D&b audiotechnik introduces the augmented array concept in its new A Series

The manufacturer has presented this system in the recent edition of InfoComm 2019, including AL60 and AL90 speakers, as well as the ALi60 and ALi90 boxes, Designed for permanent installations.

The new A-Series of D&b audiotechnik It offers as a novelty an advanced concept of speaker -the augmented arrangement-, that arises from the evolution of the system applied by this manufacturer, and that has been shown for the first time during its participation in InfoComm 2019.

With a combination of varying angles between boxes, Two acoustic optimization concepts and an advanced waveguide design, Series A covers applications where coverage flexibility is paramount, in both horizontal and vertical placements.

The A-Series embodies all the adaptability of a point source cluster with the complete control options of an online array of&B. System includes AL60 and AL90 speakers, in addition to the ALi60 and ALi90 boxes, Designed specifically for permanent installations.

With the right structure, up to four AL60/AL90 and Ali60/ALi90 speakers can be hung in vertical or horizontal arrangements. Variable angles between adjacent boxes can be configured in five-degree increments, from -10º to +10º, allowing precision adjustments to be made and ensuring sound is directed exactly where it is desired.

The Directivity Control function of the mid-frequency range (MDC) ensures that 200 Hz and 2 kHz are evenly distributed, regardless of the adjustments of the angles between the boxes. With a horizontal dispersion of 60° and a control of the directivity up to 550 hz, approximately, The AL60/ALi60 speaker can cover a distance of up to 30 metre.

The AL90/ALi90 speaker, with horizontal pattern control from 90° to 370 hz, is sonic and mechanically compatible, ensuring that the same optimal acoustics result is consistently achieved everywhere, at any angle and whatever the configuration.

In addition, AL60/AL90 speakers share a passive two-way design and include a high-frequency compression motor (HF) 1.4" output with a 3" diaphragm mounted on a wave molding device, as well as two low-frequency motors (Lf) 10" neodymium.

A sophisticated waveguide design, combined with the symmetrical dipole arrangement of low frequency motors (Lf) Enables uniform overlap of adjacent frequency bands in crossover design. The resulting wave segments of each of the boxes will be added together and without cancellations.

Compatible with a wide range of amplifiers and subwoofers d&B, makes it easy for the entire system to be customized to meet specific application needs. Four-channel amplifiers -30D, D20 and D80- accompanying them provide complete user-definable EQ.

In addition, have in two equalizers of sixteen bands with parametric filters -Notch, Shelving and asymmetrical-, as well as delay functions of up to ten seconds. V-GSUB and Vi-GSUB recommended for low frequency extension with Series A, with many more options available for mobile and installation apps, big or small.

Wolfgang Schulz, product manager at d&B, notes that "the augmented A-Series array provides our customers with a new set of scalable solutions., that work as a standalone system or combined with our range of systems. The flexibility of angles between boxes, Directivity control function of the mid-frequency range and ArrayProcessing capabilities cover a wide range of applications, with a uniformity of coverage that is unparalleled".
