AR-215
3-Way, Line Array unit
High Power and High
Directivity
|
| Applications |
|
This powerful and highly modular system offers great directivity and
flexibility.
Therefore it can be used to sound small events up from one thousand listeners to large concerts in open spaces.
It meets the standards of the SLAS,
(Scalable Line Array System), which adapts easily and can be used successfully in the most diverse tasks.
Although the system has been designed to cover medium to long distances, (Long Throw), it can, just by adding near field units from the same series, (AR-210), become a full coverage P.A. for medium to large events.
The minimum configuration consist of four AR-215, the full advantage of a Line Array rig is reached with eight units.
Furthermore, the AR-215 offers full-range response, (45Hz-18KHz), which permits, in many cases, its use without subwoofers.
When these are necessary, the Series' own
ARS-218 will reproduce the frequencies as low as 30Hz, filling-in that band of frequencies up to the 80Hz mark.

ARRAYS |
The configurable Arrays obtained with the AR-215 are scalable system, (SLAS), easily and rapidly adapted to any particular need. They follow the theory of the spiral
Line Arrays. The enclosures have to be flown vertically and oriented according to the coverage required and always as a multi-enclosure system.
The 90º Horizontal coverage is constantly maintained, regardless of the Splay between the units and their amount, directly proportional to the Vertical Coverage required.
The Vertical Coverage needed, as well as the SPL, are obtained through preset Splay angulations, while the array is assembled on the ground and depend on the number of AR-215 enclosures used.
Our very user-friendly flying fixtures permit choosing the Splay angles between 0 and 10º
according to the EASE Focus Aiming
Software for AR-215 and avoids the disagreeable chore of having to do so simultaneously to lifting the cabinets.
Up to twenty AR-215 can be flown from the supporting frame TF-215. When the Bottom frame
BF-215 is installed and the sling tight between the two, the array becomes a solid assembly free from any unwanted movement or vibration.
The Bottom Frame permits as well to fly under the main systems, smaller Line Array units, (AR-210), much more efficient and predictable than any ground stacked front-fill. These enclosures have a greater Horizontal Coverage of 120º to achieve a perfect near field presence. |

TF-215 Assembly Bottom Frame
Designed to support up to twenty AR-215, the frame is made of laser cut steel, with an epoxy finish. It lifts the suspended Line Array from one or two anchoring points. The back transversal bar receives
the slings to rigidify the Array with the use of
the Bottom Frame. |
|
BF-215 Assembly Bottom Frame
Built from laser cut steel, this frame serves the purpose of rigidifying the Array permitting the tensioning of the slings placed on the Top Frame. It also receives the
interface frame IFF-210 to assemble
the smaller AR-210 Line Array units. |

DAR-215 Protection cover and transport dolly
This rugged front cover provides exceptional protection to the AR-215 enclosures and permits an easy handling on horizontal surfaces thanks to its heavy-duty castors. A positive locking system makes them an integral part of the enclosure and fit for extreme transport conditions. While not in use, they stack to become unobtrusive. |

Assembly Frames, Transport Flight-case
This rigid, ergonomic and practical
transport flight-case accepts two double sets of top and bottom frames.
All inner surfaces are lined with high-density polyurethane foam and divided so that every element is individually protected. |

The AR-215 enclosure is part of a Series of systems, which allows the assembly of different Line Arrays.
As with all other components in this Series, it has been conceived to offer very high sonic performance, outstanding presence and extreme clarity, while meeting each and every one of the parameters that define the Line Array Technology.
The various elements found in the enclosure make use of sophisticated loudspeaker coupling techniques in order to implement the appropriate shading, thus permitting total control of the horizontal dispersion and avoiding the cancellations inherent to conventional P.A. Systems.
Furthermore, the use of complex wave-guides, permits an absolute control over the vertical coverage, an utmost necessity when directing our sonic energy to specific areas.
The end result is clear message without bouncing or reflected specific frequencies. The necessary Vertical Coverage is obtained via the system's enclosures separation and angle setting between the same.
The full Line Array system will produce a coherent wave front, which provides the interesting peculiarity of only
losing 3dB every time we double the distance from the sound source. Conventional system
lose 6dB in the same circumstances. This Line Array inherent advantage permits large SPL at long distances while offering bearable levels in the near field.
Another noticeable point is the easy set up procedure, thanks to our rugged and reliable flying assembly that permits a precise yet rapid installation.
