VTX A8 | Rigging Manual 8.3 - A TT ACHING 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
The example below shows how the real and “virtual” positions are spaced across the extension bar. TIP: Refer to JBL’s Line Array Calculator software to determine the best possible shackle position and attachment combi- nation to achieve the required array angle. -
Page 29: Extension Bar Storage Positions
VTX A8 | Rigging Manual 8.5 - EXTENSION BAR STORAGE POSITIONS The Extension Bar can be stored at the top of the Array Frame for transportation and storage when not in use. Guides are available at the top of the Array Frame to guide the Extension Bar to the storage positions. The two large QRP’s are used to secure the Extension Bar on to the Array Frame. -
Page 30: Extension Bar Positioning
VTX A8 | Rigging Manual 8.6 - EXTENSION BAR POSITIONING There are two different positions that can be used to attach the Extension Bar to the Array Frame depending on the overall array angle (tilt) needed. The normal orientation has the extension bar extending towards the rear of the array which allows for the maximum pos- sible down-tilt. -
Page 31: Using Dual Extension Bars
VTX A8 | Rigging Manual 8.7 - USING DUAL EXTENSION BARS The VTX A8 Array Frame can be used with either one or two Extension Bars. The Array Frame ships from the factory with one Extension Bar and an additional Extension Bars can be purchased and used in scenarios where side-by-side suspension points are needed. The standalone version of the Extension Bar (Part# VTX A8 AF EB) includes one Extension Bar, two additional QRP’s and all hardware needed (tabs, bolds and nuts) for mounting to the VTX A8 Array Frame. -

Page 33: Extension Bar Use Cases
VTX A8 | Rigging Manual 8.9 - EXTENSION BAR USE CASES The VTX A8 Array Frame can be deployed in a number of configurations with one or two VTX A8 Extension Bars. It is important to note that only certain configurations are correct and safe for suspension of VTX A8 and B18 arrays. The images below illustrate proper con- figurations for attaching VTX A8 Extension Bars, and where suspension points should be attached to the Extension Bars. -
Page 34: Attaching The Array Frame
VTX A8 | Rigging Manual 8.10 - A TT ACHING THE ARRA Y FRAME Below are the required steps to attach the VTX A8 AF to a stack of four VTX A8 enclosures. STEPS: • To make it easier to attach, separate the Array Frame from the Extension Bar. Ensure that the top cabinet is set to the 4 Degree angle and ensure that the Array Frame is oriented in the proper direction. -
Page 35: Deploying Standalone A8 Systems
VTX A8 | Rigging Manual 9 - DEPLOYING ST ANDALONE A8 SYSTEMS Suspending standalone VTX A8 arrays is a simple and straightforward process. Carefully follow the next few steps to correctly and safely suspend an array. Instructions on how to suspend A8/B18 combination arrays can be found later in this document. 9.1 - PRESELECT THE ANGLES STEPS: Using the Quick Release Pins (QRPs) located on the Angle Selection Panel, select the desired inter-enclosure splay angles for... -
Page 36: Pre-Locking The Angles (Optional Step)
VTX A8 | Rigging Manual 9.2 - PRE-LOCKING THE ANGLES (OPTIONAL STEP) This next step is optional and is not a requirement, but a convenient shortcut. After the angles have been selected, the A8 cabinets can be extended and locked while still on the ground. This can make connecting flown cabinets to cabinets on the ground much easier since the rear rigging connection points are in a much higher in elevation and can connected to the flown arrays much easier. -
Page 37: Suspend The First Stack
VTX A8 | Rigging Manual 9.3 - SUSPEND THE FIRST ST ACK STEPS: Ensure that all red 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 angle. Each cabinet will stop expanding when it reaches the correct inter-enclosure angle. -
Page 38: Attach The Next Stack
VTX A8 | Rigging Manual 9.4 - A TT ACH THE NEXT ST ACK STEPS: • Raise the suspended cluster of VTX A8 cabinets and align the next cart of cabinets underneath the suspended cluster. • Once the two clusters are aligned, carefully lower the suspended cluster until the front attachment points are nearly touching. Ensure that the attachment points are aligned and then lower the suspended cluster until the front attachment points come together. - Page 39 VTX A8 | Rigging Manual STEPS: • After the two front QRPs have been secured, keep lowering the flown array until the rear two connection points come together. Once touching, insert to two rear QRPs to secure the two clusters together. If the angle of the flown cluster is too steep (too much down angle) and the rear connection points are too far apart, follow the steps shown below to safely connect the clusters together.
- Page 40 VTX A8 | Rigging Manual In some cases, the angle of the flown array is too steep to fully connect to the cluster on the ground. This can happen when assembling large arrays or when the frame pick-point is too far back as shown in the example below. In this situation, a two-step process is used to connect all four connection points of the array.

VTX A8 | Rigging Manual 11 - COMBINA TION ARRA YS WITH A8 AND B18 The VTX A8 cabinets are mechanically and acoustically compatible with the VTX B18 single-18” subwoofers. All A8 suspension acces- sories are compatible with the VTX B18 and combination arrays can be create with VTX A8s suspended under B18 subwoofers. This section of the manual covers everything needed to create a VTX A8/B18 combination array. - Page 47 VTX A8 | Rigging Manual Once the frame is connected, lift the B18 off the ground and disconnect the Vertical Transport cart. STEPS: • Use the electric hoists to raise the two B18s off the ground. • Once suspended, remove the VT by first removing the front two QRPs and then the two at the rear. •...

Page 48: Attaching A8 To B18
VTX A8 | Rigging Manual 11.2 - A TT ACHING A8 TO B18 Once the VT has been disconnected from the flown array of B18s, the next step is to attach the first cluster of A8 cabinets to the flown B18s. - Page 49 VTX A8 | Rigging Manual Once the VT has been disconnected from the flown array of B18s, the next step is to attach the first cluster of A8s to the flown B18s. Note that the first VTX A8 connected to a B18 subwoofer is always pinned to the 4° position. This allows the topmost A8 cabinet to be parallel with the Array Frame.
- Page 50 VTX A8 | Rigging Manual STEPS: • Raise the suspended cluster of A8s and B18 and then align the ground cart of A8s underneath the suspended cluster. • Once the two clusters are aligned, carefully lower the suspended cluster until the front attachment points are nearly touching. Ensure that the attachment points are aligned and then lower the suspended cluster until the front attachment points come together.

VTX A8 | Rigging Manual 11.3 - DE-RIGGING THE ARRA Y The steps to de-rig a combination array are the same as s standalone A8 array. Follow the steps outlined in chapter 10 to safely dissem- ble the array. 11.4 - COMBINA TION ARRA Y SAFETY NOTE When creating combination arrays with A8 and B18 cabinets, all four connection points in line with the array frame should always be used to create a rigid and secure structure. -
Page 52: The Vtx A8 Suspension Bar
VTX A8 | Rigging Manual 12 - THE VTX A8 SUSPENSION BAR The VTX A8 SB is a lightweight suspension bar that can be used as an array frame or to implement pull-back for VTX A8 or B18 arrays. When used for pull-back, the VTX A8 SB can be attached to the bottom cabinet of an array and connected to a rear suspension point to allow for extra down-tilt, otherwise not possible by using the VTX A8 AF alone. -
Page 53: Suspension Bar Attachment Tabs
VTX A8 | Rigging Manual 12.2 - SUSPENSION BAR A TT ACHMENT T ABS The Suspension Bar is intended to be connected to the bottom or the top of a suspended array of VTX A8s or B18s. When connected at the bottom (last cabinet of an array), the array attachment tabs must be released from their storage positions in order to attach to a VTX A8 or B18 cabinet. -
Page 54: Vtx A8 Sb For Pull-Back
VTX A8 | Rigging Manual 12.3 - VTX A8 SB FOR PULL-BACK The primary role of the Suspension Bar is to be used as a pull-back attachment at the bottom of an array to support array configurations that require a significant amount of down-tilt. In this case the VTX A8 AF is used at the top of the array for the primary suspension point, with the VTX A8 SB attached to the bottom of the array and lifted with a second, rear motor point. -
Page 55: Using Two A8 Suspension Bars
VTX A8 | Rigging Manual 12.4 - USING TWO A8 SUSPENSION BARS Two VTX A8 Suspension Bars can be used for both the top and bottom of and a VTX A8 array. This configuration is helpful when the flexibility of the main Array Frame is not needed, while at the same time reducing cost and the overall weight of an array. Many perma- nent installation configurations can benefit from this arrangement. -
Page 56: When To Use A Pull-Back
VTX A8 | Rigging Manual 12.5 - WHEN TO USE A PULL-BACK The use of a pull-back is best suited when the center of gravity (CoG) of an array falls outside the footprint of the Array Frame. Typically, long curved arrays with a large down angle qualify for this condition. When this condition is true, LAC displays an error to indicate that the array frame alone cannot achieve the down angle needed for the design (LAC - Example 1). -
Page 57: Using A Single Vtx A8 Sb
VTX A8 | Rigging Manual 12.6 - USING A SINGLE VTX A8 SB The Suspension Bar can also be used as the main suspension frame. When the VTX A8 SB is used as a frame, the advantages are that the attachment is simpler, lighter and more cost effective than using a VTX A8 AF. The disadvantage of this configuration—and the main reason that this is not a recommended configuration for regular use—is that the center of gravity (CoG) of the given array must perfectly line up with the shackle attachment position on the Suspension Bar. - Page 58 VTX A8 | Rigging Manual Below is an LAC example demonstrating a good scenario where it is appropriate to use the VTX A8 SB as the main array frame. LAC Venue Example The venue geometry below calls for an array geometry that has the array CoG perfectly lined up with the rear suspension point of the top A8 enclosure (LAC - Example 4).
-
Page 59: Suspension Bar And Mixed Arrays
VTX A8 | Rigging Manual 12.6 - SUSPENSION BAR AND MIXED ARRA YS The Suspension Bar can used as a pull back for mixed arrays but not as the array frame at the top. In mixed array conditions, an array frame is always used at the top to provide the structural rigidity needed for mechanical safety. -
