General Description (cont’):
The enclosure is constructed of wood, reinforced with internal steel
rigging straps, and coated with EVCoat
TM for durability and professional
appearance, or fiberglass for severe exposure. PI and FG versions
include gland nut input panel and stainless steel 3-layer grille. Enclosure
side panel covers conceal all suspension hardware. The unique acoustic
and integrated rigging design allows for an 8 module vertical array to be
built using a combination of modules from the entire EVA Series. With
multiple vertical and horizontal coverage angles to choose from, you
have the tools to maximize flexibility of system design, no matter what
the application or budget. The innovative input panel provides a choice
of phoenix-style connectors (included in all standard models), optional
cover plate with dual NL4 type connectors or a gland nut plate for use
with cable. The input panel also includes a provision for adding up to 9
dB of attenuation (in -3 dB steps) to an individual module as a user-
installed option.
The innovative EVA Series has been designed to be used with a single
amplifier channel per array (up to 8 elements/4 modules per array at 4
ohm load impedance), giving you the ability to have a powerful, compact
and extremely efficient vertical array system.
