AdLib Audio Hires of Liverpool, UK provided sound reinforcement services for a series of live music events that took place September 15, 16 and 17 in London’s Trafalgar Square. The company installed a complete, large-scale audio system featuring JBL Professional VerTec line arrays and Soundcraft’s new Vi6 digital mixing console.

AdLib Audio provided two main left/right arrangements of VerTec VT4889 full-size line array elements, with additional outfill arrays positioned to serve the large audiences in the broad public square. A total of 38 VT4889's were used, along with eight midsize VT4888's for front-fill coverage. The Soundcraft Vi6 digital mixing console was manned by AdLib company principal Dave Kay as front-of-house mixer for the Scissor Sisters' performance.

"We served three different types of events in a row with the same stage and setup,” says Tony Szabo, primary system engineer for AdLib at the events. "The shows varied in crowd size and program content, but AdLib needed to ensure that, as the concert sound supplier for Scissor Sisters, the high level of production values normally provided on tour were online for the public event at Trafalgar Square.

"JBL's VerTec system worked very well in this application," notes Szabo. "The rig's light weight is a distinct advantage in tower-based structures like we have on-site. And with the London Council's ever-growing concerns about sound limits and neighborhood environmental noise issues, we had to work within the constraints of specific health and safety issues.”
