Rigging-Safety Warning - Electro-Voice Xi-A Series Manual

0. Rigging-Safety Warning

This document details general rigging practices appropriate to the entertainment industry, as they
would apply to the rigging of Electro-Voice Xi-A loudspeaker systems. It is intended to familiarize
the reader with standard rigging hardware and techniques for suspending Xi-A 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 suspending any
Electro-Voice Xi-A loudspeaker systems overhead, it is essential that the user be familiar with the
strength ratings, rigging techniques and special safety considerations outlined in this manual. The
rigging techniques and practices recommended in this manual are, of necessity, in general terms
to accommodate the many variations in loudspeaker arrays and rigging configurations. As such,
the user is expressly responsible for the safety of all specific Xi-A loudspeaker array designs and
rigging configurations as implemented in practice.
All the general rigging material contained in this manual is based on the best available
engineering information concerning materials and practices, as commonly recognized in the
United States, and is believed to be accurate at the time of the original printing. As such, the
information may not be directly applicable in other countries. Furthermore, the regulations and
requirements governing rigging hardware and practices may be superseded by local regulations.
It is the responsibility of the user to ensure that any Electro-Voice loudspeaker system is
suspended overhead in accordance with all current federal, state and local regulations.
All specific material concerning the strength ratings, rigging techniques and safety considerations
for the Xi-A loudspeaker systems is based on the best available engineering information
concerning the use and limitations of the products. Electro-Voice continually engages in testing,
research and development of its loudspeaker products. 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. All
non-Electro-Voice associated hardware items necessary to rig a complete Xi-A loudspeaker array
(grids, chain hoists, building or tower supports and miscellaneous mechanical components) are
the responsibility of others.
