The projection room is one of the highlights of this new venue, because, as it was not symmetrical, there was no recommendation for any ceiling height, and large inverted rays obstructed the view.

At the end of 2017 finished in Argentina the construction and installation of Disney Latin America, building in which 258,333 was included, of the 19,375 square feet, 44 for post-production of video divided into 29,2 spaces. This headquarters is located in the city of Pilar, at XNUMX miles from Buenos Aires.

Giner, an audio and acoustic company from Sao Paulo - Brazil, was the integrator in charge of audio and video solutions. He was hired for the execution of the project after the work done for the Disney radio station in the World Trade Center, which the team of José Carlos had executed in 2009. The project for Disney, the new headquarters in Latin America, included a usable area of ​​258,333 square feet with 950 employees. Of this total, Giner has 19.375 square feet divided into 44 spaces for the execution of the project.

In addition to acoustics, Giner was responsible for the management and work of all technical areas, including air conditioning, electrical installations, architectural design and interiors. The project included 23 video editing workstations, ten Pro Tools voice and voice studies, a radio equipped with two studios, nine technical rooms and a movie theater, providing acoustic isolation for management and for the President rooms and vice president.

"The client needed a projection room with innovative concepts to present the new features of the films to specialized media and business partners, making use of the new Dolby Atmos projection technology, which is the heart of the company," said Giner. .

He added that "Despite having been in the market for 35 years in this field, we felt the need to investigate the latest generation of electroacoustic and audio resources to introduce them to our projects." Giner visited the technology fairs of audio and video for two years, highlighting the ISN 2015 / 2016 in Amsterdan, as well as others in America and Germany.

The architecture was entrusted to the office of Alexandre Wissenbach who worked in a consortium with the local workshop, an essential condition to translate and adapt the project to Argentine standards and regulations. According to Giner, the choice of the location of Disney's headquarters in Latin America benefited from the favorable economic situation derived from the first months of Mauricio Macri's government. "Currency exchange rates helped, I had no way to import equipment in the previous government of Cristina Kirchner," Giner recalled.

From the facade of the glazed building you can see the road and have preserved the panoramic openings between the studios.

"As the large structure was ready, we had to close openings here and there to contain leaks and maintain acoustic comfort," Giner said. The company opted for some elements manufactured in Belgium that allowed structural decoupling. Walls, claddings and floors were uncoupled from the large structure, which helped maintain the degree of structural insulation at sound reduction ratios greater than 55 dB within the rooms and 60 dB within the cinema room. An initial technical report showed the results of the insulation simulations carried out in programs such as SONARCHitect ISO, Insul, WinFlag and CDM Solids.

The movie theater received special attention, as requested by senior management. For her, innovative design features were presented, never before used in other rooms, as well as new concepts. The main idea behind this was to design a diffuse room instead of an absorbent room and it was requested that the various speakers used with Dolby Atmos technology remain invisible to moviegoers.

To meet these demands, new acoustic devices were designed in England and the United States. "We asked the designers to help us create something unprecedented to control the sound fields, remaining exclusive at the same time," said Giner.

For the FM radio project, these same elements provided a hallmark sonic personality. "Very welcome by the listeners who felt the changes introduced in the sound of the radio according to the surveys conducted by the station."

Disney FM Radio
After several years operating from an old building located in the center of Buenos Aires, Argentina, Radio Disney needed to move to a new customized facility on the outskirts of the city, which meant an excellent opportunity for technical remodeling used the latest technological advances .

Giner, technical manager of the entire project, requested the creation of a new project from scratch, having had to use only the latest technologies available to his partner Ciro Riskallah, owner and chief engineer of ABC Telecom Brasil, a company with more than 30 years of experience in the transmission industry.

But the reality was not so simple: Disney Radio requested 2 studios with all kinds of facilities, including the ability to run the radio from any studio at any time. In addition to that, there were the requirements of the Argentine union of transmission employees that complicated things.

Ciro and his associates Silvano Purin and Marcelo Cacheiro, both engineers with more than 30 years of combined experience in the transmission market, began to evaluate the proposed scenario and concluded that the topology should be a centralized TOC that would host all the servers, processing audio and distribution equipment, STL and telephone systems.

The project was built around GatesAir's Vistamax audio management system, which proved to be the most suitable for this application. The core of the system is a VMConnected Network Envoy frame loaded with spare power supplies and controller cards, two digital I / O cards, an analog I / O card, two hub cards and a logic I / O card.

Each studio is equipped with a GatesAir NetWave digital network console, which features a PRE99-1424 dual router kit that provides source selection for two attenuators. This function allows the operator to select virtually any of the source signals connected to any of the consoles or sources connected to the Envoy frame.

In addition, a single source selector PRE99-1372 was installed in each study to select which of the studies would currently be used for on-air applications. The connections between the 6 studios and the TOC are made through the CAT6e cabling. VistaVue software graphically manages all workflows and provides even more flexibility to the entire system. Dispositions for emergencies were also deployed.

Although it is very unlikely, the catastrophic failures that affect the Envoy system can not be ignored. There are both analogue and digital audio cables from each studio to the TOC for use in such situations. To simplify the use and obtain good results from the Neumann microphones (another customer requirement), Symetrix Voice Processor 2x was chosen as the MIC processor.

A spare GatesAir IP-Link 100 receives the program from an Orban 8600 FM processor and sends it to the transmitter plant via two different routes in a main / alternative configuration. For remote transmission, the Comrex ACCESS 2USB proved to be the best option due to its ease of operation and versatility.

Jose Carlos Giner pointed out that it was a Brazilian company that designed and developed a cutting-edge project in Argentina in a very difficult scenario for civil construction and integration industries under governmental changes.

"This project generated many opportunities and jobs in two years. By providing work to more than 250 professionals, the work was developed with engineers, architects, technicians and assemblers from Brazil and Argentina and constituted a unique opportunity to work on one of the most important and innovative Latin American projects in the years 2016 and 2017, Concluded .
