4. Control via FOHHN AUDIO SOFT
The complete control of your LINEA FOCUS systems can be exclusively carried out via FOHHN AUDIO
SOFT.
A comprehensive description of the software and all its functions can be found in the separate
FOHHN AUDIO SOFT user manual. You can download this free of charge from our website:

4.1 Beam Steering – the functional principle
In the audio processing world, the term “Beam Steering“ refers to the process of controlling the
beam dispersion characteristics of loudspeaker systems using electronics and software. Through
specific manipulation of signal sources that are tightly positioned in close proximity to one another, it
is possible to precisely control the vertical beam width and inclination angle of the loudspeaker
system over a wide frequency range.
In general: the longer the loudspeaker, the lower the
frequencies that can be included in the “bundle”. Because each speaker driver can be individually
controlled and adjusted, via use of a dedicated algorithm or DSP, this in turn influences the sound
dispersion capability of the entire loudspeaker.

All FOHHN FOCUS-SERIES loudspeaker systems work with Beam Steering Technology.
Combining the DSPs with FOHHN AUDIO SOFT makes it possible to electronically control the
loudspeaker system’s vertical inclination angle and vertical beam width – in real time!
FOHHN AUDIO SOFT enables the entire audio system to be configured in advance, before the
systems themselves are put into operation at the venue.
