Nexo M6 future-proofs performance in visionary Swiss hall

Work has just been completed on a major revamp of the Rosey Concert Hall at Institut Le Rosey near Lausanne, Switzerland. A Nexo GEO M6 system has been deployed at the 900-seater venue at the heart of the Paul and Henri Carnal Hall, a futuristic building by architect Bernard Tschumi completed two years ago in the grounds of the exclusive Rollé school.

PaulHenriCarnalThe auditorium, designed by Arup Acoustics, is dedicated to classical music, welcoming world-famous orchestras such as the St Petersburg Philharmonic. ZAP Audio was invited to design a PA system for this elegant hall. ZAP director Frédéric Walder recalls the process, which started in 2014. “Originally, Le Rosey wanted the hall to be unamplified with only speech reinforcement capability, so we installed a small Active Audio system. Then the remit for the venue was expanded to include cinema presentations in surround sound, and concerts with bands and artists from the school. We were looking for a main PA at around the same time that Nexo launched its new GEO M Series, a scalable low-profile line array which suited the venue perfectly.”

Frédéric Walder used Nexo’s proprietary NS-1 design simulation software to design a LCR system with surround, which has been installed by Auditech.

For the main PA, he deployed two arrays each with 12 GEO M6 cabinets, flown from a dedicated M6 bumper.  Sub-bass is provided by two Nexo RS15 subs.  An additional four GEO M620s are used for frontfill. Stage monitoring is handled by Nexo PS10-R2 wedges.

For surround, there are 10x GEO M620 cabinets positioned around the auditorium. For the total of fifty GEO M6 cabinets and subs, the amplification is Nexo NXAMP4x4/NXAMP4x1 units, fitted with Dante cards to provide network functionality.

“Although the surround speakers are fixed, the main PA arrays can be easily taken down if necessary, lowered directly into the custom-designed flightcases. The network allows the Hall to move the front-of-house control to a variety of positions,” explains Walder.

“The acoustics are magnificent, and, with the addition of the GEO M6, I would consider this alongside the KKL in Lucerne as the best-sounding modern concert auditorium in Switzerland.”
