Applications include football stadiums, sports arenas, baseball fields, convention centers, and auditoriums. Weather resistant construction features of the AH94-8ST 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 8" cast frame woofer. Installation A heavy-duty stainless steel "C" style mounting bracket is included with the AH94-8ST 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 AH94-8ST includes a weather resistant 7 pole terminal block connector 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, & 60 watts and 8 . connection for transformer bypass. 1601 JACK MCKAY BLVD.
