Rigging-Safety Warning
3
This document details general rigging practices appropriate to the entertainment industry, as they would
apply to the rigging of Electro-Voice EVA loudspeaker systems. It is intended to familiarize the reader
with standard rigging hardware and techniques for suspending EVA 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 EVA 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 EVA loud-
speaker 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 infor-
mation concerning materials and practices, as commonly recognized in the United States, and is believed
to be accurate at the time of 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may be superseded by local regulations.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 regula-
tions.
All specific material concerning the strength ratings, rigging techniques and safety considerations for
the EVA 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 docu-
ment and any manual update notices. All non-Electro-Voice associated hardware items necessary to rig a
complete EVA loudspeaker array (chain hoists, building or tower supports and miscellaneous mechanical
components) are the responsibility of others.
