The unit shall be constructed as a line-array of sixteen 4" full-range loudspeakers equipped with moisture resistant diaphragms and four horn loaded dome tweeters. The individual loudspeakers shall be positioned according to a patented scheme.
All signal processing functions, necessary to properly drive a directivity controlled line-array with electronically aiming properties, shall be implemented on-board in order to reduce the overhead costs related to external connections. The complete electronics shall be mounted on a chassis which is placed in a separated compartment at the front-side of the enclosure. Electronics shall consist of an audio input module, two input / sixteen output channel DSP section, sixteen power amplifiers with protection circuitry and a switched-mode power supply. Power amplifiers one through four each shall drive a single HF element, power amplifiers five through twelve shall drive one loudspeaker each, power amplifier thirteen to sixteen shall drive two loudspeakers each.
