Planar Array Frames and Rigging Brackets
Planar Array Frames (PAFs) provide a pre-engineered solution to rig several of the
arrays found in this guide. Please refer to the AE Series Bracket and Array Frame
Handbook for more details.
When tilting an array that utilizes a PAF frame downward at angles greater than about 35
degrees, understand that the center section of the array will end up with more down-tilt
than the outside sections. If this is undesirable, consider changing the rigging to a
spherical array (see below), where each box is aimed down independently. Spherical
arrays can require more complex rigging, but have the benefit of independent adjustment
of speakers on each axis.
Often the top tier of a multi-tiered array is aimed downward together at a shallower angle
and the downfill boxes are aimed independently below that. This is how the two-tiered
arrays in this guide are shown.
Planar Array and Spherical Array examples
The following 3-D modeling plots show the effect mentioned above where unwanted
energy from the outer enclosures of a planar array is directed onto the side walls of a
room (fig. 8). The rear delay cluster is also a planar array which exhibits the same
problems. Planar arrays refer to those clusters that have a flat top and bottom array
surface.

and delay center locations.
