Rigging system
7.1
Overview of the flying system
The external rigging parts supplied with each EVA line-array module attach to internal metal
parts running top-to-bottom in each module, so that a finished array places no stress on the
wooden enclosure parts.
The rigging simplification inherent in the EVA modules is based on the final array being
assembled in a fixed manner as a single rigid structure. When flown as a single vertical column
with EVA full-range modules, EVA subwoofer modules must always be assembled at the top of
the array with no splay between them.
The EVA full-range enclosures are vertically trapezoidal: taller at the front than at the back.
One module is fastened to another bottom to top. The vertical aiming angle between the two
modules is fixed by their vertical draft angles. The draft angle is 3° for the EVA-2082S/906 and
EVA-2082S/126 long-throw modules and 10° for the EVA-2082S/920 and EVA-2082S/1220
short-throw modules, producing 6°, 13° or 20° between any two modules, depending on
which modules are attached together.

The specific selection of long- and short-throw modules and their arrangement depend on
room geometry and trim height. Electro-Voice PREVIEW Loudspeaker Software available on

Each EVA module attaches to the module below it with the supplied pair of side-mounted tie
plates. After assembling the array, attach the cosmetic end caps, one for each side of each
module, to the enclosure. The cosmetic end caps hide the structural tie plates and give a
smooth, attractive array appearance.
