To remove the Xvsl linking strap, grasp the locking-pin knob and pull out while app[...]

ELECTRO-VOICE ® 16 Xvsf Rigging Fitting: Two Xvsf rigging fittings can be used to attach the front of an X-Line enclosure directly to a building structure or to a grid assembly that is not compatible with the X-Line rigging track. The fitting is a proprietary triple-stud fitting that has a large steel locating plunger. The plunger not only locates[...]

ELECTRO-VOICE ® ALWAYS CHECK TO MAKE SURE THAT THE PULL-UP-BAR HINGE BASES ARE INSTALLED WITH THE CORRECT ORIENTATION WITH THE HINGES AT THE OUTSIDE EDGES OF THE TRACK. ALWAYS CHECK TO MAKE SURE THE PULL-UP-BAR HINGE BASES ARE SECURELY LOCKED INTO THE TRACK, AND THAT THE LOCKING PINS ARE FULLY ENGAGED IN THE TRACK BEFORE LIFTING ANY LOUDSPEAKER EN[...]

ELECTRO-VOICE ® The grid also has rigging track on the middle crossbar that runs side to side that matches the track on the rear of the enclosures. Either the Electro-Voice Xvhg grid hinge or the Xvhl linking hinge may be used to attach the rear of the top box to the grid. There is a pad eye on the bottom of the rear crossbar of the grid that may [...]

ELECTRO-VOICE ® 2. X-Line Rigging and Flying Techniques 2.1 Array Considerations The X-Line loudspeaker systems have been specifically designed to construct acoustic line- arrays. Line-array systems typically consist of independent columns of loudspeaker systems. The most common implementation would be a stereo sound reinforcement system with two [...]

ELECTRO-VOICE ® The rigging straps are shipped from the factory with chain connected in the A position on the fittings on both ends. (This would be denoted as an A-A length.) When the chain is connected in the B position on both fittings (known as the B-B length), the strap is 0.50 inches longer than when connected in the ?[...]

ELECTRO-VOICE ® In this document and in the software modeling program, the front rigging fitting attachment locations are denoted by the number of holes showing in the rigging track once a rigging strap is installed. On each side of the enclosures at the front, there is a pin in the middle of the rigging track that is used to secure the Fron[...]

ELECTRO-VOICE ® 2.4 Rigging an Array with Boxes Using X-Line Dollies Three dollies are available for transporting the X-Line loudspeaker systems. The actual array rigging technique will vary depending on which dollies are used to transport the systems. The Bottom Stacking Dolly can be used with the rectangular loudspeaker enclosures (Xvls, Xsub). [...]

ELECTRO-VOICE ® Figure 9: Flying with Stacking Dollies 23 Step 4: Land the suspended array on top of the next stack. Attach the rear hinges between the two stacks. Attach rigging chain at the front between the two stacks to achive the desired vertical angles. Step 3: Roll another stack of boxes into position under the suspended array. Attach riggi[...]

ELECTRO-VOICE ® Figure 10: Flying with Front Dollies The two boxes must be held parallel during the installation of the rigging hinge. If there is a slight vertical misalignment that causes the hinge to bind during installation, either the suspended box or the box on the dolly may be manually lifted to facilitate the hinge installation. Once both [...]

ELECTRO-VOICE ® Once again, the array is lifted until the box on the Front Dolly is no longer contacting the ground and the dolly is removed from the box. At this point, the next to last box is manually lifted and the front Xvsl linking straps are attached between the box next to the bottom and the box above it. This process is repeated as necessa[...]

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 X-Line rigging components and complete loudspeaker systems are based on test results in which parts were stressed to failure. Manufacturers typically present the [...]

ELECTRO-VOICE ® The array designer must be aware of the working-load limit ratings and the loads being applied to the individual rigging points and the overall enclosure. An X-Line loudspeaker system is only as strong as its weakest link. It is usually the case that one of the working-load limits will be approached sooner than the other. WHEN SUSP[...]

ELECTRO-VOICE ® Figure 11: Simplified Rating Guidelines Figure 11 includes a graph of the working-load weight-versus-angle limit rating for the X-Line enclosures. 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 suspen[...]

ELECTRO-VOICE ® In addition, the guidelines in Figure 11 include a side-to-side angle limit for the Xvhg grid hinges and the Xvhp pickup hinges. Side-to-side angle limits are not necessary for the Xvhl linking hinges because side-to-side angles are impossible to achieve if the top rigging is within its limits. Front- to-back limits are not necessa[...]

ELECTRO-VOICE ® 3.4 Complex Structural-Rating Analysis For a complete structural-rating analysis, the forces in each individual piece of rigging hardware throughout the X-Line system must be determined, as well as the forces on each enclosure. Determining these forces requires complex mathematical calculations. All of these forces must then be com[...]
