Ankara, Turkey (October 12, 2015)—The Turkish Parliament building in Ankara is a formidable place, and its fan-shaped debating chamber can hold 500 Parliamentarians. In order to help facilitate debate by localizing sound in order to ensure everyone could tell who was speaking, regional audio provider Atempo brought in Dr. Wolfgang Ahnert—the inventor of EASE software—to rethink the auditorium’s audio system.
Put to open tender, Atempo presented a system using a mix of d&b audiotechnik loudspeaker systems. “In essence, this is a two-system solution: There is a front-facing system of left/right d&b Ti10Ls so that the platform can address the whole house. The second system is distributed, a set of ceiling clusters, using individually amplified d&b 10S loudspeakers arranged to face downward and in a cross formation to give 360-degree propagation. The key to this system is the Salzbrenner Stagetec Nexus matrix system management that, through programmed time settings, can localize sound to the region of any Parliament member who is talking, relative to the rest of the chamber. Naturally that’s quite a complex and variable timing structure for such a broad coverage area, so selection of the correct loudspeakers and their consistency of performance, particularly in terms of pattern definition, was crucial.”
Parliament normally goes into recess for three months across the summer but the year of installation coincided with the presidential elections, “Which cut install time in half to just six weeks,” said Tayfun Konuralp of Atempo. “We worked almost around the clock, assembling three teams working six to seven hour shifts. Fortunately we have strength and depth in our audio teams so all three were in house staff. Even so that’s a big commitment of resources and we needed every minute of those six weeks.
