L-Acoustics ARCS WIDE and ARCS FOCUS constant curvature WST line source systems are designed for medium-throw applications in rental productions and fixed installations. These line sources deliver acoustic properties for church installations, including front-of-house, L/R systems for live music reproduction and central clusters dedicated to speech reinforcement.
The ARCS WIDE or ARCS FOCUS line sources provide high SPL with quality acoustic coupling, a solid LF performance, and constant tonal balance over distance. Each system can be deployed as a horizontal array or as a vertical array. In the coupling plane, the ARCS WIDE and ARCS FOCUS yield a sharp directivity pattern, particularly valuable to sector audience fields. In the other plane, both systems provide a 90-degree smooth symmetric directivity pattern.
The ARCS WIDE is suited to achieve extensive coverage with few elements. The total coverage angle of an ARCS WIDE line source is proportional to the number N of enclosures in the array (i.e., N x 30 degrees). The ARCS FOCUS line source focuses the same acoustic energy within half of the coverage angle (i.e. N x 15 degrees).
The ARCS WIDE and ARCS FOCUS can also be deployed in "WIFO" hybrid arrays for complex audience geometries. The dual directivity pattern and the various system configurations offer flexibility. Before installation, all these configurations can be acoustically and mechanically Lmodeled with the SOUNDVISION 3D simulation software.
