Prijs op aanvraag


Electronically steerable line array speakers allow perfect adaptation to the room architecture and acoustics.

Active, electronically steerable line array speaker, 8x 4? neodymium speaker, digital 8-channel DSP amplifier integrated, 8 separate DSP channels, vertical sound dispersion, digitally controlled (beam angle: 0° to 40°), vertical sound inclination angle, digitally controlled (-40° to +40°), horizontal sound dispersion: 110°, aluminium housing in all RAL colours, length: 125 cm, weight: 8 kg.

  • Electronically steerable, using integral amplifier and DSP technology
  • Individual control of beam and beam angle in realtime
  • TWO beam technology (2 dispersion beams possible)
  • Intuitive control software
  • Option of cascading several systems
  • Excellent sound and extremely dynamic speech and reproduction music
  • Aluminium designer housing in all RAL colours

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.

Cascade function
Two Linea_focus systems can be cascaded. The resulting extension of the speaker row increases the projection range and sound pressure level significantly as well as extending the frequency range of sound directed at the audience. Doubling the line length quadruples the projection range.

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. 

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.

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.

NA-1 Fohhn-Net USB adapter and Fohhn Audio Soft on CD Rom. Extensionable with XLR microphone cable. Aluminium housing and adapter cable.

Fohhn Audio Soft

Easy, convenient handling Laptop and Fohhn Audio Software for intuitive control and monitoring of all connected Fohhn audio devices with integrated DSP. Clear graphical user interface for rapid access to the speaker database, status display and all audio devices integrated in the Fohhn DSP.

Electronically steerable active line source speaker

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 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 100W each generate acoustic pressure of maximal 124 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.
