It can now be revealed that KV2 has provided the audio for the ‘Luz Cuenca’ multimedia immersive exhibition that combines artistic lighting techniques and an orchestral music score with 2D and 3D projection mapping, inside the ancient temple of San Miguel, in the city of Cuenca, in the Spanish mountains.
While K2 provided the audio, the visual centerpiece of the exhibition, which opened in late March this year, is powered by 20 Barco G60-W7 projectors, teamed with Dataton’s Watchout show composer software. The Barco projectors map content on the church’s walls, floors, vaulted ceilings, nooks and crannies.
Digital immersive experience specialists, Ibercover Studio, were in charge of production and content design for Luz Cuenca. They turned to AV integrators Fluge to design and supply a sound system.
Designed by sound engineer Poti Martín, the system comprises 12 EX26 2-way active loudspeaker systems evenly distributed along the walls of the nave. A further two EX26s reinforce the upper gallery level.
Low end reinforcement is provided by eight EX1.5 subwoofers distributed in pairs either side of the altar, plus a further pair left and right slightly further down the nave.
Due to the immersive character of the room, each loudspeaker receives independent audio signals which are sent via Dante, track by track, from the Watchout 6 video playback system and then processed and distributed to the loudspeakers via NST Audio DSP matrices. Finally, custom white housings were designed for all the loudspeakers to minimise any interference with the video mapping.
Jesús Catá, AV project engineer at Fluge, explained: “The main objective was to effectively and uniformly reproduce sound in space at low volumes. The required SPL levels were not particularly high since the acoustics of the church play an important role in the sound environment, giving more importance to quality rather than pressure. We selected KV2 systems because they are outstanding when it comes to delivering high-quality, detailed, transparent sound at low SPLs, and that’s not easy to do.”
He added: “The synergy between the EX26 and the compact EX1.5 subwoofer for the reproduction of the entire sound spectrum in a completely flat manner, with no drop-off at any frequency, is unique. You can hear absolutely every detail of the music exactly as it’s meant to sound, even at low SPLs.”
He concluded: “However, this doesn’t mean that it won’t reproduce higher SPLs with the same degree of success – indeed, in addition to Luz Cuenca, the system will be used for many other events with more demanding level requirements, and we know it will sound just as good.”
