Page 3: Rigging-Safety Warning
Electro-Voice continually engages in testing, research and development of its loudspeaker products. As a result, the specifi- cations 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. -
Page 4: Introduction
1.0 Introduction The Electro-Voice EVF series is a group of compact two-way front-loaded full-range systems, available with 12- or 15-inch woofers, augmented by low-frequency and subwoofer systems. EVF full-range sys- tems are available in two versions. The “S” versions employ 400-watt SMX low-frequency transducers and the ND2B medium-format, 1.4-inch exit/2-inch diaphragm compression driver. - Page 5 Typical EVF and EVH systems are shown in Figure 1, with key dimensions, suspension points, weights and centers-of-gravity. Engineering data sheets for each model, containing full specifications and dimen- sional drawings, are shipped with each loudspeaker and are downloadable from the Electro-Voice Web site (www.electrovoice.com).

Page 37: Rigging-Strength Ratings And Safety Factors
When an EVF and EVH loudspeaker system is installed where local regulations only require a safety factor of 5:1, Electro-Voice insists that the WLL of the EVF and EVH rigging never be exceeded and that an 8:1 safety factor be maintained for the EVF and EVH loudspeakers. -
Page 38: Structural-Rating Overview
Determining those forces throughout a cluster requires complex mathematical calculations. Electro-Voice engineers have therefore defined a set of simplified structural-rating guidelines for both vertical and horizontal clusters that eliminates the need for complex calculations. -

Page 52: Rigging Inspection And Precautions
7.0 Rigging Inspections and Precautions Electro-Voice EVF and EVH Loudspeaker Systems: Prior to each use, inspect the enclosures for any cracks, deformations or missing or damaged components that could reduce enclosure strength. Inspect the rigging plates, tie plates and stabilizer bars between enclosures for cracks, corrosion or other defor- mations that could reduce their strength and integrity. -
