KF730 ARRAY DESIGN
4.1
KF730 WIZARD
Use the KF730 Wizard for designing KF730 arrays. It can be found in the
Downloads/Software
section of the EAW website (www.eaw.com). The Wizard’s primary function is to determine the
configuration that will provide the best vertical performance for a given application. Various venue
dimensions are entered that allow the Wizard to calculate the resultant array performance. Given
this information, the Wizard works in either of two basic ways, with both displaying the resulting
coverage.
Automatic Mode
: The Wizard will select the optimum number of enclosures, enclosure splays,
array aiming angle, and fly-bar pick point. This can also be done for a given inventory of KF730s
and SB730s. There are variable adjustments for application-specific output levels and for level
consistency for near-to-far listeners.
Manual Mode
: This provides complete control over the array’s configuration. The number of
enclosures, enclosure splays, array aiming angle, and fly-bar pick point can be entered manually.
For complete instructions about operating the KF730 Wizard, click on the About/Help menu when
running the Wizard.
4.1.1
Computer Requirements
The Wizard requires an IBM compatible PC with the Windows® 98, Windows® 98SE, Windows®
2000, Windows® ME, Windows® XP, or Windows NT® operating systems. It is not designed to
work with Windows® 3.x, Windows® 95, or Macintosh® operating systems.

4.2 FILL
COVERAGE
4.2.1 Up-Fill
Some applications, such as theaters and small arenas, can require up-fill coverage from the
array. In this case, the array is designed to tilt back for up-firing coverage from the topmost
enclosures.
4.2.2 Down-Fill
Many applications require extreme down-fill coverage. In this case, the array is designed to have
enough curvature for the bottom KF730 to provide coverage almost directly beneath the array.
4.2.3
Horizontal Coverage and Side-Fill Arrays
Regardless of the length of the array, a KF730 array has a horizontal beamwidth (-6 dB points) of
approximately 110°, with pattern control maintained to a very low frequency.
