The ARCS II benefits from a design exploiting L-Acoustics' Wavefront Sculpture Technology in a constant curvature line source solution. Intended for medium to large rental productions, it delivers remarkable power, bandwidth and coherence, along with flexible and predictable coverage. It also offers the audience an incomparable listening experience featuring clarity, precision and impact, says the company.
The bi-amplified ARCS II enclosure is based on a two-way active design. It offers a number of improvements over the previous generation, primarily L-Acostics' K1 grade transducers for increased SPL (140 dB) and lower weight (50kg). It also features a new front grill for enhanced durability and appearance, 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. Thanks to its precise and flexible coverage capability, 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 stadia and arenas.
