Current Steered Solutions (Column Beam Steering, Steered Line Arrays) VS Plane Array™

Beam-steering technology

EDC Acoustics Plane Array^TM technology is uniquely different to current beam-steered technology. Current beam-steering technology on the market typically features single dimension control only -usually with horizontal control limited to the mechanical design of the speaker itself. Current beam-steering technology acts as a planar array creating a naturally narrow dispersion, and utilises FIR filters, amplitude shading and/or low pass filtering to broaden the beam angle in a single dimension. This results in a product that is naturally convergent (narrow dispersion) and manipulated to produce wider dispersions. Linear algorithms can also be applied to create simple pan and tilt of the beam. As the beam-steered product is broadened, its peak SPL ability is reduced. In most instances there is potentially only a small proportion of speaker drivers (perhaps even one)operating at high frequencies and at full power for a broad-beam dispersion.Some existing steered technologies utilize a conventional compression driver and horn arrangement to regain high frequency acoustic energy, but in doing so eliminate the beam-steering ability of high frequencies. FIR filter control additionally creates phase response differences between acoustic sources, which reduces both acoustic qualities and maximum amplitude summation for high frequencies. Once a system is equalized for typical use, the result is a limitation on SPL. As such, current beam-steered technology is typically limited to speech/background/foreground music applications.

What are the benefits?

EDC Acoustics Plane Array^TM technology uses special patented algorithms to create both narrow and broad acoustic dispersions. These patented algorithms do not use FIR filters, do not use amplitude shading and do not use low pass filtering to broaden acoustic spread.Furthermore, our algorithms apply a phase constant output between all out put devices. The result is highly coherent sound, with all transducers providing full bandwidth power capabilities all of the time. Every driver is working to its maximum capabilities and across its entire operating bandwidth all of the time - regardless of a narrow or broad configuration. Furthermore, the patented algorithms are not limited to a simple single dimension vertical dispersion, or even a simple horizontal and vertical dispersion. Complex 3-D acoustic wavefronts can be created using special algorithms that can curve, skew, slope and tilt the wavefront to create almost limitless acoustic shapes. As such, EDCAcoustics Plane Array^TM technology is not limited to speech and background music applications, but is also supportive of concert level SPL -whilst providing the coherence and transient response comparable to a studio monitor.
