JBL VTX Line Arrays Power Emporium Music Festival

    Netherlands-based production company Story Sound BV recently deployed its new HARMAN’s JBL VTX line array system at the Emporium dance festival in the Dutch city of Nijmegen. The Festival, which this year drew 30,000 people (and 120 DJ’s), embraces every genre of dance music from trance/progressive to hardstyle.

    For the festival, Story Sound deployed almost 350 JBL loudspeakers, including 138 of the new VTX V25 full-range enclosures, powered by 190 Crown I-Tech HD amplifiers. The main stage also had two delay points, each containing six more VTX arrays, while the VIP section of the tribunes featured two further delay points, each containing six JBL VERTEC® VT4887A compact line array elements.

    The stage sizes then reduced from area to area, with the smallest containing five V25 loudspeakers per side.

    Taking into account three wind directions, Story Sound installed a wireless measuring device to monitor the sound levels (which were restricted to 85dBA at 100 meters), set 100 meters behind three of the stages. “Since VTX is highly focused and offers us more controllability we could produce a higher overall sound level for the audience,” he explained.

    Story Sound provided a sound technician to supervise each stage, with wireless laptop communication back to the central network control position in the production village, overseen on the HARMAN HiQnet™ platform by Story Sound’s Barney Broomer. “We could listen to the measuring microphone on the same network while we also had a range of Soundcraft desks—Vi6, Vi4, Vi1, Si Compacts on the smaller stages—so we could control the input of the DJ and monitor feeds, as well as the MCs’ microphones, using the dynamics of the desk,” said Story.

    Each DJ was provided with two JBL VRX932 loudspeakers per side as high-class reference monitoring so they were not mistaken in thinking that the lack of sound bleeding back onto the stage was an indicator that their levels were too low.
