Linea Focus: active, electronically steerable line array speaker. The cream of sound technology. The vertical sound dispersion characteristics of the speaker can be directed towards a specific section of the audience using state-of-the-art digital technology and software from Fohhn without having to alter the speaker position mechanically. Ideal for large churches, cathedrals, railway stations, conference halls, airports, trade fair centres, etc.

Perfect integration
Thanks to the electronic control function, the speaker system can be mounted flatly on the wall or installed directly in the wall, allowing perfect integration into the room architecture.

TWO Beam Technology
The Linea focus system with “two beam technology” developed by Fohhn can generate 2 dispersion beams in the vertical dispersion range. A speaker system can direct sound at a specific area of the dance floor or gallery as a result.

Side Lobe free Technology
This specially developed algorithm can suppress unwanted side lobes.

DSP and Software Technology
Multichannel Fohhn amplifier and DSP technology combined with control software developed by Fohhn gives you complete control of the beam angle, sound characteristics and dynamics. Fohhn® DSP processor technology modulates the Linea Focus and Fohhn subwoofers perfectly. Digital Fohhn signal processors are integral components of active Fohhn subwoofers, Fohhn DSP amplifiers and Fohhn DSP controllers. DSP-controlled Fohhn devices can be controlled remotely from a central location in the room or on the stage via intuitive remote control units. Fohhn therefore offers a perfectly adapted sound system that fulfils all the requirements of a modern speaker system regarding design, sound quality and operating comfort in every respect.

Connections
All connections are fitted flush to the back plate for protection on bottom of LF-120/220:
Input/link: XLR male/female jacks, Power: Powercon mains jack, Network: 2x Fohhn-Net connection jacks.

Configuration
To configure the Linea_focus the Fohhn Audio Soft V3 is indispensable. For connecting the it to a PC the Fohhn-Net Adaptor NA-1 is necessary.

Wide range of application possibilities
large churches, cathedrals, railway stations, conference halls, airports, trade fair centres, etc.

Electronically steerable active line source speaker for mobile applications

Powerful active, electronically steerable line source speaker with aluminium enclosure, equipped with eight coated, long stroke 4” – drivers and digital 8-channel DSP amplifiers. Because of the application of neodymium chassis and an aluminium enclosure, the speaker remains light with only approx. 8 kg. Perfectly suited for dynamic speech- and music transmissions in rooms with demanding acoustics, long reverberation times and challenging architecture. The eight integrated digital amplifiers with 100 W each generate acoustic pressure of maximal 1124 dB. The speaker has a wide frequency range of 60 Hz to 17 kHz. The horizontal dispersion of 110° and the adjustable vertical sound inclination angle of 0° to 90° in steps of 0,1° allow an exact adjustment onto the audience. The inclination angle of the beam can be adjusted from + 40° to - 40° in steps of 0,1°. 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. The acoustic centres of both beams can be set anywhere from 0% (at the bottom of the column) to 100% (at the very top), making the speaker suitable for use in the most challenging acoustic conditions. Unwanted side lobes which occur because of interferences are suppressed effectively through a specially developed Optimize-Algorithm. The adjustment 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. Optically appealing, slim and inconspicuous aluminium enclosure with rounded sides, available in black or white powder coating. Optional available in all RAL Classic colours and Fohhn Texture Design. 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 5 W 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 available.
