Officially the world’s largest stage, the 3,000sq-m offered by the1,900-seat Friedrichstadt-Palast in Berlin also boasts the largest proscenium in Europe. Attracting visitors from around the world, the venue recently added an L-Acoustics L-ISA immersive sound system to support the increasing variety of shows being stages.

Productions frequently blend music, dance and acrobatics, often with more than 100 performers. From Cirque du Soleil to original shows mounted exclusively for the Palast, the performances always match the scale of the venue itself. Hosting up to eight shows per week, the theatre draws around half-a-million guests annually, cementing its status as Berlin’s most frequented.

 The venue was originally opened as a market hall in 1867 before being converted into a circus in 1873. Closed in 1980 with foundation issues, the Friedrichstadt-Palast was reopened in a newly built structure in 1984 as the largest and most modern performing arts centre in Europe. Mounting performances to rival the complexity of Las Vegas, programming ranges from children’s shows, festival galas, and guest performers, in addition to the Palast’s own Ballet Company, show band, and Youth Ensemble.

L-Acoustics Certified Provider FeedBack Show Systems was called on for the installation of an immersive sound system that needed to respect the strict preservation laws governing the theatre and integrate with its existing audio control. This includes existing market tracking solutions and providing comprehensive audio coverage throughout the venue while enveloping audiences in immersive sound to help fans better localise performers during the intricate performances.

FeedBackHead of Audio Dennis Dackweiler has previously designed systems using L-Acoustics, and says that it is ‘eye-opening to see what can be done when you change from stereo to L-ISA – it creates more space and more separation, and that’s what the venue was aiming for – a huge soundscape to bring the audience closer to the performance’.

Dackweiler and the team at FeedBack worked with Martin Rode and Martin Wurmnest from the Application team at L-Acoustics to design the L-ISA configuration. Rode was particularly impressed with the quality of collaboration with the teams at Palast and FeedBack.

‘During production meetings to discuss loudspeaker placement, the entire team of set designers, lighting designers, and art directors were involved, and all were open and fully focused on finding the right compromises to ensure optimum performance of the L-ISA technology,’ he says.

The 270° audience area presented challenges addressed using L-Acoustics Soundvision 3D audio mapping software to model optimum loudspeaker placement for comprehensive coverage. ‘Our goal was to ensure dynamic distribution and localisation of the artists on stage. L-Acoustics K3 in an L-ISA configuration proved to be the ideal solution to deliver exceptional, balanced sound throughout the entire audience area,’ says Friedrichstadt-Palast Technical Director, Thomas Herda.

The L-ISA Scene system consists of 102 L-Acoustics K3, including nine hangs across and extending beyond the stage, with six further surround hangs of L-Acoustics K3 placed at the side of the venue. Two X12 are placed below the K3 Extension system for extension near fill. Two arrays, each consisting of a single A15 Focus and A15 Wide, provide fill for the audience areas located to the far left and right of the stage. The spatial distribution of sound is handled by an L-ISA Processor II with a 64-output licence.

A scaled-down L-ISA configuration using L-Acoustics X8 and 5XT coaxial loudspeakers with Syva Sub is installed in the theatre’s on-site studio to support immersive audio mixing in pre-production. This enables the sound design team and the musical department to accomplish much of their pre-production work without blocking the entire venue while the previous show was still running.

‘Early in 2022, we tested the scale simulation during a mixing session in the studio to validate that the creative ideas would play out well in the dimensions of the large venue,’ Wurmnest says. ‘It worked like a charm. When we moved to the full venue, we only needed minor adjustments on EQ levels, and all of the object positions that we simulated translated perfectly to the large stage.’

‘L-Acoustics was the ideal choice for us. In addition to the generally outstanding sound quality, the acoustic localisation provided by L-ISA spatial sound has helped us better connect the visual events on stage with the acoustic experience,’ concludes Herda. ‘The audience can now see where the musicians and performers are on stage and hear them with pinpoint accuracy. This creates an even more intense, lively show experience. Bringing to life the sonic landscapes we’ve always dreamed of.’

‘We are delighted to announce that we have gained the Friedrichstadtpalast as a partner,’ says Sebastian Wittrock, Sales Manager L-Acoustics. ‘I am very proud to be a part of this journey. The Palast in Berlin is now a top international reference for us, and we would like to thank them for their trust and cooperation.’
