5.3 GROUND-STACKED ARRAYS IN LAC-3
Line Array Calculator version 3.5.0 or later includes mechanical safety checks for ground-stacked arrays. The software takes into con-
sideration several variables that can affect the stability of an array, including outside factors such as someone pushing on an array.
Based on this data, LAC-3 generates a safety assessment factor and notifies the user of potential mechanical or stability problems.
Errors and warnings generated fall into one of the following categories:
No errors or messages
In this case, the array is stable under normal conditions and can be used as is. The array
also complies with the mechanical limits set by JBL for the speakers and selected acces-
sories.
WARNING: Stability Hazard! - Stack Could Become Unstable - Secure to Ground
This message is an alert that the array is potentially unstable and a tipping hazard condition
has been detected. The user is responsible for securing the array to the ground, stage, or
other structure that can provide additional support and is rated for the weight of the array.
This message may also be warning of external factors that can influence stability, such as
someone accidentally pushing the array.
Configuration exceeds the maximum number of boxes allowed
This message is presented when the specified array design exceeds the mechanical limits
set by the JBL team for the speakers or selected accessories. Array designs that trigger this
message should not be used under any conditions, as they can lead to hardware damage
and/or injury.
Center of Gravity
Invalid CG Location
This message is presented when the center of gravity of an array design exceeds the foot-
print of the selected accessory. Array designs that trigger this message should not be used
under any conditions, as they can lead to hardware damage and/or injury.
