Applications

Atlas Sound model AH94-12ST 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 AH94-12ST include a multiple 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 AH94-12ST 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 AH94-12ST includes a weather resistant 7 pole terminal block con- nector on the underside of the speaker for ease of hook-up. This termi- nal block includes connection points for internal 70.7V transformer with taps settings of 7.5, 15, 30, & 60 watts and 8Ω connection for trans- former bypass.
