L-Acoustics ARCS series shaped for sound


The Arcs Wide and Arcs Focus systems from L-Acoustics have designs based on two constant curvature enclosures, which ensure distant directivity pattern and SPL capabilities. The systems are primarily


made for medium-throw application in fixed installations but are versatile in that they can also be deployed in rental applications. The line sources deliver the necessary performance for applications including FOH L/R systems, central clusters, side-fill monitors, distributed systems and complementary fills. Both line sources provide high SPL with a high standard of acoustic coupling. Coverage angle of the Arcs Wide line source is proportional to the number of enclosures in the array: N x 30º. By contrast, the Arcs Focus line sources focus the same acoustic energy within half of the coverage angle: Nx15º. The Arcs Focus is therefore suited to achieve a narrower coverage, offering higher SPL with a more


extended throw than its sibling. Another benefit of the


systems is that they can also be combined in hybrid arrays for complex audience geometries. The dual directivity pattern and the various possible speaker configurations allow a high level of creative freedom, according to L-Acoustics. Before installation, these configurations can be acoustically and mechanically modelled with the company’s Soundvision 3D simulation software. The company’s LA4X and LA8 amplified controllers sit at the heart of the system and can be monitored and controlled in real time using the LA-Network manager software. www.l-acoustics.com


VUE Audiotechnik al-8 line array


VUE Audiotechnik’s flagship al-8 line array offers versatility and sound quality in mainstream line array applications. It features state-of-the-art transducers – including VUE’s unique beryllium compression drivers – as well as intelligent system electronics, on-board SystemVUE networking and full compatibility with VUEPoint beam steering technology.


al-8 is an adaptable array


system that is suitable for numerous applications. The company’s rackmounted V6 System Engine acts as the system’s optimised DSP/ amplifier. VUE believes its DSP technology improves out-of- the-box performance while streamlining set-up. Installers assemble the array and then select the appropriate configuration from the SystemVUE software. The result is that minimal EQ or tweaking is required, so the operator is free to concentrate on creating the mix.

The self-powered LYON linear sound reinforcement system is the newest addition to the Meyer Sound LEO family of linear loudspeakers. The company believes that by incorporating the technology of the LEO family in a lighter and more compact package, LYON extends the advantages


of highly linear self-powered systems to a broader range of venues and applications. To make a solution


possible for numerous types of installation – offering maximum flexible in system design – LYON is available in two versions. The LYON-M main loudspeaker serves as


the anchor for installations in arenas and large auditoriums, as well as tours and festivals. LYON-W, meanwhile, provides wider horizontal coverage at the bottom of LYON arrays and can also be used for the top of an outfill array for upper side arena seating.


Both the loudspeakers can


work with LEO-M systems, handling the wider coverage needs at the bottom of LEO-M arrays, and serving as outfill or delay arrays when needed. The system features a high peak power output with exceptional linearity and precise transient reproduction at any operating level, and is self-powered for simplified set-up and increased reliability.


What’s more, LYON’s Compass RMS remote monitoring system reports loudspeaker performance statuses, assuring greater reliability. Self-powered technology eliminates power amplifier racks and attendant room cooling requirements. www.meyersound.com


46 July 2014 Martin Audio MLA Compact


The MLA Compact from Martin Audio represents a new direction in the way loudspeaker arrays are configured and controlled. The company believes the device delivers much more consistent sound compared to conventional arrays.


Instead of the line array goal of producing coherent wavefronts as they exit the speaker grilles, MLA Compact focuses on what arrives at the audience. The users/engineer specifies the SPL and frequency response required at various points throughout the venue, and intelligent software controls each of up to 120


individual cells in the array to produce the desired result. Every cell in the array


is controlled by a central computer, meaning the MLA Compact is not constrained by the 3dB decrease in SPL with doubling of distance that is associated with conventional line arrays.


Instead, the


frequency response and SPL at the farthest seats closely track those at the front rows. ‘Hard-avoid’ areas such as ceilings and rear walls can be programmed in and vertical coverage can be fine-tuned electronically. This is very significant, given the acoustic challenges that large-venue installations can present.


This way of operating a line array also removes trial and error from the outcomes. www.martin-audio.com
