What is ArrayProcessing
The ArrayProcessing function applies powerful filter algorithms to optimize the tonal (spectral) and level (spatial) performance of a line array column over the audience area defined by its mechanical vertical coverage angle.
Within the d&b ArrayCalc simulation software, spectral and level performance targets over the listening areas can be defined while specific level drops or offsets can be applied to certain areas, to assign reduced level zones.
ArrayProcessing applies a combination of FIR and IIR filters to each individual cabinet in an array to achieve the targeted performance, with an additional latency of only 5.9 ms. This significantly improves the linearity of the response over distance as well as seamlessly correcting for air absorption.
In addition, ArrayProcessing employs the same frequency response targets for all d&b line arrays, to ensure all systems share a common tonality. This provides consistent sonic results regardless of array length or splay settings. The resulting coverage is enhanced with spectral consistency and defined level distribution, achieving more linear dispersion and total system directivity to cover longer distances or steep listening areas effectively.
tutorial 1 – what is ArrayProcessing
The optional ArrayProcessing function within the ArrayCalc simulation software V8 incorporates powerful filter algorithms that calculate and optimize the sonic performance of a d&b line array over an entire listening area. ArrayProcessing ensures that every member of the audience benefits from the same remarkable quality of sound by enhancing the spectral consistency, with a defined level distribution, to achieve a consistent tonal balance for each listener. The optimization intensifies the clarity and tonal balance of the J-Series, V-Series or Y-Series line array solutions; taking existing d&b systems to dizzying heights. ArrayProcessing also applies a target frequency response to different loudspeaker columns, giving each array the same sonic character and coherence, regardless of Series, column length and splay settings.
