4.1.1 Side Lobe Free Technology 

Due to their construction, line source and line-array speakers generate unwanted Side Lobes in their 
vertical  axes.  These  result  from  the  distances  between  the  individual  loudspeaker  chassis  and  the 
finite length of an array.  

 

Beam with Side Lobes 

 

Linea  Focus

  systems  are  equipped  with 

Fohhn  Side  Lobe  Free  Technology

:  A  specially  developed 

algorithm effectively reduces the side lobes. This results in fewer unwanted sound reflections in the 
room.  Consequently,  levels  of  speech  intelligibility  are  improved  and  feedback  prevention  is 
increased.  

 

Optimized beam with Fohhn Side Lobe Free Technology
