The KF761 is part of the KF760 Line Array Series. The KF760
Series uses advanced divergence shading where all loud-
speakers are powered at equal level. A full KF760/KF761 array
can provide uniform sound coverage from directly beneath
itself out to hundreds of feet without complex signal pro-
cessing. Vertical coverage for the array is set by varying the
splay of the rear of the enclosures, leaving the fronts tight-
packed. This configuration produces a continuous, coherent
wavefront from the array, projecting extended range, high res-
olution sound over its full coverage area.
Fully professional construction features include Baltic birch
plywood enclosures, heavy-duty steel grilles, Neutrik NL8
connectors, heavy duty bar handles, rear hand-holds, and
accessory caster pallets. Six Year Warranty.
This high output touring system is scalable from theaters
under 1,000 seats to stadiums. The KF761 has two applica-
tions. KF761s are designed to supplement KF760s in an array
to provide near-field coverage for distances less than 70 feet.
The KF761 can also be used as part of a KF761-only array for
applications with coverage distances up to about 100 feet.
The minimum KF761 array size is four enclosures for full per-
formance. When used with KF760s they can be used singly or
in multiples depending on the coverage needed. For extend-
ing the low frequency response, KF940 bent horn subwoofers
are an ideal complement to KF761s or a KF760 Series array.
