11.7 WHEN CAN I USE THE SB AS A FRAME?
The LAC-3 example below illustrates a scenario where it is appropriate to use the VTX A12 SB as the main array frame.
LAC - Example 4 CoG at rear suspension point
LAC - Example 5 SB as top frame
The venue geometry below calls for an array with its CoG perfectly lined up with the rear suspension point of the top A12 enclosure
(LAC - Example 4). The flexibility of an Array Frame combined with an Extension Bar is not needed here, and a Suspension Bar can be
used instead of an Array Frame (LAC - Example 5).
