Choosing a PA system to be installed at the Oper Frankfurt (Frankfurt Opera House) involved a great deal of time, care and painstaking accuracy, according to head of the live sound and CD production team Peter Tobiasch. A d&b system ended up fitting the tight area to a ‘T’. “Two centimetres more of dimensions would have stopped the project, and this was the only mid-sized line array system with the required quality level which could fit at all,” he
commented. “When we came to bring in a new d&b audiotechnik PA system behind the panels that flank the proscenium, the view from the audience had to remain totally unaltered.” The opera house’s new system – installed by Nies electronic GmbH – comprises d&b T10 loudspeakers behind the panels, with T-SUB and B4-SUB arrays below, and required modifications to the standard T-Series mounts to fit in the small space, as well as adhere to engineering regulations.
Despite the technical challenges,
Tobiasch reported “no hearable interference and phasing, no frequency peaks and dips. It is for
me the most important quality aspect that the d&b loudspeakers do not make ‘sound’ on their own; you just hear voices and
Tannoy’s digital beam steering QFlex loudspeakers have been installed by Audio Light Systems at Edinburgh’s historic Royal Commonwealth pool as part of a £37 million (€44 million) renovation project. Steve Aitchison, project engineer for Audio Light Systems, said: “The original design put forward was for a series of large speakers pointing downwards. But this type of system design was what they had there before, and it caused some problems with intelligibility due to the reflective nature of the space.”
The solution was two QFlex 48s close coupled facing 90˚ from each other, mounted 6m high. Just two units are able to provide total coverage of the pool area. “The intuitive BeamEngine GUI allows the designer to specify target areas. It meant we were able to visualise the coverage of each loudspeaker in the system and create steering files to suit the specific space,” Aitchison said. www.audiolightsystems.comwww.tannoy.comwww.thecommiepool.co.uk
