The unit shall be constructed as a line-array of fourteen 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 / eight output channel DSP section, eight power amplifiers with protection circuitry and a switched-mode power supply. Power amplifiers one and two shall drive two horn loaded dome tweeter each, power amplifiers three and four shall drive one loudspeaker each, power amplifiers five through eight shall drive three loudspeakers each.
