Fohhn Ships New Focus Modular Series Line Array Systems

German  loudspeaker manufacturer Fohhn Audio has shipped the first of its new  Focus Modular electronically steerable, active line array  systems. Developed with challenging acoustic situations in mind, the  high performance modular systems combine Fohhn’s flagship beam steering  technology with very high sound pressure levels and wide dynamic ranges  to offer more powerful coverage, long reach and excellent levels of  music reproduction and speech intelligibility. Compact dimensions and light weight ensure effective integration into a range architectural  settings, as well as facilitating transportation and set-up for mobile  applications.

The Focus Modular series comprises three active systems; the FM/FMI-100  high frequency module containing 8 x 1” compression drivers with Fohhn  HF Waveguide and horn, the FM/FMI-110 high frequency module containing  16 x 1” compression drivers with HF Waveguide and horn and the FM/FMI-400, a low-mid module equipped with 32 x 4” long  excursion speakers. The systems also feature integral state-of-the-art,  multi-channel Class D amplifiers and a specially developed  multi-channel DSP processor for beam steering capability. A second DSP provides access to a range of audio tools including  parametric 10-band EQ, compressor/limiter/noise gate, delay, x-over,  status and temperature monitoring and tone generator (sweep tone and  pink noise). A further DSP contains a special algorithm designed to give maximum protection to each individual speaker. This  particular combination of loudspeaker, amplifier and DSP technology  enables the Focus Modular series to achieve maximum SPLs of 139dB  (FMI-400), 142dB (FMI-100) and 148dB (FMI-110), measured at a distance of one metre. The different modules can be combined and  cascaded for a range of applications using Fohhn’s dedicated Quick-Lock  system.

The new modules incorporate the same innovative beam steering technology  that characterizes Fohhn’s Focus Series family as a whole, including  precise real-time adjustment (in 0.1° increments) of  the speakers’ vertical sound inclination angle (-40°/+40°) and vertical beam width (0°-90°). Dual-beam technology enables simultaneous  coverage of different audience areas. A digital high pass filter can be  separately applied to each beam, and the acoustic centre of the  individual beams adjusted in real time and set at any point of the loudspeaker’s line length. A specially developed  algorithm also enables the suppression of any unwanted side lobes in the  beam. The systems can be networked and remotely controlled in real time  via Fohhn’s Audio Soft control software.

Focus Modular systems have been developed for both mobile and permanent  install projects in theatres, concert halls, airports, cathedrals,  conference centres and other public spaces. The  loudspeakers’ slim, elegant design enables them to be mounted flat  against a wall, or installed within the wall itself for complete invisibility.  The systems can be supplied in a full range of RAL colours to blend  with interiors.
