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.
