Singapore’s mammoth ZoukOut Festival returned to the city’s Siloso Beach in December, treating more than 30,000 revellers to DJ sets from some of the world’s superstar DJs. Nestled between the water, a nature reserve and high-end hotel resorts, the festival’s sound needed to be full frequency, highquality, and directed only to the ears of attendees. To achieve this, a d&b audiotechnik GSL system was used, in conjunction with d&b ArrayCalc and NoizCalc software.
