VTX A 12 | Rigging Manual
STEPS:
• Follow the steps in chapter 9 - Deploying A12 Systems to suspend the VTX A12 array using the hoist attached to the Array
Frame.
• Make sure the Suspension Bar attachment tabs have been extended to the outside position so the SB can connect to an A12
cabinet.
• Use the VTX A12 quick release pins to attach the Suspension Bar to the lowest VTX A12 of the array.
• Attach the hoist to the center shackle position of the Suspension Bar and lift the array.
11.3 VTX A12 SB FOR PULL-BACK
The primary role of the Suspension Bar is as a pull-back attachment at the bottom of an array, to facilitate array configurations requiring
a significant amount of downtilt. In this situation, the VTX A12 AF is used at the top of the array for the primary suspension point, with
the VTX A12 SB attached to the bottom of the array and lifted by a second, rear motor point. The two motors are used to achieve the
desired array downtilt.
TIP: Use LAC-3 to determine the ideal spacing between the front and rear attachment points. Make sure the suspension
points are parallel to each other.
