The KF760 Series is comprised of two large-format line array modules that incorporate numerous EAW breakthrough technologies to provide premium performance for high-output portable and installed applications, including concert/touring sound, corporate A/V, sports arenas, performing arts centers, theatre venues, and even larger live clubs.

The KF760 is a longer throw module (80-degree horizontal dispersion) while the KF761 is a shorter throw module with wider (110-degree) horizontal dispersion for optimum coverage at closer/front audience regions. Featuring EAW's advanced Divergence Shading, where all loudspeakers are powered at equal level, a full KF760/761 array can provide uniform sound coverage from directly beneath itself out to hundreds of feet without complex signal processing.

To get the required output from the KF760 long-throw module, EAW engineers drew from PPST, VA4, and SuperSub technologies in designing the KF760 Series HF, MF and LF subsystems, respectively. Both modules have a single large horn mouth for the HF and MF subsystem.

	The KF760 is packed with purposeful technology.

The KF760 module is also outfitted with a parabolic separator - borrowed from the KF910F – that serves both to combine the vertically separated HF cells as well as to delay a portion of the MF drivers' output, creating a "flatter" wavefront through the mid- and high-frequency ranges. The KF761 module, meanwhile, features a single HF compression driver and direct radiating midrange cones, allowing it to provide concert-level output in the nearfield without harshness.

Both the KF760 and KF761 have the same LF section, featuring our Bent Horn technology that greatly increases output efficiency. The mouths of the LF horns are vertical rectangular slots on each side of the enclosure front. Given the typical length of most KF760 Series arrays, these slots create a true line array for low frequencies, with vertical pattern control to below 100 Hz. This prevents excessive low frequencies near to and almost under the array while focusing more energy to the longer throws.

Signal processing requirements for the arrays are intentionally simple, allowing users to draw upon intuitive system-tuning techniques such as adjusting box-to-box angles or EQ settings to achieve desired sound quality.

	While it’s not required, the use of EAW UX8800 digital processing with Gunness Focusing takes KF760 performance to new heights.

Headlining the processing is EAW’s revolutionary Gunness Focusing alignment and driver processing algorithms, available via the EAW UX8800 dual-mode digital processor. Gunness Focusing eliminates the traditional characteristics of “honk” and “splashiness” to produce horn-loaded performance comparable to premium direct-radiating studio monitors.

EAWPilot control software provides comprehensive DSP control of the UX8800, while its Wizard modeling software helps in automatically configuring array DSP for optimal performance fitting specific audience areas, greatly simplifying system setup and alignment.

	Wizard uses venue dimensions to create optimized array designs, and much more.

Wizard’s capability also extends to providing the user with input on building optimum array structures and selecting correct pick-points on the array flybars for a given array configuration (Wizard is also available as a stand-alone program for those not utilizing UX8800 processors.)

KF760 Series modules are specifically optimized to couple vertically, the key factor in maximizing line array benefits. When arrayed in a factory-recommended configuration, module faces are virtually continuous, creating a unified wavefront regardless of the box-to-box angles. This permits arrays to provide remarkably consistent front-to-back coverage without gaps or hot spots.

	In a properly configured KF760 array, a flat-fronted upper section focuses the most SPL within a given coverage area for long throw. Two lower sections, each with progressively more curvature, focus less SPL within a given coverage area for medium and short throws. The most tightly curved section, comprised of KF761's, focuses even lower SPL within a given coverage area for nearfield.

Each module's rigging hardware and trapezoidal angles are optimized to create arrays with varying curvature while maintaining a consistent face-to-face distance of approximately 0.25-inch, a key concern in maintaining line array benefits. This is done simply by varying splay angles using the rear of the enclosures. Thus, designers can configure arrays to provide coverage to disparate audience areas without compromising system performance.

Vertical coverage for KF760 arrays are set by varying the rear splay of the enclosures, leaving the fronts tight-packed. This configuration produces a continuous, coherent wavefront from the array, projecting extended-range, high-resolution sound over its full coverage area.

This approach yields an additional benefit: KF760 arrays can provide radical curvature for down-fill coverage - even 90 degrees below horizontal - without being pulled back over the stage. This makes for a more manageable stage environment, produces higher gain before feedback, and eliminates/lessens the need for frontfill systems.

The proprietary rigging system uses captured hinges housed in high strength tubular steel at the four corners of each module. Quick release pins connect the modules at various angles and also lock the hinges, creating a fully rigid array. The front hinge is designed to maintain a consistent 0.25-in gap between boxes, regardless of the angle.

Cut from the same cloth as the earthshaking KF940 SuperSub, the BH760 bent horn subwoofer is engineered as both a companion to the KF760 Series and for other applications requiring extremely high output at low frequencies.

	BH760 subs make an ideal KF760 companion.

Bent horn technology provides a 12-foot horn with a minimal footprint, with dual 12-inch high powered drivers delivering excellent transient response. A 45-inch cabinet depth matches the KF760/761’s width for convenient, stable truck packing in portable applications.

The KF760 Series is one of professional audio’s most utilized line array systems with good reason. A combination of smartly applied leading-edge technologies in just the right package makes all the difference.
