At the third edition of Research To Business, the industrial research show that was held in Bologna on the 3rd and the 4th of May 2007, RCF was invited to display, inside the ASTER's stand, the innovative intelligent speaker system made in connection with the Regional Program for Industrial Research, Innovation and Technological Transfer.

RCF's intelligent speaker system project is one of the 20 chosen by ASTER (the consortium between Regione Emilia Romagna, Universities, Research Corporations and Companies) as examples of successful enterprise research. 
As a matter of fact in 2004 RCF presented a project regarding an innovative sound amplification system able to analyze the surrounding environment's characteristics altering, by auto-equalize itself, it's sound emission for an optimal output in every kind of circumstance.  RCF's R&D Team, cooperating with Padova's University and AEB Lab in Bologna, completed the project and made an intelligent active speaker
The innovative prototype is able to change it's equalization analyzing the environment's characteristics in order to adjust the listening in reverberating and noisy spaces. By cleaning the sound output from the environment factor, the speaker developed by RCF gives incredible quality benefits for both music and speaking listening.

The most intresting applications for this system are in pubblic address systems (train stations, airports, malls, ect.) where a system able to spread perfectly intelligible messages in every kind of situation represents an extremely important evolution in terms of security and correct information communication.

RCF applied the technology developed for this project also to a speaker, which is on the market today, for concerts and big events: the  TTL33-A

Based in Rancagua, in central Chile, Juan Francisco Aguilera’s CYS Audio Profesional has been providing advanced RCF solutions, notably for prominent Latin American Christian singers, for the past 13 years. He has turned every time to RCF’s advanced TTL33-A active line array system as his preferred solution.
One such event in his native city was the recital by Christian musician Daniel Calveti in the Estadio El Teniente. Some 6,000 fans were treated to a concert played back through the TTL33-A system, designed by CYS Audio around two PA hangs of nine TTL33-A line array elements, with six floor-mounted ESW 1018 18in subs on each wing.
Another notable Christian music performance was by Costa Rican Danilo Montero, when 7,000 fans arrived in the city of Talca. Juan Aguilera this time provided coverage from seven TTL33-A enclosures each side with ART Series monitors providing front fills.
And in September there will be a further star of this genre appearing in Chile when Marcos Barrientos performs in Copiapó.
Along the way he has also provided coverage for the anniversary of the city in which he is based, when 15,000 people flooded onto the streets of Rancagua to hear Chilean artistes such as Andres de Leon and Grupo la Noche. He fielded 24 x TTL33-A enclosures — divided into two hands of nine elements for the main PA, with a further six modules forming the delay. He then turned to six ART Series speakers to provide front fills.
The TTL-33A’s flexibility makes it the perfect solution for events such as this — both indoors and out. Compact, with wide dispersion, this 3-way active line array offers incredibly high output and dynamics, extreme accuracy and high frequency extension.
RCF have recently provided the audio system for the Palazzina di Caccia (hunting lodge) of Stupinigi, one of the residences of the Royal House of Savoy, which was built by architect Filippo Juvarra in 1731. This out standing palace, located in the little town of Stupinigi near Turin, has been awarded World Heritage List by Unesco.
The project has been designed by the RCF Project Design Office, on the based on the original design made by Mr. Sergio Berno from the EL Engineering Service of Turin. The installation has been completed by Orion Gesta under the supervision of engineer Ivan Catellani.
The main audio system is the RX4000, a completely integrated system for voice evacuation, paging and background music and is EN 60849 CEI 100-55 compliant. The main control unit manages two more units, located in other parts of the building and are connected to the first through CAT 5e UTP cable. All three units are equipped with boards for the diagnostic of the amplifiers, and the speaker line (ground, short circuit, ect.) and microphone consoles.
The two slave units are also equipped with EOL boards to check the connection with the main central unit. Three different banks of recorded messages are controlled by the central unit.
The audio system has been divided into 11 zones, managed entirely by the main unit, CP4100, that process’s and sends all the standard paging an emergency calls that come directly from the fire alarm system.
The microphone consoles are a BM 4716 with an LCD display to control the system, that manages the announcements and the background music for all the 11 zones, and a fireman’s paging console, EN60849 compliant and that has the highest priority.
For the big oval shaped manor hall, which represents the core of the whole palace, DP1T/G sound projectors have been installed, that, thanks to their directivity and high audio quality, have proved the best choice for big reverberating spaces. Thanks to their compact size, high quality, controlled dispersion and very good frequency response in vocal reproduction, MQ80P have also been installed in the main hall.
To amplify the sound in the 4 corridors that start from the main hall, DU100X have been used. The compact sized DU100X are highly efficient speakers, with an outstanding versatility when used in this type installation procedure. To minimize the visual impact of the speakers in such an historic palace, the Orion Gesta installers have hidden them inside fireplaces or niches in order to preserve the integrity of the richly painted a fresco walls. Even MQ80P speakers have been camouflaged thanks to the niches in the balconies.
Thanks to this configuration the RCF system has allowed a uniform sound dispersion in the whole palace, with the advantage of just one main control unit that manage all the system simplifying the operations.
The Kameha Grand Hotel in Bonn is a five star hotel where the architecture is more refined, the design are trendsetting, and it´s hotel structure that has become the new 'Lieblingsplatz' directly located to the river Rhine. The Kameha Grand Bonn is about ecological lifestyle and design hotel and the location gives a wonderful view of the Siebengebirge Mountains.
This newly built property redefines service and offers colour, warmth and atmosphere, and it is equipped with luxurious furnishings and cutting-edge technology.
In the Terrace Bar there have been installed 22 pcs of RCF MQ80P-S speakers. The MQ80P-S model is IP55 and very suitable for outdoor use. These are installed in different combinations: Single, twin and triple clusters. The speakers are installed on stainless steel columns and are covering the whole Terrace Bar area.
The company “Kuchem Konferenz Technik” from Königswinter realized the installation in co-operation with RCF Germany that supplied technical documentation, EASE simulations of the project etc. The construction designers of the Terrace Bar decided the placement of the stainless steel colums. So the EASE simulations was an important tool to secure that the installation of the speakers was set in the right angles to cover the whole area of the Terrace Bar and to get a perfect result.
Terrace Bar has a smooth and equal audio level (about 90% of the area are in between 97dB SPL +/- 3dB) and the 22 speakers fit perfectly the high-class environment of the Kameha Grand Hotel.
The Holy Spirit complex in Porto Torres (Sassari) incorporates a church, several multi-purpose halls and a sports area on a total surface of over 8000 sqm. The complex was constructed in 2016 as an important point of reference for the local community, at a total cost of of 2 million euros.
A critical factor for the choice of sound reinforcement products was the architectural structure of the church: it is an open space, 36 m wide and 16.5 m deep, excluding the choir and chapel. There are no installation points, and the perimeter walls are the only anchor points available.
Two RCF VSA2050 columns have been installed on the side walls, plus one VSA1250 near the altar, to reinforce the front rows. Such a small number of products allows the integral coverage of the large space with its 36 m width, thanks to the VSA columns’ deep throw and 130° horizontal coverage.
VSA speakers are ideal for installation in acoustically challenging ambient spaces or in areas where particular architectural constraints exist.
A simple control mechanism allows the audio signal to be directed towards the listening area and avoids the dispersion of acoustic energy towards the ceiling or into empty zones; this ensures the removal of echoes and other effects that might compromise intelligibility.
Thanks to the compact size and low profile, the speakers have a discreet appearance that easily blends into the building’s interior design. The VSA speakers installed in the Holy Spirit church have been painted with the standard color, but RCF can supply speakers with personalized RAL tints, in order to minimize the aesthetic impact in any venue.
A second VSA1250 column is dedicated to the monitoring of the choir, and this is situated next to the altar. A two-way compact DM 41 speaker has been installed in the sacristy for monitoring purposes, and the small closed chapel next to the altar, measuring 7 x 6 metres, has been reinforced with a two-way slim-line CS3082 column speaker and the AM 1064 amplifier-mixer (60 W with three audio inputs).
The external part of the church is a vast yard without a porch, and for this area the P2110-T coaxial two-way speakers – with perforated aluminum front grille and water-repellent fabric backing – were chosen and installed on the external walls. These speakers meet the requirements of the IP 55 code against the ingress of liquids, solids and external agents. “We chose the P Series speakers because they are horn-loaded, so they guarantee efficiency and high directivity in an area as large as the external yard. They are also weatherproof,” say RCF engineers that where involved in the project.
The Sassari-based Costec company was encharged of the installation of the sound reinforcement system in the church of the Holy Spirit. The chairman Mr. Tonino Loi, has worked previously with RCF on delivering other notable projects on the island, including the fire-alarm system for the Brotzu hospital in the city of Cagliari in 2007. He reports that the installation and launch phases in Porto Torres were carried out rapidly and the customer was highly satisfied with the final results.
The church was inaugurated in June 2016, realizing a dream that the local community had for several decades. Around 1500 people participated in the dedication of the building.
