L-Acoustics adds flexibility to Atlanta centre
- Details
A venue this flexible needed a sound system equal to the task. It found one in the A15i loudspeaker from L-Acoustics, 42 of which use both Wide and Focus enclosures to guarantee precise coverage at every seat - comprising a sound system configurable for any occasion. System design and specification were performed by Idibri, a Salas O’Brien Company, while the system installation and integration was accomplished by Athens, GA-based Technical Services Audio Visual (TSAV).
“It’s essentially one sound system that can operate as two separate sound systems,” explains Ben Boeshans, senior consultant at Idibri. “There are clusters over the stage, court, and seating areas, and each are programmed to either fire or mute, depending upon the application. We designed in a QSC Q-SYS Core 510i as the control system, and the configurations and switching are programmed using the L-Acoustics Q-SYS plug-in, which offers streamlined native control of the amplified controllers and loudspeakers. The entire system can be reset as needed at the push of a button.”
The 42 A Series loudspeakers are deployed in hangs designed for either “event” or “sports” modes. The former comprises two main forward-firing arrays of four enclosures each over the stage, buttressed by two three-enclosure side-fill arrays. Coverage to the seats furthest from the stage is accomplished with five delayed arrays.
In the “sports” mode, those delay speakers become five of the eight main arrays covering the seats for basketball. These are either two- , three-, or four-box arrays, depending upon the configurations of the seating areas they need to cover.
In addition, there are four KS28 subwoofers hung over the centre court as two hangs in a dipole configuration. The subwoofer design, says Boeshans, directs the sound to create an ellipse that more uniformly covers the seating areas. In total, a dozen amplified controllers power this remarkably flexible system: 11 LA4X and one LA12X.
