The new system Christie lives Audio 7. fascinates to the public of Seehof Cinema in Switzerland

The new system Christie lives Audio 7.1 fascinates to the public of Seehof Cinema in Switzerland Kino Seehof in Zug, Switzerland, offers its viewers an unsurpassed movie experience with the latest technology, audio and projection. Attendees to the rooms, which already enjoyed an excellent digital projection system, have been time amazed by the quality of sound of amplifiers and loudspeakers of Christie systems.

Small but excellent, is the description that best defines the second generation of cinemas Gotthard and Seehof, property of Thomas Ulrich and located in the Swiss town of Zug. Ulrich is an entrepreneur who always aspires to the best for their independent cinemas: wants them to look traditional, but modern and targeted both art and entertainment, which leads him to combine classic Swiss cinema, regional content and international films of Auteur cinema with blockbuster of Hollywood and opera or ballet.

With the passage, long since a few years, to digital projection technology, cinemas might exhibit alternative content and formats in which music is a key element, such as concerts and performances of opera and ballet, and for those who achieve the perfect sound was essential. Before the challenge, Ulrich chose to update your audio system, undertaking the search of a solution that offered a flawless sound reproduction in all applications and that got to immerse the viewer in every scene. Regardless of what is projected on screen, an explosive action scene, the sound nuances of an operatic aria or monotonous rattle of the express of the Gotthard, the system had to offer the maximum quality and performance sound at any volume.

Ulrich says that "anyone can play a sound at full volume, but for me it was important to have an audio system that replicate the tones in all its nuances and thus create an experience fully immersive. Seek Protronic AG Council again because we had already had good experiences with Christie. In particular, when we update the digital projection technology combining Christie CP2220 Doremi DCP-2K4 server.

Immersive experience

Patrik Engler, CEO of Protonic AG, a veteran Christies partner, said that "our aim was to get all the advantages of digital cinema and achieve the perfect harmony of video and audio. In addition to aspects of operation, it had to take into account the architectural conditions of the room. And everything led us to Live Audio as the perfect solution. "With their amplifiers Class D high-performance, compact linear design of the speakers and technology ribbon (Ribbon transducers) driver, could create a Sonic experience fully immersive without having to resort to expensive sound systems, allowing the Exhibitor to deploy the full potential of digital cinema".

In contrast to the traditional Horn loudspeakers-based audio systems, Live Audio uses a ribbon driver, much more concise technology that responds directly to the audio signals achieve unparalleled sound clarity. And the most important thing is that considerably reduce distortion and have an ultra-fast transient response, what makes an ideal solution for applications that require maximum quality, as it is the case of the film, where it is crucial that all that happens on the screen (conversations, effects, music and other audio content) reach the public all the naturalness and authenticity as possible live audio.

To get 7.1 multi-channel audio recommended, Protronic resorted to a CDA-3 amplifier and three front speakers go-1 (one on the left, another in the middle and a third on the right), as well as a CDA-5 amplifier and a S218 subwoofer for the LFE channel. To reproduce surround sound front and rear were installed a CDA-3 amplifier and three LS-3Ds speakers left and right. Finally, he opted for sound AP-20 (Datasat) processor.

The structure of the film made difficult the installation of the front speakers, which, as he explains Engler, "were adjusted to fit into an already existing, but lacking access in the back baffle", forcing technicians to remove the screen before dismantling the old speakers, adjusting and installing new, finally, restoring the screen into place.

Room acoustics

Another problem was the acoustics of the room, embodied in a fairly flat resonances. "We use sound absorbers and the angle of reflection of the speaker lives helped us enormously to eliminate virtually all these flatter echoes," says Engler.

Engler concluye reafirmando su satisfacci n con el sistema Vive Audio de Christie, que ha permitido ofrecer al p blico un concepto de sonido inmejorable que tiene en cuenta las necesidades m s exigentes, pero tambi n el bolsillo. Nuestra meta era ofrecer una experiencia cinematogr fica perfecta, en lo visual y en lo ac stico, en las 221 localidades de la sala, y lo conseguimos incorporando el sonido Vive Audio a la proyecci n de Christie. La respuesta de la audiencia no ha podido ser m s positiva .
