The Riga Circus, a historical landmark and the oldest fixed circus venue in Europe, recently underwent a transformative renovation that aimed to preserve its heritage while introducing modern amenities, notably an innovative audio system by K-array. The project, led by local integrators RJK and supported by technology distributor Tet A Tek and architectural firm NRJA, aimed to create a versatile, energy-efficient space that could accommodate various performances.

Two audio systems were installed to meet the venue's specific needs: a 360-degree coverage system and a portable system using K-array's Mugello-KH2, known for its lightweight design. “The modernised Riga Circus is a multi-purpose space and needed versatile audio support,” explains Rudolf Busmanis at Tet A Tek. “The portable system allows for easy reconfiguration depending on the stage’s location, with cabling running through the centre of the venue to provide power flexibility.”

For the fixed installation, KGEAR’s GH12 loudspeakers were arranged in clusters, covering the venue's unique spherical shape. K-array’s Kommander amplifiers power the system, which is managed via the K-Framework software. Despite the acoustical challenges posed by the building’s round architecture, the system performed well, with Busmanis acknowledging, “The technology within the products coupled with K-array's expertise enabled us to overcome the issues inherent in the structure.”

The systems were designed with energy efficiency in mind. The lightweight Mugello system can be moved easily by a single person, reducing manpower needs. Additionally, both K-array and KGEAR products convert electrical energy efficiently into sound, minimising operational costs. The flexibility of the KGEAR system allows for tailored usage based on event size, ensuring energy is only used when needed.

"The K-array system has surpassed our expectations," remarks Busmanis. “With K-array at its core, the Riga Circus is poised to continue captivating audiences for generations to come.”
