way speakers, like CX61 models, offering high volume output in a small enclosure, as well as low distortion and high performance power at high frequencies.

Avidec AG has been supporting the stadium sound system for more than seventeen years.. The installed models adapt perfectly to the existing infrastructure, providing a high level of sound pressure and dispersion angles.

“With this first conversion, we have installed a new sound in the 40% from the spectator stands. Next year we plan to integrate more TX151 for the middle row seats, in the last and in the field”, concludes Steiger.
