Electronically steerable active line source speaker

Powerful active, electronically steerable line source speaker with aluminium enclosure, equipped with 16 coated, long stroke 4? ? drivers and digital 16-channel DSP amplifiers. Because of the application of neodymium chassis and an aluminium enclosure, the speaker remains light with only 15 kg, including electronics. Perfectly suited for dynamic speech- and music transmissions in rooms with demanding acoustics, long reverberation times and challenging architecture. The 16 integrated digital amplifiers with 100W each generate acoustic pressure of maximal 130 dB. The speaker has a wide frequency range of 60Hz to 17kHz. The horizontal dispersion of 110° and the adjustable vertical sound inclination angle of 0° to 40° in steps of 1° allow an exact adjustment onto the audience. The inclination angle of the beam can be adjusted from + 40° to - 40° in steps of 0,5°. The Linea focus system can generate two dispersion beams and is therefore able to reach additional areas such as galleries. It is possible to high-pass filter the beams separately. Unwanted side lobes which occur because of interferences are suppressed effectively through a specially developed Optimize-Algorithm. The adjustment and monitoring of all parameters is controlled in real time with Fohhn Audio Soft V3.0. The handling is easy and intuitive done via mouse click. The dispersion of the speaker, the sound level and the frequency are graphically visualized. To increase the range, two Linea_focus systems can be cascaded. Optically appealing, slim and inconspicuous aluminium enclosure with rounded sides, available in black anodized or white matt varnish. Optional available in all RAL-colours. For the protection of the speaker chassis and the electronics, the enclosure is equipped with a ball impact resistant, extremely sound-permeable front grille, which is made of powder-coated steel as well as a moisture- and dust repellent acoustic fleece. Highly efficient Green Power supply with a maximum activity input of 5W in stand-by mode. Six pieces M6 thread applications are integrated to the admission of system brackets. Connections: 1x XLR in, 1x XLR through, 1x Powercon, 2x network RJ45. Specific brackets to assemble the system on ceilings, walls, traverses and stands are optionally available. Simulation data CAAD for EASE are in preparation.
