Austria - Situated amid Austria's picturesque wine country, the Mörbisch Lake Festival is a cherished celebration of culture and performing arts. The location has been a regular event for nearly 20 years and each year draws thousands of festival-goers.
The festival's centrepiece is a floating stage that appears to levitate above the tranquil waters of Lake Neusiedl. This stage is integral to the festival experience. As dusk falls, and lights shimmer on the water, the stage morphs into an enchanting spectacle that captivates all who witness it. This year, the mesmerising ambiance of Mörbisch has been elevated further through collaboration with L-Acoustics.
Over the past 20 years, this venue has evolved from a simple site, into a vibrant centre for performing arts. Transitioning from opera to musicals, it now hosts productions such as this year's Mamma Mia! and boasts a capacity of 6,200 people. In response to the escalating demands of an expanding venue and increasingly ambitious productions, the Mörbisch Lake Theatre had identified a pressing need for a high-quality sound system, tailored to fit the layout of the stage.
In each year gone by, a new stage and audio design had been brought in to align with the festival's changing themes. However, after conducting numerous demonstrations to perfect the setup, the decision was made in September 2022 to use the L-Acoustics A15 as the permanent sound system, due to its compact design and 110-degree audience coverage.
Subsequent demonstrations were conducted to refine the setup, ultimately solidifying the decision to go with the A15 system.
Five hangs of three A15 speakers were deployed to achieve complete spatialisation across the entire plateau. Four centrally flown KS21 subwoofers were added to enhance the lower end of the audio spectrum.
With a significant 25m gap between the edge of the stage and the audience's front row, and an additional 60m of audience area to span, sound spillage is effectively minimised. The L-Acoustics A15 emerged as the optimal choice to retain high frequencies.
“The A Series was the perfect match for this project - providing a full range of audio from a compact set of speakers,” says Raphael Rupprecht, technical sales manager and ACC at Signal. “Its size was a key factor, given our stage's truss constructions are also used for set designs, meaning large speakers were not an option. One of our biggest surprises was how well the A Series handled the wind, as it typically blows from the water towards the audience. This can cause problems for line array systems, particularly with higher frequencies being blown away. However, the A Series system successfully managed these conditions, ensuring a consistent and high-quality audio experience for all attendees.”
As the venue gears up to continue its series of shows, the feedback has already been overwhelmingly positive. Both Thomas Hofstädter and the L-Acoustics application project engineer Christian Schmid are extremely pleased with the new sound system. “It's a vast improvement over previous years and we're excited for our audience to experience it," concludes Rupprecht.
