ELECTRO-VOICE ® 5 1. XLC Rigging System 1.1 Overview of the XLC Flying System The XLC loudspeaker systems have been designed to construct acoustic line arrays. Acoustic line arrays typically consist of independent columns of loudspeaker systems. This simplifies the rigging system. The XLC loudspeaker enclosures utilize a hinged rigging system that[...]

ELECTRO-VOICE ® 7 Specifically, this means that when the enclosures are suspended, the back of the bottom enclosure will rotate down until the pin is stopped at the end of the slot in the swing arm. This one pin will not prevent the back corners of the enclosures from coming together. When landed, the enclosures will compress together until their [...]

ELECTRO-VOICE ® 10 2. XLC Rigging and Flying Techniques 2.1 Array Considerations The XLC loudspeaker systems have been specifically designed to construct acoustic 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 c[...]

ELECTRO-VOICE ® MAKE SURE THAT THE SPRING-LOADED BUTTONS ON THE BUTTON BARS FULLY LOCK INTO THE ROUND HOLES IN THE FRONT RIGGING TUBES ON BOTH ENCLOSURES. REPEAT THIS FOR EVERY ENCLOSURE ON BOTH SIDES OF THE LINE ARRAY. Attach the top enclosure in the array to the grid, as shown in Figure 6c. (Only an XLC compatible grid can be used with an XLC ar[...]

ELECTRO-VOICE ® 12 Initially, the rear rigging will be slack as the array is lifted. As more enclosures are suspended, the rear swing arms in the top enclosures will go into tension. If it is desired to lock the enclosures at their vertical splay angles when in compression as well as in tension, the lifting should be paused so that the second quic[...]

ELECTRO-VOICE ® 3. Rigging-Strength Ratings, Safety Factors, and Special Safety Considerations 3.1 Working-Load Limit and Safety Factor Definitions The structural ratings for all of the XLC rigging components and complete loudspeaker systems are based on test results in which parts were stressed to failure. Manufacturers typically present the stru[...]

ELECTRO-VOICE ® 16 3.2 Structural Rating Overview There are two independent strength ratings that, together, give a complete description of the overall structural performance capabilities of any XLC loudspeaker system. They are defined as follows: 1. The strength of each individual rigging point; which is the combined strength of the rigging frame[...]

ELECTRO-VOICE ® 17 These guidelines provide a simplified rating for typical arrays based on the: 1. Vertical angle of each enclosure 2. Total weight of that enclosure plus all of the enclosures and rigging hung below it. 3. Angles of the force components on the front button bars and the rigging frames relative to the enclosures. 4. Angles of the f[...]

ELECTRO-VOICE ® 18 Figure 7 includes a graph of the working-load weight-versus-angle limit rating for the XLC enclo- sures. This working-load weight limit is applicable to every enclosure in an array, and includes the weight of that enclosure plus the total weight of all enclosures and rigging hardware suspended below it. The absolute enclosure an[...]

ELECTRO-VOICE ® 19 The reader should consult an experienced structural engineer to perform the complex structural analysis. WHEN SUSPENDING ANY XLC LOUDSPEAKER SYSTEM OVERHEAD, THE WORKING-LOAD LIMITS MUST NEVER BE EXCEEDED FOR EACH INDIVIDUAL RIGGING POINT, AND THE OVERALL ENCLOSURE.

ELECTRO-VOICE ® XLC-127, XLC-127+ and XLC-118 Overall Enclosure Structural-Strength Ratings The actual strength of the XLC enclosures will depend on the complex total of the combined forces from each of the rigging points acting on the enclosure as a whole and will vary with the array configuration. However, for the sake of simplicity, Electro-Voi[...]
