Applications
Atlas Sound model AH66-8ST 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 AH66-8ST include a
multiple screen configuration to prevent moisture from damaging inter-
nal 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 8” cast frame
woofer.
Installation
A heavy-duty stainless steel "C" style mounting bracket is included with
the AH66-8ST to allow easy mounting to most any flat surface. Three
drop forged 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 AH66-ST includes a weather resistant 7 pole terminal block connec-
tor on the underside of the speaker for ease of hook-up. This terminal
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.
