The ARCS® WIDE and ARCS® FOCUS systems are based on two constant curvature enclosures ensuring distinct directivity pattern and SPL capabilities. Intended for medium-throw applications in rental productions and fixed installations, these line sources deliver remarkable acoustic properties and versatility for FOH L/R systems, central clusters, side-fill monitors, distributed systems and complementary fills.

The ARCS® WIDE is suited to achieving an extensive coverage with few elements, offering a remarkably compact array, while preserving sightlines.

The ARCS® FOCUS line source focuses the same acoustic energy within half of the coverage angle and is therefore suited to achieving a narrower coverage and a higher SPL with a more extended throw.

The ARCS® WIDE and ARCS® FOCUS can also be deployed in “WIFO” hybrid arrays for complex audience geometries. The dual directivity pattern and the various system configurations offered to the sound designer and system engineer allow a high level of creative freedom.

ARCS® coverage scalability
All ARCS® systems can be deployed either horizontally or vertically, with a total coverage angle proportional to the number N of ARCS® enclosures in the array. ARCS® can fit applications requiring narrow coverage (15°, 22,5°, 30°) such as fills, standard coverage (75°, 90°) for L/R FOH systems or extended coverage (105°, 120°) for central clusters and up to 360° for in-the-round designs.

This exceptional scalability makes ARCS® a system capable of adjusting to any audience geometry, including the most complex ones.

The main systems components consist of the following:

ARCS® WIDE (H x V: 30° x 90°) element, wide coverage, operating from 55 Hz to 20 kHz;
• ARCS® FOCUS (H x V: 15° x 90°) element, focused energy, operating from 55 Hz to 20 kHz;
• SB18m low frequency extension, operating down to 32 Hz;
• LA4 or LA8 amplified controllers.
The ARCS® WIDE or ARCS® FOCUS line sources provide high SPL with perfect acoustic coupling, a solid LF performance and constant tonal balance over distance. Both systems can be deployed either as a horizontal array or as a vertical array.
 
In the coupling plane, the ARCS® WIDE and ARCS® FOCUS yield a razor-sharp directivity pattern, particularly valuable to sector audience fields while avoiding reflective surfaces. In the other plane, both systems provide a 90° smooth symmetric directivity pattern.

The ARCS® WIDE is suited to achieve an extensive coverage with few elements, offering a remarkably compact array preserving 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°. The ARCS® FOCUS is therefore suited to achieve a narrower coverage, offering a higher SPL with a more extended throw than its sibling.
The ARCS® WIDE and ARCS® FOCUS can also be deployed in “WIFO” hybrid arrays for complex audience geometries. The dual directivity pattern and the various system configurations offered to the sound designer and system engineer allow a high level of creative freedom. Before installation, all these configurations can be acoustically and mechanically modeled with the SOUNDVISION 3D simulation software.
The amplified controllers offer an advanced and precise drive system for the ARCS® WIDE and ARCS® FOCUS enclosures. A single factory preset allows accommodating any application. All L-ACOUSTICS
amplified controllers feature the L-DRIVE, a thermal and over-excursion protection circuit.
Up to 253 L-ACOUSTICS® amplified controllers can be connected together via the Ethernetbased 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 sonic signature.
