Focus

FM/I-400

The FM/I-400 is an active low-mid module from the Focus series. As with all products in this series, the Fohhn Beam Steering Technology provides real-time, software-controllable dispersion and eliminates the need for mechanical tilting. Developed for demanding mobile applications and fixed installations, the FM/I-400 achieves high sound pressure levels and can be flexibly combined with the FM/I-100/110 high frequency modules and further enhanced with the DLM-300 low-mid extension.

Main features

  • Available as FM variant for mobile applications or FMI variant for fixed installations
  • 32 × 4" long excursion driver
  • 16 integrated class-D amplifiers with DSP
  • SPL max. of a module: 134 dB (94 dB @ 100 m)
  • Up to 6 modules in one stack
  • Frequency range: 60 Hz – 17 kHz
  • Convenient real-time control of vertical dispersion with Fohhn Audio Soft
  • Vertical beam width: 0° to 90°, sound inclination angle: -40° to +40° (adjusted in 0.1° increments)
  • Fohhn Two Beam Technology (two separate dispersion beams)
  • Fohhn Side Lobe Free Technology (suppression of side lobes)
  • Acoustic centre displaceable over entire line length
  • Easy rigging thanks to the Fohhn Quicklock System
  • Integration in evacuation systems according to DIN EN 60849 / VDE 0828
  • Green power standby mode
