KWANGJU, South Korea —Systems integrator Sovico AV recently installed a new JBL VerTec powered full-size line array system at the new Kwangju CD nightclub, the largest dance music and DJ venue in South Korea.
With over 36,000 square feet, as many as 300 tables and 30 private rooms, the Kwangju CD venue also has an octagon-shaped overhead ceiling that is divided into separate moveable parts, enabling it to mechanically open to support a variety of special effects including artificial snow and fancy lighting.
“The design of the facility, with such an extensive hall size, required a powerful system to support the variety of performance activities taking place in this space,” said sound designer Jon Won Lee. “The sound system in the club must serve five specialized DJ teams, two different house bands, three dance teams and two performance art teams.”
Along with special multimedia programming to support performance artists, Lee needed to make sure the Live DJs and late-night dance music playback could co-exist with live house bands on stage and provide even coverage and high SPL for the building’s unusual layout.
To meet the sound design specifications, Sovico installed a total of 12 VerTec VT4889ADP powered full-size line array elements, configured in two arrays of six. These arrays are supported by eight VT4880ADP powered full-size arrayable subwoofers with 2269H 18-inch transducers, configured in two arrays of four each, located in coves beneath the performance stage. The main system makes use of JBL DrivePack technology, which incorporates Crown Audio’s BCA (Balanced Current Amplification) and Class I circuitry.
Four JBL PRX535 powered systems are also being used as localized area fill speakers. Sound engineer Jung Hyun Park can use signal processing that includes 2231 dual 31-band graphic equalizers and 1066 dual compressor limiter gates from dbx, and a Lexicon MXP1 effects processor.
A Soundcraft GB8 is the primary mixing console for the venue. Seven AKG WMS4000 wireless microphone systems are on hand for use by performers. Upon system commissioning, Sovico engineers conducted comprehensive onsite training sessions for the venue’s technical staff.
“The new powered full-size models in the VERTEC family make an ideal system design approach for this type of application,” said David Scheirman, vice president, tour sound for JBL Professional. “The models selected for the Kwangju CD club offer high output power capabilities combined with complete system integration including the onboard digital signal processing inherent to the JBL DrivePack technology platform.”
Sovico AV installed the system with design assistance from Sovico R&D, the firm’s acoustic research laboratory specializing in acoustic measurement, sound design and system tuning.
