L-Acoustics' ARCS II, geared for medium-to-large rental productions, features Wavefront Sculpture Technology (WST) in a constant curvature line source solution, promising power, bandwidth, coherence and flexible/predictable coverage.
The bi-amplified ARCS II enclosure is based on a two-way active design and offers a number of improvements over the previous generation, primarily L-Acoustics' K1 grade transducers for increased SPL (140 dB) and lower weight (110 lbs / 50 kg). It also features a new front grille 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 effective stereo imaging. The ARCS II is also well-suited for use as a distributed system, center cluster for theatrical work, sidefill monitoring, flown or stacked center fill, stereo front fill, offstage fill or delay system for concert audiences in stadiums and arenas.
Users of ARCS II can benefit from the LA-RAK touring rack and LA8 amplified controller preset library, L-DRIVE intelligent two-way transducer protection circuit (PEAK and RMS limiting) and Array Morphing EQ interface, which is designed to let the engineer quickly adjust the tonal balance of the system to produce a reference curve, helping to ensure consistency of the system's sonic signature with multiple arrays of different types and sizes.
ARCS II is scheduled to ship in October 2011.
