JBL IVX-587550 IntelliDisc-DS90


Fully Integrated Digitally Controlled Two Dimensional Loudspeaker Array

The JBL Professional® IntelliDisc-DS90 is the world’s first fully integrated, digitally controlled, two dimensional loudspeaker array. The IntelliDisc utilizes our DDS technology allowing control over both the horizontal and vertical beam steering. The dispersion can be shaped to a very narrow beam, keeping sound away from areas where it is not wanted. The beam can then be digitally steered to the left, to the right, up or down.
DDS stands for Digital Directivity Synthesis, which is a highly advanced array control optimization concept.
DDS is based on a unique, specially adapted ‘constrained weighted least-squares’ optimization algorithm. Starting from a desired direct SPL distribution in a hall or space, the optimum output filter for each array channel is calculated. In other words, the desired ‘illumination’ of the hall or space is ‘mapped’ back to the array, instead of mapping the array response to the hall, as would be done with a conventional loudspeaker array.
Using DDS technology any desired two dimensional radiation pattern can be synthesized from the IntelliDisc-DS90. This allows users to ‘mould’ both the vertical and horizontal dispersion of the array to perfectly fit the audience area; whilst at the same time avoiding unwanted reflections and spill. The result is an array which can offer a high ratio of direct sound to reverberant sound, which is critical for achieving high levels of speech intelligibility, in the most difficult of acoustic environments. In addition to this the unit can reduce noise nuisance in outdoor applications.
