ARCS II SYSTEM
The ARCS
®
II (Arrayable Radial Coherent System, generation II) has benefited from a design exploiting the Wavefront
Sculpture Technology
®
in a constant curvature line source solution. Intended for the medium to large rental productions,
it delivers remarkable power, bandwidth and coherence, along with a flexible and predictable coverage. Besides, it offers
the audience an incomparable listening experience featuring clarity, precision and impact.
The main system components are as follows:
•
ARCS
®
II, full-range element, operating from 50 Hz to 20 kHz;
•
SB28, low-frequency element, operating down to 25 Hz;
•
LA-RAK, touring rack fitted with three LA8 amplified controllers;
•
LA4X amplified controller
The ARCS
®
II enclosure offers a number of improvements over the previous generation, the major of them being the K1
grade transducers for more resources and lower weight. It also features a new front grill for enhanced durability and
cosmetics, and is driven by a single factory preset to accommodate any applications efficiently.
An ARCS
®
II line source can be deployed either horizontally or vertically, with a coverage angle that is 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 the asymmetric distribution, allowing the use of a horizontal ARCS
®
II line source either for upward or
downward coverage.
The ARCS
®
II can be quickly deployed as a tightly-packed front of house 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, center cluster for theatrical work, sidefill monitoring, flown or stacked center fill, stereo front
fill, offstage fill or delay system for concert audiences in stadia and arenas. Before installation, any system configuration
can be acoustically and mechanically modeled with the SOUNDVISION 3D simulation software.
As a distribution platform for power, audio signals and network, the LA-RAK touring rack fitted with three LA8 amplified
controllers is the heart of the system. Thanks to dedicated factory presets, it constitutes an extremely advanced and
precise drive system for the enclosures. In high-end installation projects, the LA4X amplified controller can deliver
maximum power headroom and the best possible performances. All L-ACOUSTICS amplified controllers feature the L-
DRIVE, a thermal and over-excursion protection circuit.
Up to 253 amplified controllers can be connected together via the Ethernet-based L-NET protocol. The LA NETWORK
MANAGER software allows online remote control and monitoring of all the connected units, via a user-friendly and
intuitive graphic interface, and features the Array Morphing EQ. This exclusive tool allows the engineer to quickly adjust
the tonal balance of the system to reach a reference curve or to ensure consistency of the sonic signature.
