Applications
Atlas Sound model AH99-12ST stadium horn is ideal for directional
sound distribution where full range reproduction, maximum intelligibility,
and high sound pressure levels are required. Applications include football
stadiums, sports arenas, baseball fields, convention centers, and audito-
riums.
Weather resistant construction features of the AH99-12ST include a mul-
tiple screen configuration to prevent moisture from damaging internal
components.
A perforated aluminum screen covers the large horn mouth, a secondary
screen is in place forward of the high frequency driver, and a third tightly
perforated screen protects the 12" cast frame woofer.
Installation
A heavy-duty stainless steel "C" style mounting bracket is included with
the AH99-12ST to allow easy mounting to most any flat surface. Three
drop forge eyebolts are also pre-installed (2-front of horn plus 1-rear for
"pull-up") for suspension mounting via load rated wire rope. (Use caution
when suspending any object overhead. Refer to installation manual for
more details).
The AH948-ST includes a weather resistant 7 pole terminal block con-
nector on the underside of the speaker for ease of hook-up. This ter-
minal block includes connection points for internal 70.7V transformer
with taps settings of 7.5, 15, 30, and 60 watts and 8 Ω connection for
transformer bypass.
