Rigging-Safety Warning This document details general rigging practices appropriate to the entertainment industry, as they would apply to the rigging of Electro-Voice X-Line Very Compact (XLVC) loudspeaker systems. It is intended to familiarize the reader with standard rigging hardware and techniques for suspending XLVC loudspeaker systems overhead. Only persons with the knowledge of proper hardware and safe rigging techniques should attempt to suspend any sound systems overhead. Prior to suspend

0. Introduction The X-Line Very Compact (XLVC) loudspeaker systems represent an important step in line-array technology for small- and medium-scale sound reinforcement. The individual loudspeaker drivers, acoustic lenses, acoustic waveguides, enclosures and rigging hardware were all designed specifically for the XLVC product line to not only achieve the highest acoustic output with the highest fidelity, but also to produce a precise wavefront from each element to achieve state-of-the- art line-a

1. X-Line Very Compact Rigging System 1.1 Overview of the XLVC Flying System The XLVC loudspeaker systems have been designed to construct correct acoustic line arrays. Acoustic line arrays typically consist of independent columns of loudspeaker systems that acoustically and coherently sum to radiate cylindrical wavefronts. This simplifies the rigging system. The XLVC loudspeaker enclosures utilize a hinged rigging system that makes constructing arrays easy, predictable and repeatable. This front

1.3 XLVC Rigging Accessory Details Several accessories for rigging the XLVC loudspeaker systems are shown in Figure 5. This figure includes the center of gravity and rigging dimensions for the accessories and includes sufficient information to calculate the vertical angle of XLVC enclosures that are rigged together in a column, as well as the weight distribution throughout the column. XLD GRID The XLD GRID is a grid used for suspending a column of XLD281 or XS212 loudspeaker systems overhead and

XLE GRID The XLE GRID is a grid used for suspending a column of XLE181 loudspeaker systems overhead and is shown in Figure 5b. The XLE GRID sidearms are identical to that of the XLD GRID. However, the XLE GRID spreader bars are shorter to match the width of the XLE181 loudspeaker system rigging. Figure 5b: XLE GRID Rigging Dimensions and Weights CBEAM The CBEAM, shown in Figure 5c, has two functions. It may be used a coupler beam to enable a column of XS212 systems to be hung behind a either a

Figure 5c: CBEAM Rigging Dimensions and Weights XLVC-BGK The XLVC-BGK, shown in Figure 5d, is a bottom grid kit that allows the XLD GRID to be attached to the bottom of the XLD281 loudspeaker systems or the XLE GRID to be attached to the bottom of the XLE181 loudspeaker systems. The bottom grid can then be used to pull back a column of XLVC loudspeaker systems to achieve a greater downward tilt than gravity would allow without a pull back. The top of all XLVC loudspeaker systems have hinge bars

XGS-4 The XGS-4, shown in Figure 5f, is a pair of rails that may be used to groundstack XLVC loudspeaker systems. Each rail is an L-bracket that has multiple sets of front hinge bar rigging and rear swing arm rigging that mate with the front rigging tube and rear rigging channels on the bottom XLVC loudspeaker enclosure rigging. The XGS-4 may be used to stack a single column of XLD281 systems, a single column of XLE181 systems or an XLD281 column and XS212 column combined. L-Extrusion (Right) Sw

2. XLVC Rigging and Flying Techniques 2.1 Array Considerations The XLVC loudspeaker systems have been specifically designed to construct acoustically coherant line-arrays. Line-array systems typically consist of independent columns of loudspeaker enclosures. The most common implementation would be a stereo sound reinforcement system with two columns (left and right). Additional columns of loudspeakers are sometimes added to cover different seating sections of a venue – seating areas that wrap ar
