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 8Ω connection for transformer bypass.

Lastly, the AH99-8ST stands out with its wide coverage pattern and increased power handling capabilities, designed to distribute sound evenly across larger areas. This makes it an ideal choice for installations where wide dispersion and volume control are key, such as gymnasiums or large assembly halls.
