X-Array™ Loudspeaker Systems
RIGGING-SAFETY WARNING
This document details general rigging practices appropriate to the sound industry, as they would apply
to the rigging of Electro-Voice X-Array™ loudspeaker systems. It is intended to familiarize the reader
with standard rigging hardware and techniques for suspending X-Array™ loudspeaker systems over-
head. 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 X-Array™ 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 recom-
mended in this manual are, of necessity, in general terms to accommodate the many variations in loud-
speaker arrays and rigging configurations. As such, the user is expressly responsible for the safety of all
specific X-Array™ loudspeaker-array designs and rigging configurations as implemented in practice.
All of 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and practices may be superseded by local regulations.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
X-Array™ 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 develop-
ment 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 over-
head 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 X-Array™ loudspeaker array (grids, chain hoists, building or tower supports and mis-
cellaneous mechanical components) are the responsibility of others.
