The unit shall be constructed as a line-array of seventeen 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 electronical 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 fifteen shall drive one loudspeaker each, power amplifier sixteen shall drive two loudspeakers.
The input section shall be transformer balanced. All necessary array signal processing shall be implemented in the digital domain by means of a 900MFLOPS 32bits DSP.
