As a result, the specifications are subject to change without notice. It is the responsibility of the user to ensure that any Electro-Voice loudspeaker system is suspended overhead in accordance with the strength ratings, rigging techniques and safety considerations given in this document and any manual update notices. -
Page 4: Introduction
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-array performance. - Page 5 Center of Gravity (363mm) 28.58in Rear View (726mm) Top View Weight: 90 lb (40.9 kg) 20.00in (508mm) 10.00in (254mm) Center of Gravity Front View Side View (Without Grille) Figure 1c: XS212 Loudspeaker System ® ELECTRO-VOICE X-Line Very Compact Rigging Manual...

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. - Page 7 0° to 10° in 1° increments, while the XS212 enclosure may be angled from 0° to 20° in 2° increments. The angle adjustment holes are detailed in figures 4a and 4b.

Page 18: Rigging-Strength Ratings, Safety Factors, And Special Safety Considerations
The working-load limits defined by the manufacturer of any rigging component should never be exceeded. Electro-Voice bases the working-load limits of its XLVC products on a minimum of an 8:1 safety factor. Other manufacturers of rigging components may base their working-load limits on safety factors other than 8:1. -
Page 19: Structural Rating Overview
3.3 Simplified Structural-Rating Guidelines Electro-Voice engineers have defined a set of simplified structural-rating guidelines that will en- able a rigger to immediately evaluate the safety of an XLVC system on site without having to make complex force-distribution calculations. A combination of destructive testing and computer modeling were used to analyze the complex forces throughout arrays. - Page 20 3. Angles of the force components on the front hinge bars and rigging tubes relative to the enclosures. 4. Angles of the force components on the rear swing arms, quick-release pins and rigging channels relative to the enclosures.

- Page 21 However, in arrays where a pull-up grid is used to achieve substantial downward angles, it is possible that a lower enclosure could be the limiting factor. ® ELECTRO-VOICE X-Line Very Compact Rigging Manual...

However, for the sake of simplicity, Electro-Voice chooses to define the work- ing-load limit of the overall enclosures as the sum total of the weight of that enclosure plus the weight of all of the enclosures and rigging hardware suspended below. -
Page 27: Electro-Voice Structural-Analysis Procedures
3.6 Electro-Voice Structural-Analysis Procedures Electro-Voice maintains a structural pull-test facility in Burnsville, Minnesota USA which includes load cells with digital-electronic display and recording. The load cells are calibrated annually by an independent laboratory to a standard traceable to the United States National Bureau of Standards. -
Page 28: Rigging Inspection And Precautions
Never exceed the limitations or maximum recommended load for the XLVC systems. Electro-Voice XLVC Front Rigging Hinge Bar Assemblies: Prior to each use, inspect the front rigging hinge bars and the front rigging tubes for any cracks, burrs, deformations, corrosion or missing or damaged components that could reduce hinge bar assembly strength. - Page 29 Replace any damaged mechanical components. Never exceed the limitations or maximum recommended load for the mechanical components. ® ELECTRO-VOICE X-Line Very Compact Rigging Manual...
