The worldwide retailer presentation of the “Audi Q5” took place in September of 2008 in Lisbon, Portugal. Centrepiece of the exhibition was a multimedia-based show performed at the Pavilhão Atlantico a multipurpose arena built for the Expo ’98. The main PA system was built of five line arrays and a horizontal bass array in a 5.1 surround setup, apart from numerous delay lines and monitor speakers. My job consisted of commissioning and tuning the sound system for the show. After an initial check of the systems components various acoustic meaurements were realized that form the basis for the EQ and delay setting.
