The unit shall be constructed as a line-array of sixteen 4" full-range loudspeakers equipped with moisture resistant diaphragms. 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 (power amplifiers one through four shall drive one loudspeaker each, power amplifiers five through eight shall drive three loudspeakers each) and a switched-mode power supply.
