11.4 VTX A12 SB AS A FRAME AND PULL-BACK
If two suspension hoists are available for front and back attachment, then Suspension Bars can be used for both the top and bottom
frames on a VTX A12 array. This configuration can reduce both cost and the overall weight of an array when the flexibility of the main
Array Frame is not needed. Permanent installations, in particular, can benefit from this arrangement. However, being less flexible, this
method can take longer to assemble and install than the combination of an Array Frame and Suspension Bar.

STEPS:
• Follow the instructions in chapter 9 - Deploying A12 Systems to suspend the A12 array.
• Set the top A12 cabinet (connected to the Suspension Bar) to the 10-degree position.
• After the entire A12 array has been assembled, seat the second Suspension Bar onto the bottom cabinet in the array.
• Use the VTX A12 quick release pins to secure the Suspension Bar to the bottom cabinet. Attach the hoist to the center shackle
position of the Suspension Bar and lift the array.
