Overview<\/span><\/h3>\n

[\/vc_column_text][vc_column_text]The Caja M\u00e1gica<\/a> is one of the most innovative multidisciplinary buildings in the world<\/strong>. The venue is home to the tennis Mutua Madrid Open<\/a> every year since 2009 and hosts several sporting events (Davis Cup, Handball World Championships, European Volleyball League, international basketball games, World Padel Tour, World Judo, and other world championships), business events, musical events (MTV Awards, Mad Cool, Download, and mass concerts) and film shoots for adverts, film and TV.<\/p>\n

Built in steel, wood and glass, the complex was designed by French architect Dominique Perrault.<\/p>\n

The name \u201cCaja M\u00e1gica\u201d refers to the stadiums’ enclosure, which gives them a dynamic and changing appearance.<\/p>\n

The Caja M\u00e1gica has three clay courts with movable roofs. The Manolo Santana Centre Court has a capacity of 12,500 spectators. Courts 2 and 3 have 3,500 and 2,500 seats, respectively.<\/p>\n

It is a large venue with an important flow of visitors<\/strong>. There are different sound zones and each of them needs to be controlled individually and coordinated with the others.<\/p>\n

The Caja M\u00e1gica\u2019s public address and voice alarm system<\/strong> was originally installed by system integrator Ruybesa<\/a> in 2008 using LDA equipment and Bose<\/a> loudspeakers.<\/p>\n

In 2021, the Caja M\u00e1gica requested a renewal of the system and the team Ruybesa \u2013 LDA was again awarded in a public tender to undertake this job.[\/vc_column_text][vc_empty_space height=”30px”]

Challenge<\/span><\/h3>\n

[\/vc_column_text][vc_column_text]The goal was to implement a robust state-of-the-art PA\/VA multi-site system with no single point of failure (SPOF)<\/strong> to operate in the whole venue.<\/p>\n

To ensure the non-existence of a SPOF in a system, all its components had to be usually redundant<\/strong>, creating a high availability system, which guarantees correct operation even in the case of failure of any of its components.<\/p>\n

Caja M\u00e1gica required to maintain all the advanced functions of its public address system and to upgrade them with new generation systems<\/strong> incorporating the latest state-of-the-art technology<\/strong>.<\/p>\n

In addition to the central requirement, i.e. a redundant “no single point of failure” solution, the system interfaces had to be improved<\/strong> by including installation drawings and equipment display on them.<\/p>\n

The new system had to be integrated with the use of existing Bose processors for PA sound in the stadiums, which use Bose loudspeaker boxes. This way, the PA-BGM (public address) and VA (evacuation) operations would be managed under the same unified system<\/strong>.<\/p>\n

The project’s requirements involved the simultaneous management of 5 public address and voice evacuation areas<\/strong>: 3 for the stadiums, with duplicated and redundant control systems, and another 2 for the circulation area (outside the Caja M\u00e1gica) and for the Tenis Indoor annex building.<\/p>\n

The control systems of the 3 stadiums were to be duplicated, but not the amplifier units, so that there would be automatic switching in their operation and the service would not be affected at any time despite a possible failure<\/strong>.[\/vc_column_text][vc_column_text css=”.vc_custom_1681387033619{margin-top: 20px !important;margin-bottom: 20px !important;padding-top: 10px !important;padding-right: 20px !important;padding-bottom: 10px !important;padding-left: 20px !important;background-color: #f0163a !important;}”]<\/p>\n

Solution<\/span><\/h3>\n

[\/vc_column_text][vc_column_text]The system has been designed to support the matrix flow of audio signals between sources and destinations<\/strong> to provide high-quality audio in each zone.<\/p>\n

By using a multi-tasking panel and the user-friendly LDA SIME software<\/a>, it allows the operator to route or direct the message coming from either the microphones or the players in the required area.<\/p>\n

The complete system consists of two partially centralised LDA subsystems<\/strong>, each of which is in a separate rack placed in different locations around the venue.<\/p>\n

For the Caja M\u00e1gica, LDA Audio Tech has designed an architecture with no single point of failure<\/strong>.<\/p>\n

It is a multi-site system<\/strong> with:<\/p>\n
