Page 39: 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 steps below to correctly and safely suspend an array. Instructions on suspending mixed A8/B18 arrays can be found later in this document. 9.1 PRESELECT THE ANGLES STEPS: •... -
Page 40: Pre-Locking The Angles (Optional Step)
VTX A8 | Rigging Manual 9.2 PRE-LOCKING THE ANGLES (OPTIONAL STEP) This step is not required, but provides a convenient shortcut. After selecting the angles, 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 con- nection points sit at a much higher elevation enabling them to connect more easily to the flown arrays . -
Page 41: Suspend The First Stack
VTX A8 | Rigging Manual 9.3 SUSPEND THE FIRST ST ACK STEPS: • Check that all red Locking Levers are in the locked position, then engage the hoist to lift the array off the ground. As the hoist lifts, each cabinet will expand to the correct angle. As each cabinet reaches the correct inter-enclosure angle , it stops ex- panding. -
Page 42: 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 below the suspended cluster. • Once the clusters are aligned, carefully lower the suspended cluster until the front attachment points are nearly touching. Check that the attachment points are aligned, then lower the suspended cluster until the front attachment points join together. - Page 43 VTX A8 | Rigging Manual STEPS: • After the two front QRPs have been secured, lower the flown array until the two rear connection points join together. Once touching, insert the two rear QRPs to secure the clusters together. If the angle of the flown cluster is too steep (too much down- tilt) and the rear connection points are too far apart, follow the steps shown below to safely connect the clusters.
- Page 44 VTX A8 | Rigging Manual In some cases, the angle of the flown array may be too steep to fully connect to the cluster on the ground. This can happen when as- sembling 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 engage all four connection points for the array.

VTX A8 | Rigging Manual 11 - MIXED ARRA YS WITH A8 AND B18 VTX A8 cabinets are mechanically and acoustically compatible with VTX B18 single-18-inch subwoofers. All A8 suspension accessories are compatible with the VTX B18, enabling mixed arrays with VTX A8s suspended under B18 subwoofers to be created. This section of the manual covers creating mixed VTX A8/B18 arrays. - Page 51 VTX A8 | Rigging Manual With the frame properly connected, lift the B18 off the ground and disconnect the Vertical Transport cart. STEPS: • Use the electric hoists to raise the B18s off the ground. • Once suspended, remove the VT by first removing the front two QRPs and then the two at the rear. •...

Page 52: 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 first cluster of A8 cabinets can be added to the array. Note that the first VTX A8 connected to a B18 subwoofer is always pinned to the 4° position. This allows the top A8 cabinet to sit parallel with the Array Frame. - Page 53 VTX A8 | Rigging Manual Once the VT has been disconnected from the flown array of B18s, the first cluster of A8 cabinets can be added to the array. Note that the first VTX A8 connected to a B18 subwoofer is always pinned to the 4° position. This allows the top A8 cabinet to sit parallel with the Array Frame.
- Page 54 VTX A8 | Rigging Manual STEPS: • Raise the suspended cluster of A8 and B18 cabinets, then align the cart of A8s on the ground underneath the suspended cluster. • Once the clusters are aligned, carefully lower the suspended cluster until the front attachment points are nearly touching. Check that the attachment points are aligned, then lower the suspended cluster until the front attachment points join.

Page 55: Rigging The Array
VTX A8 | Rigging Manual 11.3 DE-RIGGING THE ARRA Y The steps to de-rig a mixed array are the same as for a standalone A8 array. Follow the steps in chapter 10 – Disassembling an A8 Array to safely de-rig the array. 11.4 MIXED ARRA Y SAFETY NOTE To create a rigid and secure structure when building mixed arrays with A8 and B18 cabinets, each cabinet should always use all four of the connection points corresponding to the points connecting the array to the array frame. -
Page 56: 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 enables more downtilt than is possible using the VTX A8 AF alone, by attaching it to the bottom cabinet of an array and then connecting to the suspension point for the rear of the array. -
Page 57: Vtx A8 Sb Suspension Bar Attachment Tabs
VTX A8 | Rigging Manual 12.2 VTX A8 SB SUSPENSION BAR A TT ACHMENT T ABS The VTX A8 SB Suspension Bar is designed to connect to the top or bottom of a suspended array of VTX A8s or B18s. When connected to the bottom (lowest cabinet in the array), the array attachment tabs must be released from their storage positions in order to attach to a VTX A8 or B18 cabinet. -
Page 58: Vtx A8 Sb For Pull-Back
VTX A8 | Rigging Manual 12.3 VTX A8 SB FOR PULL-BACK The primary role of the VTX A8 SB Suspension Bar is as a pull-back attachment at the bottom of an array for configurations requiring a significant amount of downtilt. In this case, the VTX A8 AF connects to the primary suspension point at the top of the array, with the VTX A8 SB mounted to the bottom of the array and lifted by a second motor point at the rear of the array. -
Page 59: Using Two A8 Suspension Bars
VTX A8 | Rigging Manual 12.4 USING TWO A8 SUSPENSION BARS Two VTX A8 SB Suspension Bars can be mounted to the top and bottom of a VTX A8 array at the same time. This configuration can reduce cost and overall array weight when the flexibility of a VTX A8 AF Array Frame is not needed. Fixed installations often benefit from this arrangement. -
Page 60: 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 common when the center of gravity (CoG) of an array falls outside the footprint of the Array Frame. Typically, long curved arrays with a large downtilt qualify for this condition. When this occurs, LAC displays an error to indicate that the array frame alone cannot achieve the down angle needed for the design (Example 1 - No pull-back). -
Page 61: Using A Single Vtx A8 Sb
VTX A8 | Rigging Manual 12.6 USING A SINGLE VTX A8 SB The VTX A8 SB Suspension Bar can also be used as the main suspension frame, but this configuration is not recommended for regular use. While the SB is simpler, lighter, and more cost-effective than using a VTX A8 AF, when using the SB the center of gravity (CoG) of the array must perfectly line up with the shackle attachment position on the suspension bar. - Page 62 VTX A8 | Rigging Manual Below is an example from LAC of a scenario appropriate to using the VTX A8 SB as the main array frame. LAC Venue Example The venue geometry in Examples 4 and 5 calls for an array design in which the array CoG is perfectly lined up with the rear suspension point of the top A8 enclosure (Example 4 - CoG with array frame).
-
Page 63: Suspension Bar And Mixed Arrays
VTX A8 | Rigging Manual 12.7 SUSPENSION BAR AND MIXED ARRA YS The VTX A8 SB can used as a pull back for mixed arrays, but not in place of an Array Frame at the top of the array. In mixed array situa- tions, an Array Frame is always used at the top to provide the structural rigidity needed for mechanical safety. -
Page 64: The Vtx A8 Mini Frame
VTX A8 | Rigging Manual 13 - THE VTX A8 MINI FRAME The VTX A8 MF Mini Frame is a lightweight, compact and inexpensive array frame used for suspending smaller VTX A8 and VTX B18 arrays. The three-piece design is comprised of two side arms and one spreader bar. The side arms connect to the cabinets, and the spreader bar can be pinned to one of the 22 pick-point positions, providing excellent tilt resolution. -

Page 67: Mini Frame Suspension Options
VTX A8 | Rigging Manual 13.4 MINI FRAME SUSPENSION OPTIONS The VTX A8 Mini Frame can be used in single-point configurations using the center shackle position of the spreader bar. Alternatively, the two side shackle positions can be used to facilitate dual-point configurations. When a single-point is used, the side shackle positions can be used for safety attachment and vice-versa. -
Page 68: Selecting Spreader-Bar Positions
VTX A8 | Rigging Manual 13.5 SELECTING SPREADER-BAR POSITIONS Each of the Mini Frame side arms includes 22 hole positions for attaching the spreader bar. The position of the spreader bar determines the overall site angle of the array. The further back the spreader bar is attached, the more down angle is generated and vice versa. The exact position of the spreader bar for a given angle is determined using Line Array Calculator 3 software. -
Page 69: Mini Frame And Rc500
VTX A8 | Rigging Manual 13.6 MINI FRAME AND RC500 The Mini Frame can be used in combination with the VTX RC500 rotating clamp. The VTX RC500 is a universal truss/pipe adapter designed for vertically suspending speaker arrays from standard truss structures or pipes. The RC500 supports arrays of up to 500 kg (1,100 lbs) and is compatible with array frames that support ½-inch shackles, such as the VTX A8 MF. -
