2. The Product
2.1 Product Description
FOHHN® LINEA FOCUS loudspeakers are active, high performance line source systems that can be
remotely controlled and monitored. Equipped with coated 4” long excursion drivers, the systems
have integrated CLASS-D amplifiers and DSP technology specially developed for this area of
application.
The main feature of these systems is their BEAM STEERING TECHNOLOGY. This enables intuitive
control of the systems’ vertical beam dispersion characteristics - in real time –using FOHHN AUDIO
SOFT (Version 5.0.3 or later): the vertical beam width is adjustable from 0° and 90° and the vertical
inclination angle from -40° to +40°, in precise 0.1° increments. This helps to avoid unwanted
reflections from floors and ceilings, while enabling precise, even coverage of audience areas.
Conventional mechanical tilting, i.e. the physical adjustment of the loudspeaker at the venue, is no
longer necessary.
The current version of FOHHN AUDIO SOFT can be downloaded free of charge from
www.fohhn.com .
If higher sound pressure levels are required in the low frequency range, LINEA FOCUS systems can
easily be combined with FOHHN active or passive subwoofers.
LINEA FOCUS has been developed for both mobile and fixed installation applications. The models
described in this manual are fixed installation variants, e.g. for use in churches and cathedrals,
congress halls and exhibition centres, airports and railway stations, theatres, TV studios, university
lecture theatres and auditoria, conference rooms or museums.
The following applies to all LINEA FOCUS models: The longer the line source system, the further its
reach –and the better its ability to precisely control low frequencies.
