Main features

LEN-150 er en passiv 100 volt line source højttaler, der er certificeret i henhold til EN 54-24 type B til brug i varslingssystemer. Som alle produkter i Voice Alarm -serien er den udstyret med et vejrbestandigt, stålforstærket aluminiumshus, hvilket gør den lige velegnet til indendørs og udendørs brug. LEN-søjlehøjttalerne garanterer fremragende taleforståelighed og lang rækkevidde selv i vanskelige akustiske miljøer.

12 × belagt 4" chassis
Jævn dækning og spredning
Undertrykkelse af uønskede sidelober takket være Fohhn Source Division Waveguide
IP65 med monteret »kabelforsnæringssæt« (medfølger), i overensstemmelse med EN/IEC 60529
Det er nyt: Fleksibel montering takket være T-sporet på bagsiden
Fås i forskellige farver (RAL Classic, Pantone, NCS) eller med Fohhn Texture Design
For at sikre optimal ydeevne og driftssikkerhed er det nødvendigt med Fohhn systemforstærkere med den korrekte højttalerindstilling.
