L-Acoustics launches constant curvature line source

AUTHOR: Inavate

L-Acoustics has employed Wavefront Sculpture Technology in its ARCS II constant curvature line source.

It is aimed at medium to large rental productions.

The bi-amplified ARCS II enclosure is based on a two-way active design. It offers L-Acoustics’ K1 grade transducers for increased SPL (140 dB) and a weight of 50kg. It features a new front grill and is driven by a single factory preset to efficiently accommodate any application.

An ARCS II line source can be deployed either horizontally or vertically, with a coverage angle proportional to the number of enclosures in the array (N x 22.5°). On the other plane, vertical or horizontal respectively, the ARCS II line source provides an asymmetrical coverage angle of 60° (20°/40°). The orientation of the ARCS II enclosures within the array determines asymmetric distribution, allowing the use of a horizontal ARCS II line source either for upward or downward coverage.

ARCS II can be quickly deployed as a tightly packed FOH system for medium throw applications with high SPL, LF impact and excellent stereo imaging. Other applications include distributed system, centre cluster for theatrical work, sidefill monitoring, flown or stacked centre fill, stereo front fill, offstage fill or delay system for concert audiences in stadiums and arenas.

The LA-RAK touring rack and the LA8 amplified controller preset library deliver an extremely advanced and precise drive system for ARCS II. Additional features include the L-DRIVE intelligent two-way transducer protection circuit (PEAK and RMS limiting) and an Array Morphing EQ interface.
