Page 4: Introduction
1.0 Introduction The Electro-Voice EVA (Expandable Vertical Array) loudspeaker systems or line-array modules represent an important step in line-array technology for small- and medium-scale fixed-installation sound reinforce- ment. The various models are designed to significantly simplify the physical assembly of a line array. Also, arrays of EVA full-range modules are designed to be powered from one amplifier channel, the necessary crossover and EQ functions accomplished with sophisticated passive networks. - Page 5 BLK or B at the very end of the complete model number and white is indicated by WHT or W at the very end of the complete model number, e.g., EVA-2082S/906-BLK and EVA-2082S/906-PIB.

The working-load limits defined by the manufacturer of any rigging component should never be exceeded. Electro-Voice bases the working-load limits of its EVA products on a minimum of an 8:1 safety factor. Other manufacturers of rigging components may base their working-load limits on safety factors other than 8:1. -

6.0 Rigging-Strength Ratings and Safety Factors (cont’) 6.6 Electro-Voice Structural-Analysis Procedures Electro-Voice maintains a structural pull-test facility in Burnsville, Minnesota USA which includes load cells with digital-electronic display and recording. The load cells are calibrated annually by an independent laboratory to a standard traceable to the United States National Bureau of Standards. This pull-test facility is capable of pulling to destruction both individual rigging components and complete loudspeaker sys- tems. -
Page 37: Rigging Inspection And Precautions
Hardware that is bent or showing signs of more than cosmetic surface corrosion should be replaced immediately. Electro-Voice EVA Grids: Prior to each use, inspect the grid side bars and spreader bars for any cracks, corrosion, missing or damaged parts or any other deformation that could reduce their strength and integ- rity. -
