One of Europe's top football stadiums, the Estádio da Luz in Lisbon, Portugal, has been equipped with a new Electro-Voice and Dynacord sound system.
Home to S.L.Benfica, with a capacity of 66,000, the 'Stadium of Light' was outfitted with Electro-Voice EVH and EVID loudspeakers divided into 48 individually controlled zones, as well as DSA power amplifiers and a P 64 digital audio matrix manager from Dynacord. Installation contractors Meißner commissioned Hesse + Partner to plan the installation.
A total of 108 coaxial, horn-loaded EVH loudspeakers flown from the stadium roof are designed to provide homogeneous coverage of the stands and playing area. The specification of these loudspeakers was no simple affair, as Hesse explained: “As the distance from the roof to the rows below is never constant, each loudspeaker was chosen according to its individual installation position.”
Fortunately the EV Innovation series, with its variety of dispersion patterns, allowed a differentiated yet coherent system design based on components of similar type.
Complementing these are 378 transformer versions of EVID loudspeakers, designed to deliver optimal sound on the slightly recessed balcony tiers thanks to their even dispersion and compact dimensions. The power for all the loudspeakers is provided by 42 DSA multi-channel power amplifiers equipped with RCM-810 remote control modules.
A key role in the sound reinforcement design is played by the P 64 digital audio matrix manager, which is controlled using IRIS-Net software. The individually configurable user interface of IRIS-Net allows the channel-based individual configuration of the output (Variable Load Drive) of the multi-channel power amplifiers. It also provides full control and supervision of all the power amplifier channels and loudspeakers.
“The support we received from the Dynacord team here and in other areas was really tremendous,” concluded Hesse. “The sound in the stadium is truly magnificent. Some of my colleagues are even of the view that in terms of sound quality this is one of the finest stadiums in the entire world. And I think they are right.”
