For the concert's live TV and radio simulcast, as well as a live audience of 13,000, Regensdorf, Switzerland-based Habegger AG met the challenge with a robust system of Meyer Sound self-powered loudspeakers, provided by Hamburg, Germany-based Procon Multimedia AG.
System design was handled using Meyer Sound's MAPP Online Pro acoustical prediction programme. "The Hallenstadion is highly reflective, especially in the rear," says FOH sound mixer Dani Niedermann. "But we managed to design a great-sounding array with no reflection whatsoever. I didn't think a simulation could be that accurate, but MAPP's predictions turned out to be right on."
The final configuration included two arrays of 11 Milo line array loudspeakers and one Milo 120. Ample low end was provided using an end-fired arrangement of two groundstacked clusters of three 700-HP subwoofers per side, and another two 700-HPs per side placed on a catwalk some 65ft (20m) from the stage. A single Galileo loudspeaker management system provided system drive and processing.
