Vicente Calderón Stadium
The Vicente Calderón Stadium in Madrid equipped with D.A.S. Audio systems
|The Vicente Calderón stadium in Madrid has recently been outfitted with D.A.S. Audio professional sound systems. Home to the Club Atlético de Madrid, the stadium has hosted the team’s games since it opened its doors in 1966. With approximately 55,000 spectators packing the stands for these events the stadium needed a powerful yet precise system and the D.A.S. Audio systems distributed around the venue more than fit the bill, providing crystal-clear sound for fans in the Calderón’s four main stands.
Not only were the D.A.S. Audio technicians unable to hang the sound system in this open-air stadium but they were further were restricted by UEFA regulations on the maximum height of the billboards, behind which the systems would have to be located. After studying the venue’s particular characteristics the team recommended deploying the powerful new Aero 40A ALAS™ (Advanced Line Array System) powered systems. The team rolled out 28 of these systems in total, convinced that the Aero 40As’ reliability, power and clarity would provide top-of-the-line sound pressure and coverage.
After deciding which systems to use the technicians had to rig and distribute the line arrays under UEFA’s height regulations. D.A.S. Audio came up with an innovative solution and custom designed 14 mobile platforms, mounting a pair of Aero 40A systems on each. The special feature of these platforms was the systems’ degree of angulation; the starting angle had to be quite large since each platform only had two units. Thus, the lower system “points” to the lower tier of the stand while the higher system targets the upper tier.
The 14 platforms mounted with two Aero 40As each were distributed to cover the stadium’s four main areas. Three platforms provide the sound for the Preferred Side, the covered stands on one side of the field; five cover the opposite Lateral Side; three are directed at the North side of the stands and another three handle the South Side. Each of the 14 platforms boasts robust covers that were specifically designed to protect the systems from inclement weather. Custom-made, the systems can be used without removing these covers; they are simply folded back over the top of the mounted systems.
Each of the four zones (lateral and ends) features a DASnet™ rack to remotely control and manage the systems. Each rack includes a D.A.S. DSP-2060A digital signal processor for managing the audio signal, a patch panel for the audio and data signals that connect the racks, a DASnet™ panel to receive and carry signals, data and power to the Aero 40A systems and a three-way 32A power distro with six single-phase 16A outputs to connect to the main power supply.
The ingenious mounting solution with the D.A.S. Aero 40A systems that the sound team designed for the iconic Vicente Calderón stadium is an effective and interesting alternative for venues where a flown system cannot be rigged. This set-up gives all the features of the D.A.S. Aero 40As a chance to shine, as evidenced during the recent Champions League quarter-final clash between Club Atlético de Madrid and FC Barcelona, when the systems were put through their paces and provided superb sound for the fans that packed the stands.
