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.
The reader is referred to Chapters IV and V of this manual for a detailed discussion of the structural strength ratings of the Xi-A loudspeakers and L- track rigging accessories, and information on how to safely suspend Xi-A loudspeaker systems overhead. ® ELECTRO-VOICE Xi-A Rigging Manual...
Manufacturing, Inc. (See Appendix A for details.) These assemblies, shown in Figure 2.3, have been specifically designed for optimal implementation of the Electro-Voice L-track flying systems. The GS-1B includes a double-stud, swivel-ring fitting on one end for attachment to the enclosure and a safety hook on the other end.

With grilles in place, the Xi-A subwoofer systems are indistinguishable from the large Xi-A full-range systems, allowing the option of either flying the subwoofers or stacking them on the floor, or even a combination of the two, while still preserving ® ELECTRO-VOICE Xi-A Rigging Manual...
The addition of the second enclosure causes the top cabinet to point upward. Shifting the upper attachment point of the first cabinet back, as shown in Figure 2.6b, counteracts the additional load and results in the upper cabinet pointing straight ahead ® ELECTRO-VOICE Xi-A Rigging Manual...

250 pounds at any pull angle. The working-load-limit rating of the overall enclosure is 750 pounds. Electro-Voice insists that the user must never apply a load to any Xi-A flying loudspeaker system that exceeds the working-load limit rating of either the individual rigging point or the overall enclosure.
The working-load limits discussed throughout this manual for the strength of the Electro-Voice Xi-A enclosures rigging hardware, and the GS-1B, LS-1B, LS-2B, LS-3B, RS-1B and RS-2B rigging accessories are based on an 8:1 minimum safety factor. Where local regulations require safety factors greater than 8:1, Electro-Voice insists that the user must meet the required safety factor.

The user is responsible for determining the loads on all of the mechanical components throughout the loudspeaker array, and for ensuring that the working-load limits and resulting safety factors are not exceeded. A qualified structural engineer should be consulted to evaluate the design. ® ELECTRO-VOICE Xi-A Rigging Manual...
Prior to each use, inspect the building structural supports for any cracks, deformation, broken welds, corrosion, or missing or damaged components that could reduce the structural strength. Damaged building structural supports should be replaced or repaired and re-certified by a professional engineer. ® ELECTRO-VOICE Xi-A Rigging Manual...
