OTK reports that the existing sound rig badly needed upgrading, since the oldest of the original systems had been installed 14 years before, and was beyond repair. It also lacked clarity - and sufficient SPL to provide even coverage across the 1000-capacity space. Furthermore, other design features (such as a 'wrecked ship') had been added, while the peripheral and service areas had also been expanded.
The operators wanted to achieve an even dispersion right to the outermost seats in the wide arc, with a consistent SPL that didn't deviate off axis.
A QSC solution was recommended as being the most cost-effective, and since the ILA provides an impressive 140° horizontal coverage this would eliminate the need for out-fills or a centre cluster - further minimizing costs.
OTK decided to install six WL2082-i loudspeakers and a pair of WL118-sw subwoofers, after modelling the vertical directivity using QSC's simulation software. A dedicated SC28 system controller optimizes the performance. The speakers are driven four-way (three-way plus subs) by a combination of QSC PowerLight PL325 and PL340 amplifiers.
The speakers have been installed discreetly within the themed backdrop of the performance area - one at the base of the wrecked ship's mast (on the right side), the other inside the artificial rock (on the left). Each of the six line array elements are mounted 5m from the ground with the two subwoofers stacked alongside.
