The Acoustic Linearity White Paper covers the development of line array loudspeakers from the 1930’s work of Wolfe, I. and Malter, L. on “Directional Radiation of Sound”, through Continuous Source Topology (CST™) technology as applied in the VUE al-Class systems. The paper offers an in-depth view of VUE’s guiding engineering principles used to build upon the existing body of work to bring line array design to the next level.

The VUE team, headed by Michael Adams (Design Chief), details how the al-Class systems achieve a consistent acoustical signature regardless of acoustic elements selected. Additionally the paper covers all aspects of system engineering including horn design, transducer technology, amplifier and dsp integration, VLF (Very Low Frequency) Support Platforms, control software, beam forming and suspension methods.

The paper is intended to enable sound designers, audio consultants, and systems engineers better comprehend the latest advancements in vertical array systems and their deployment. “As the live sound market becomes exceedingly sophisticated, understanding the technologies that push the status quo is increasingly important for consultants, integrators and end-users,” explains Michael Adams, chief engineer for VUE Audiotechnik. “This white paper explores all the critical pieces of a complete line array solution, focusing on achieving optimal performance (in the field) beyond simply tackling sound pressure level.”

VUE al-Class family of line arrays is the practical application of Acoustic Linearity. Our guiding engineering principles and system design platforms coupled with practical suspension techniques ensure a consistent acoustical signature, regardless of the combination of al-Class acoustic elements selected. Advanced DSP and networking connectivity have been integrated into the entire al-Class, ensuring an advanced yet intuitive user interface in SystemVUE Software, enabling professional sound system specialists in both portable and fixed applications to reliably design event- or venue-specific solutions.

The Acoustic Linearity White Paper can also help understand the long-term benefits for any-sized sound company by maximizing inventory usability through loudspeaker system scalability.

VUEDrive™ Systems Engines

VUEDrive™ Systems Engines

VUEDrive™ Brings the Brains and the Brawn 

v4-d-cropThe rack-mount, 2U-sized V3, V4 and V6 Systems Engines provide as many as six dedicated high-efficiency class D amplifier channels (four in the V4) with more than enough “oomph” to tri-amp up to two al-12 elements (V3), four al-8 elements (V6), or bi-amp up to eight al-4 elements (V4). The Systems Engines also incorporate a highly sophisticated DSP architecture that acts as the “nerve center” for the al-Class line arrays along with full network control and monitoring via SystemVUE network and software. All VUEDrive Systems Engines are now fully DANTE compatible.

Fully optimized for every individual component within the al-Class systems, VUE’s next-generation DSP technology combined with Michael Adams’ real-world perspective, enable VUE line arrays arrive from the factory fully ready to plug and play, with minimal tweaking.

The VUEDrive Systems Engines  consists of three models, including the 2-in/4-out V4 for use with the al-4, and the 2-in/6-out V6 for use with the al-8, and the new 1-in/3-out for use with the al-12. Both the V4 and V6 are available in either touring configuration (with front panel LCD interface) or installation configuration (without front panel LCD interface).

VUEPoint Beam Forming Technology

VUEPoint Beam Forming TechnologyVUEPoint-Process-Jul-2014-01For even greater coverage control, al-Class line array systems are fully compatible with the VUEPoint beam forming technology. Developed in partnership with Berlin based AFMG Technologies, GmbH,  VUEPoint is a process that combines VUE’s sophisticated DSP Systems Engine and SystemVUE software with AFMG’s revolutionary FIRmaker technology to enable beam forming (steering) of complex curved arrays of al-Class acoustic elements.
Best of all, VUEPoint can be applied to any VUE Audiotechnik line array system without the need for special upgrades. The complex FIR filter capabilities required for VUEPoint are already integrated into the V4, V6, and V3 Systems Engines and accessed and configured via SystemVUE  in conduction with EASE Focus software.
