Daegu Stadium has hosted major sporting events including the World Cup, and will be the site of the 2011 IAAF (International Association of Athletics Foundations) World Championships in Athletics. To prepare for the IAAF and other future events, the city of Daegu decided to upgrade the stadium's audio facilities, which now includes a large-scale JBL Variable Line Array (VLA) Series loudspeaker installation with 18 line arrays in distributed clusters.
The sound system was designed by Wrightson, Johnson, Haddon and Williams (WJHW) of Dallas, Texas, and the installation was performed by Sovico Corporation of Seoul, South Korea.
The Daegu system employs JBL VLA901 and VLA601 line arrays. The VLA Series loudspeakers were chosen because of their ability to provide high-impact sound reinforcement at throw distances beyond the reach of traditional speaker designs. In Daegu Stadium, the distances between the seats and the speakers can be more than 160 feet. The VLA901 and VLA601 speakers are suspended above and in front of the seats from beams that are part of the roof's support structure. Eighteen distributed clusters of VLA901 and VLA601 loudspeakers are located throughout the stadium, to cover the seating areas and other locations where sound reinforcement is required.
JBL VLA Series loudspeakers are specifically designed for permanent installation applications where even coverage, high intelligibility and very high sound-pressure levels are required. The VLA Series offers a modular approach that gives system designers the ability to build large line array systems for bigger venues, or design smaller line array systems for use as distributed clusters in arenas and domed stadiums, and larger performance spaces and houses of worship.
