SPECIFICATIONS KF761 DESCRIPTION The KF761 is part of the KF760 Line Array Series. The KF760 Series uses advanced divergence shading where all loudspeakers 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 processing. Vertical coverage for the array is set by varying the splay of the rear of the enclosures, leaving the fronts tightpacked. This configuration produces a continuous, coherent wavefront from the array, projecting extended range, high resolution 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. APPLICATION This high output touring system is scalable from theaters under 1,000 seats to stadiums. The KF761 has two applications. 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 performance. When used with KF760s they can be used singly or in multiples depending on the coverage needed. For extending the low frequency response, KF940 bent horn subwoofers are an ideal complement to KF761s or a KF760 Series array.

The LF transducers shall each be loaded into a proprietary bent-horn, with the horn mouths horizontally separated to provide controlled off-axis cancellations to match the MF beamwidth through the crossover region. The MF transducers shall both be coupled into a single large format horn. The HF transducer shall be coupled to an HF horn coaxially mounted with, and extended by, the MF horn. The system shall have a nominal dispersion pattern of 100° (h) when used as part of a KF760 or KF761 line array. System frequency response shall vary no more than ±3 dB from 80Hz to 16kHz measured on axis. The single loudspeaker’s subsystems (LF/MF/HF) shall produce Sound Pressure Level (SPL) of 96/107/112 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 135/140/140 dB SPL on axis at 1 meter. The subsystems (LF/MF/HF) shall handle 2000/500/150 Watts of amplifier power (continuous) and shall have nominal impedances of 2x 8/8/8 Ohms. The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of void-free cross-grain-laminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in wear-resistant textured black paint. Input connector shall be a Neutrik NL8 with an additional NL8 provided for connect through. Proprietary rigging is provided for arraying. The front of the loudspeaker shall be covered with a powder coated perforated steel grille. The tri-amplified, three-way full range loudspeaker system shall be the EAW model KF761. 29.60 4X .875 SQ 11.44 7.94 8.02 12° C 12° L 6.96 8.61 4X HANDLES RIGHT SIDE 509148 (0) 6/28/01 DIMENSIONS APPLY TO BOTH SIDES Manufacturing tolerances are +/- 0.13 and +/- 1° One Main Street, Whitinsville, MA 01588 508 234 6158 Toll Free 800 992 5013 EAW products are continually improved.
