al-8 Line Array System

The al-8 Compact Line Array System picks up where the al-4 Subcompact Line Array System leaves off. The al-8 ‘Acoustic Linearity’ element utilizes VUE’s most advanced technologies including CST™ to extract exceptional performance from its compact design. Innovative technologies such as beryllium compression drivers, Kevlar/Neo transducers, precision amplification and DSP, onboard SystemVUE networking, and full compatibility with the VUEPoint beam steering technology allow the highly scalable al-8 to deliver unprecedented performance to a broad range of mid-sized sound reinforcement applications.

FEATURES:

  • Each al-8 Compact Line Array System “block” includes
    four al-8 Acoustic Elements and a single VUEDrive™ V6 Systems Engine
  • Scalable by adding or removing other al-Class acoustic elements,
    or combining multiple al-8 blocks
  • Onboard SystemVUE™ networking
  • Fully compatible with VUEPoint beam steering technology
  • Integrated flying hardware allows quick assembly of arrays of up to 16 elements per flybar
  • Optional flying and transport accessories available
  • The al-8 can be used as elements in complex CST™ Hybrid Array along with al-12’s and al-4’s

Blocking The VUE

The al-8 Line Array System is made up of the al-8 Acoustic Element and rack-mount VUEDrive™ V6 Systems Engine. The V6 combines a highly sophisticated DSP architecture with enough amplifier power to tri-amp up to four al-8 acoustic elements. In addition, onboard SystemVUE networking capabilities allow easy assembly of sophisticated networks with remote management and control available via the intuitive SystemVUE™ control software.

The system is sold in standard blocks, with four al-8 Acoustic Elements and a single V6 Systems Engine comprising a single block. Multiple al-8 blocks can be combined to address larger applications.

For applications where extended low-frequency is required, the al-8 can be used with the al-8SB integrated flyable subwoofer and is fully compatibility with a variety of other VUE subwoofers. Flexible options allow flying, or ground stacking. All al-Class elements are DANTE Enabled.

Easy Assembly and Instant Results

The al-8 Line Array System benefits from a highly sophisticated DSP architecture that allows each individual component-from transducers, amplifiers and cabinets, all the way out to the SystemVUE software itself–to work in perfect harmony for precise control and easy operation. In fact, the technology is so smart, that al-8 designers were able to pre-load the V6 Systems Engine with a library presets that dramatically improve ‘out -of-the-box’ performance while streamlining setup. Operators simply assemble the array, select the desired preset from the SystemVUE software, then align the physical placement. Minimal EQ or tweaking is required and the operator is free to concentrate on creating the perfect mix.

 

 

CST ™ Technology

al-12-Vue-system-overview-03-frontDefinition of Topology: “The study of geometric properties and spatial relations unaffected by the continuous change of shape or size of figures.”

CST™ re-defines the concept of system ‘Scalability’. Acoustic Linearity Architecture paired with CST™ allows the use of multiple different al-Class elements together in an array without sacrificing the elemental line-array theory basics, resulting in a coherent and symmetrical line-source from the largest cabinet at the top of the array, to the smallest under-hung elements. The family of al-Class products feature three line array elements for maximum flexibility in sound design, inventory profitability, unbeatable coherency. Furthermore, the VUE al-Class Line Arrays support VUEPoint™ Beam Forming to further achieve unsurpassable performance and coverage control in any given room configuration.

VUE’S ACOUSTIC LINEARITY WITH CST™ ANOINTS VUE’S al-CLASS AS THE BENCHMARK IN COMPLETE LINE ARRAY SOLUTIONS

al-Class Combination Arrays
The VUE al-Class line arrays are the only system that can combine ultra-compact (al-4), medium format (al-8) and large-format (al-12) enclosures into a single coherent array without compromising  the mid- and high-frequency coherency. This design feature enables a level of unparalleled system versatility. One can create virtually seamless arrays fully optimized for every parameter including coverage, sound pressure level, size and weight. This also expands the capitalization of a rental inventory for all portable applications.

v6i-3-4view-left-01

The  2U-sized V6 Systems Engine is a 2-in/6-out configuration providing six discrete channels of amplification with more than enough “oomph” to tri-amp four al-8 elements.
Inside each V6 chassis are six dedicated amplifiers supplying two channels at 2500 W each for the low frequency, four channels at 800 W each for the mid frequency and high frequency sections. And that’s clean, pure sine wave power rather than the “peak burst” measurement typically used in completive products.
In addition to amplification, the V6 Systems Engine also handles all system processing and management functions, including speaker protection as well as system-optimized alignment of EQ, time and crossover functions. Rear panel signal connections include dual XLR and AES/EBU inputs, with a pair of NL8 connectors for loudspeaker outputs.

Finally, the V6 Systems Engine provides  full networking capabilities via SystemVUE software for Mac and PC, as well as full compatibility with the VUEPoint beam steering technology. Learn more about the VUEDrive™ System Engines. 

Transducers

The al-8 Acoustic Element features a full complement of transducers designed and engineered specifically by VUE for use in the al-8. A pair of precision-engineered 3-inch voice coil, high power 8-inch low-frequency transducers flank four 4-inch, Kevlar-coned Neodymium transducers for the mid-range.

The mid-range units are outfitted with VUE’s unique lateral acoustic shade modules that acoustically “moves” the drivers closer together to optimize directivity of the woofers at their upper operating range for a smooth transition over the entire coverage area.

For the high frequency, the al-8 utilizes a pair of 1-inch exit, neodymium compression drivers with Truextent® beryllium diaphragms. Beryllium technology allows the compression driver to deliver dramatic improvements in HF extension and response linearity that simply cannot be matched by traditional aluminum or titanium designs.

The beryllium compression drivers are mounted to a tightly coupled, precision waveguide with Continuous Source Topology™ that reduces acoustic lobing and provides ideal line array consistency.

All transducers are housed in a rugged birch plywood enclosure protected by a 12-step Dura-Coat LX finish. Integrated flying hardware allows quick assembly of arrays of up to 16 elements per flybar. Rear panel I/O includes NL8 Input and Loop connections for easy daisy-chaining of line array elements. Flexible rigging options allow flying and ground stacking.

Beryllium

The Truextent® Beryllium Advantage

be-diaphagm-03 h-Class full range systems and al-Class line arrays all employ VUE-designed compression drivers that feature a Truextent® beryllium diaphragm at their core. Beryllium outperforms both aluminum and titanium thanks to an extremely high stiffness-to-mass ratio, which dramatically reduces mechanical deformation (breakup) and shifts resonant frequencies outside the audible range. The net result is a more defined HF at much higher SPLs than more conventional materials.
