Simplified Chart Notes:
1) Modeler
®
software calculates “array pitch” referenced to the acoustic centerline axis of the module in the first (top most) array
position. To convert the Modeler
®
array pitch number to the “array frame” pitch used in the above tables, take the Modeler
®
array
pitch number then add to this number one-half of the nominal coverage angle number of the module in the first array position.
See Figure 10.
2) n/a denotes that array frame pickup point is at maximum; additional pitch requires pull-back bracket with third attachment point.
3) n/a* denotes that WLL limits require use of pull-back bracket to reduce moment force loads; desired pitch may be possible using
additional pickup points of Extender Bars; please consult your local Bose Professional Systems Division Field Engineer or Technical
Support Specialist for additional information.
