Page 15: A12 Rigging System Overview
7 - A12 RIGGING SYSTEM OVERVIEW VTX A12 cabinets include a next generation rigging system that is easy to use, simple to understand and highly accurate. VTX A12 enclosures are transported vertically on carts of four using the VTX A12 VT - Vertical Transporter cart system accessory. During transportation, all four cabinets travel collapsed and set to the 10-degree position. -
Page 16: Vtx A12 - Angle-Lock Mechanism
7.2 - VTX A12 - ANGLE-LOCK MECHANISM VTX A12 includes an innovative Angle-Lock mechanism that automatically engages when the cabinets are suspended and reach the desired angle position. The Angle-Lock mechanism consists of two main parts, the RED LOCKING LEVER and the black RELEASE BUTTON. -
Page 17: Vtx A12 - Angle Selection
7.3 - VTX A12 - ANGLE SELECTION Each VTX A12 includes two Angle Selection panels (one on each side) that are used for selecting the cabinet-to-cabinet splay angle. The options are marked in degrees and the panel allows for 11 unique positions ranging from 0.25-degrees to 10-degrees. -

Page 25: Array Frame And Extension Bar
9 - ARRAY FRAME AND EXTENSION BAR The VTX A12 AF is a lightweight Array Frame used for suspending VTX A12 Series enclosures. The frame was designed to operate in either single-point, front-to-back or side-by-side suspension modes using the VTX A12 AF EB Extension Bar. One Extension Bar is included with the frame and a second extension bar can be added to facilitate side-by-side suspension. -
Page 26: Extension Bar Overview
The Array Frame Extension Bar is used to connect the Array Frame to the suspension points. One Extension Bar is included with the VTX A12 AF and additional Extension Bars can be purchased and used depending on the application. The extension is compatible with 5/8”... -
Page 27: Attaching The Extension Bar
VTX A12 | Rigging Manual 9.3 - ATTACHING THE EXTENSION BAR The Extension Bar includes two tab positions and two Quick Release Pins for connecting to the Array Frame. STEPS: • First, line up the Extension Bar with the connection tabs on the Array Frame •... -
Page 28: Extension Bar Attachment Options
9.4 - EXTENSION BAR ATTACHMENT OPTIONS The VTX A12 AF Extension Bar includes 3 x attachment positions for connecting to the Array Frame. The 3 x positions allow for ad- ditional aiming resolution when an array is suspended from a single point. In single-point applications, the array aiming is determined by the shackle position on the Extension Bar. - Page 29 VTX A12 | Rigging Manual POSITION A The A position is the first extension bar attachment position. This position is used when the array is suspended from two points (Front and Rear, or Side to Side), and can be used for single-point hangs if the prediction shows that a shackle can attach to a physical attachment point on the extension bar.

Page 30: Extension Bar Storage Positions
VTX A12 | Rigging Manual 9.5 - EXTENSION BAR STORAGE POSITIONS The Extension Bar can be secured to the top of the A12 Array Frame for transportation and storage when not in use. Guides have been built into the top of the A12 Array Frame and the storage position of the Extension Bar in order to facilitate quicker attach- ment, and once the Extension Bar is properly in place to be stored, the attached QRP’s from the Extension Bar can be used to... -
Page 31: Extension Bar And Frame Orientation
VTX A12 | Rigging Manual 9.6 - EXTENSION BAR AND FRAME ORIENTATION There are three different positions that can be used to secure the Extension Bar to the Array Frame when preparing to suspend an array. Note that the choice of physical attachment position must come from correct selection of the attachment position in the LAC prediction. -
Page 32: Using Dual Extension Bars
9.7 - USING DUAL EXTENSION BARS The VTX A12 Array Frame can be deployed with either one or two Extension Bars. The Array Frame ships from the factory with one Extension Bar. In cases where a VTX A12 array is to be suspended from side-by-side suspension points, a second VTX A12 Extension Bar can be used. -
Page 33: Extension Bar Use Cases
9.9 - EXTENSION BAR USE CASES The VTX A12 Array Frame can be deployed in a number of configurations with one or two VTX A12 Extension Bars. It is important to note that only certain configurations are correct and safe for suspension of VTX A12 arrays. The images below illustrate proper configurations for attaching VTX A12 Extension Bars, and where suspension points should be attached to the Extension Bars. -
Page 34: Attaching The Array Frame
9.10 - ATTACHING THE ARRAY FRAME The VTX A12 Array Frame was designed to be both lightweight and easy to handle whether it is transported on top of arrays or separately in a case. Since the Extension Bar was designed to attach and travel on the Array Frame, these instructions assume this use case, although transportation together is recommended, it is not required. -
Page 35: Deploying A12 Systems
10 - DEPLOYING A12 SYSTEMS The suspension of a VTX A12 system by a trained technician should be a simple and straightforward process. Ensure all steps below are followed and the array will suspend safely and efficiently. Failure to follow the steps outlined below may damage equipment and/or result in a potentially hazardous condition. -
Page 36: Suspend The First Stack
VTX A12 | Rigging Manual 10.2 - SUSPEND THE FIRST STACK STEPS: • Ensure that all red suspension Locking Levers are in the locked position, and then engage the hoist to lift the array off the ground. As the hoist lifts, each cabinet will expand to the correct inter-enclosure angle, and the sound of pins sliding past locking points will be heard. -
Page 37: Attach The Next Stack
10.3 - ATTACH THE NEXT STACK STEPS: • Raise the suspended cluster of VTX A12 cabinets and align the next cart of VTX A12 cabinets on a Vertical Transporter underneath the suspended cluster. • Once the two clusters are aligned, carefully lower the suspended cluster until the front attachment points are nearly touch- ing the front attachment points of the stacked cluster. - Page 38 VTX A12 | Rigging Manual STEPS: • With the front QRP points set, use the suspension hoist to raise the attached clusters. The second cluster may swing forward slightly as it lifts off the ground and the cabinets expand to their correct inter-enclosure angles. Ensure that the Vertical Transporter is completely off the ground and the cluster is able to fully expand before proceeding to the next step.

Page 40: Disassembling An A12 Array
STEPS: • To de-suspend an array of VTX A12 cabinets, begin by safely lowering the entire array to a working height. • Press the Lock Release Buttons to open the RED Angle-Lock mechanisms for the lower 4 cabinets. This will enable the bottom 4 VTX A12 cabinets to collapse back together to the 10-degree position •... -
Page 41: Close The Angle-Locks And Move Pins To Storage
• Raise the array back up and allow the 4 VTX A12 cabinets on the Vertical Transporter to roll forward until the cart is resting safely on all 4 wheels. When VTX A12 cabinets on the Vertical Transporter reach this position, stop lifting the suspended array. -
