Array Configuration
The Array Configuration tab describes the array and provides information about weight factors
and center of gravity (CG), along with mechanical validation of the array. The array weight
design factor is selectable between 5:1, 7:1, and 10:1. Frame options are selectable. If the array
configuration falls outside the load limits of either the speaker cabinets, the speaker interconnect
system, or the suspension system, this will be indicated via an error indication. Array statistics like
total weight, attach point span, and array height and depth are also calculated.
There are two types of warning messages, which show in red lettering at the top of the Suspension
Detail and Mapping graphics: One is “Invalid CG Location” which is when the center of gravity (CG)
is outside of the two suspension points. This indicates that the array aiming angle is not physically
achievable. A second warning is “Array exceeds load limit conditions” (may also include additional
information about which load limit factor is exceeded). This indicates that one or more of the
components of the array exceeds the selected Design Factor
