Last week’s InfoComm 2012 show in Las Vegas saw L-Acoustics debut its new ARCS Wide and ARCS Focus systems.
Based on two constant curvature enclosures holding distinct directivity pattern and SPL capabilities, the new systems are intended for use in medium-throw applications in rental productions and fixed installations. The line source systems are designed to provide optimum versatility and performance across a host of applciations, including FOH L/R systems, central clusters, side-fill monitors, distributed systems and complementary fills.
The main systems components consist of the following:
• ARCS® WIDE (H x V: 30° x 90°) element, wide coverage
• ARCS® FOCUS (H x V: 15° x 90°) element, focused energy
• SB18m low frequency extension, operating down to 32 Hz
• LA4 or LA8 amplified controllers
Both the ARCS Wide and ARCS Focus line sources are aimed at delivering high SPL with optimised acoustic coupling, solid LF performance and constant tonal balance over distance. Each system can be deployed as either a horizontal or vertical array.
In the coupling plane, both systems are built to offer a precise directivity pattern; especially valuable to sector audience fields, while avoiding reflective surfaces. In the other plane, both systems provide a 90° symmetric directivity pattern.
The ARCS Wide is designed to achieve extensive coverage with few elements, offering a compact array that preserves sightlines. 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°.
The ARCS Focus line source focuses the same acoustic energy within half of the coverage angle, i.e. N x 15°; achieving a narrower coverage and offering a higher SPL with a more extended throw than its counterpart.
The ARCS Wide and ARCS Focus can also be deployed in “WIFO” hybrid arrays for complex audience geometries.
L-Acoustics marketing director Stéphane Ecalle, explained: “Offering scalable coverage from 15 or 30 degrees to a full 360, ARCS Wide and ARCS Focus are truly ‘plug and play’ systems suitable as mains or fills for most events. Couple that with L-Acoustics’ reputation and rider acceptance, as well as the convenience of cross-renting product with Network Agents, and we believe that these two new systems will prove themselves to be solid, enduring investments with high ROI and long-term resale value for our rental users.
“For installations, the systems’ coverage can be tailored to fit optimized installation budgets, and the dual directivity pattern can provide effective solutions for challenging room acoustics.
“With tightly-packed arrays, the system tidily preserves sightlines and is architecturally friendly, offering an IP 45 protection rating for outdoor installations.
“Sound designers and engineers will undoubtedly appreciate the familiar sonic signature, predictable coverage pattern, intuitive rigging, and single preset approach for both cabinets.
“But the bottom line is the investment effort. With ARCS Wide and ARCS Focus, we are offering kits that are extremely evolutive in both performance and pricing. So in addition to delighting our existing client base, many others will now finally be able to make the L-Acoustics dream a reality.”
