01 — Services
We design, supply, install and run the technology for live performances — equip the venues where people perform every day.
Concerts, festivals, civic and corporate events.
Stage technology for cultural centres, theatres and concert halls.
Systems that have to work every day, for years.
02 — From the archive
Photographs from events: what stands behind a performance — from truss towers and loudspeakers to a microphone on its stand.
Truss towers, flown loudspeakers and lighting around the park pavilion: technology that has to work under an open sky, from soundcheck to the last song.
An intimate stage needs unobtrusive technology: microphones on drums and double bass, floor monitors and warm light that never distracts the musicians.
Black stage drapes, microphones for the vocal group and a PA system turn a sports hall into a stage.
With projection and light, the park pavilion becomes a canvas for a city event.

Reference · festival · about 20 years
Terezijana is a major summer festival in the centre of Bjelovar. BOLERO’s technical work at the festival spans about twenty years — not only on the main stage but on all of its stages: sound reinforcement, stage lighting, video and visual systems and 3D projections, for concerts by many Croatian performers. At the festival BOLERO has worked in cooperation with MEGA SOUND, a music equipment hire business from Virovitica.
3D view Illustrative 3D view — town centre from OpenStreetMap; stage positions, equipment and audience are illustrations, not a particular edition Drag with the mouse to look around
Bjelovar was founded in 1756 as a military centre, and its regular street grid still gathers around the large park on Eugen Kvaternik Square, with the stone music pavilion at its heart. During Terezijana this is the festival’s core.
During Terezijana the town centre becomes a festival ground with several stages, food zones and fairs. The layout has changed from edition to edition; the view places stages in the park, on the Korzo and in Preradovićeva Street as an illustration — not as a record of a particular year or as a list of BOLERO’s services per stage.
The main stage in the park draws the festival’s largest crowds. Here sound, light and image have to work as one system — night after night, for very different performers.
Shown: the main system flown from PA wings, a line of subwoofers in front of the stage, delay loudspeakers deeper in the park and the front-of-house mix position in the middle of the audience — a typical configuration for a large open-air audience. The view is generic; the actual equipment changed with editions and stages.
Moving lights, LED screens and projections turn the town centre into a stage. The projection on the pavilion only illustrates the technique — it does not depict a confirmed BOLERO projection or a specific edition.
BOLERO’s work at Terezijana spans about twenty years — on every festival stage and for concerts by many Croatian performers. Individual editions, years and performers will be listed once we have confirmed them with documentation.

During the renovation of Dvorana europskih prvaka in Bjelovar, BOLERO carried out a professional installation of the sound reinforcement system. Hanging loudspeaker mounts were installed on the hall's existing steel roof structure, arranged in two separate suspended groups.

Bjelovar's landmark sports hall was renovated in the City of Bjelovar project “Interior renovation of the sports hall in Bjelovar”, officially completed on 16 June 2026. The building renovation was not part of BOLERO's work.
A large volume, hard surfaces and distant stands make sound reinforcement in a sports hall demanding: loudspeakers belong high up, clear of the playing area and sightlines. These are general principles of sports-hall audio, not measured results of this project.
The loudspeakers are mounted on two separate suspended support structures high beneath the roof. The supports hang from the hall's existing steel roof structure — BOLERO did not build the roof structure itself. The equipment thus sits permanently well above the playing area and the stands.
The system comprises FBT Mitus 152 passive two-way loudspeakers, Dynacord L2800FD amplifiers with integrated DSP signal processing and Neutrik connectors.
BOLERO installed the sound system to serve the entire audience seating area. Suspended loudspeakers connect the central hall space with spectators in the stands, keeping the playing area clear for sports and other events.

Reference · churches and sacred buildings · sound
BOLERO installed the professional sound system in Bjelovar’s cathedral: slim grey column loudspeakers on the walls, discreet in the Baroque space. The cathedral’s architecture and its renovation are not BOLERO’s work.
3D view Illustrative 3D view of the restored interior — estimated proportions, not a measured model; paintings, frescoes and stained glass are illustrations
The late-Baroque single-nave church was begun in 1765 (completed 1770–1771; sources differ) and has been the cathedral of the Diocese of Bjelovar-Križevci since 2009. The nave is about 20 × 12 m, with a rounded sanctuary behind the triumphal arch and the organ loft at the west end; it holds about a thousand people.
A high vault, stone and plaster prolong the reverberation: speech and singing easily become unintelligible in the back rows. Sound in a sacred space has to be intelligible and almost invisible. These are general principles, not measured results of this project.
BOLERO installed a professional sound system with AVE Audio LIVE XC series column loudspeakers — slim grey columns on the walls, discreet against the white walls and gilding. One stands on the north wall right beside the pulpit, at the height of the Stations of the Cross.
Its counterpart is on the opposite wall at the same height, by the side altar, and another column stands by the organ loft. The system serves liturgy, speech and music in a protected monument; the cathedral is one of more than ten churches with BOLERO sound systems.
