Bucharest National Opera audio is updated with K-array

The audio system of this cultural center in Romania has 18 speakers K-array This is the KY102X and 8 subwoofers Thunder KS3P I, in addition to the Anakonda KAN200+. The entire system is powered by Kommander KA208 and KA104 amplifiers.

The team of the Bucharest National Opera collaborated with local distributor and integrator Senia to implement a permanent K-array solution and upgrade your sound infrastructure. The new equipment offers design and sound quality.

This institution is a key piece of Romanian cultural heritage and, recently, has undertaken a project to modernize its audio infrastructure focused on optimizing performances and preserving the historic interiors of the venue. The venue relied primarily on rented live sound systems. Often bulky and unsuitable as a permanent solution, These ran the risk of detracting from the grandeur of the space and distracting the public..

“One of the main challenges we faced at the Opera House was finding the balance between the requirements of a high-performance audio system and the need to maintain the original architecture and features of the venue”, reflects Ionut Mavrichi de Senia. K-array's slim profile speakers were selected for their ability to blend into their surroundings.

He main AC system has twelve speakers Kayman KY102X, six units per side, ensuring uniform sound distribution throughout the room.

To deliver deep, resonant bass without cluttering the space, four have been suspended from the ceiling subwoofers Thunder KS3P I, with four more units available on mobile platforms for flexible placement, according to the needs of the performance and the event. Audio coverage at the balcony level is achieved with six additional Kayman KY102X speakers, ensuring a uniform listening experience for the entire audience. Front-fill is provided by ultra-flexible speakers Loved the KAN200+, discreetly mounted at the front of the stage, that transmit audio to those sitting closest to the action without interfering with sight lines.

The entire system is powered by amplificadores Commander KA208 and KA104, allowing facility technicians to easily control and monitor system performance through the software K-Framework 3.

Custom finishes in RAL colors were applied to the Kayman wall mounted speakers, integrating them with the interior design of the opera house. Incorporating a system Pinnacle Standalone in the lobby provides a consistent audio solution for smaller events and meetings.

The acoustic calibration of the system was a fundamental part of the project, given the complex sound dynamics of the venue, including multiple balconies and highly reverberant surfaces.

“The calibration process presented several challenges, mainly, ensure balanced sound distribution throughout the room and, in second place, achieve homogeneous low frequency coverage in the audience area without interfering with the orchestra pit or stage”, says Paolo Capponi, K-array Product Support Specialist.

To address these challenges, The K-array and Senia team opted for a cardioid suspension subwoofer configuration, which allowed better control of low frequency dispersion, while minimizing unwanted low frequency energy on stage. Through extensive testing, using multiple measurement microphones throughout the theater, the team achieved a precise and linear frequency response, ensuring not only a uniform and balanced sound experience for the audience, but also precise calibration for technical room engineers.

This project is the first major audio upgrade at the Bucharest National Opera since the 1970s. 1990. By modernizing the venue's audiovisual infrastructure, The installation sets a new benchmark for cultural institutions seeking to integrate advanced technology without compromising their own heritage.
