AH9040S

Applications

Atlas Sound model AH9040S stadium horn is ideal for shorter throw and

wide coverage 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 AH9040S 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 15" cast frame

woofer.

Installation

A heavy-duty stainless steel "C" style mounting bracket is included with

the AH9040S 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 aircraft cable. (Use

caution when suspending any object overhead. Refer to the installation

manual for more details).

The AH9040S includes a 4 pole terminal block, weather resistant con-

nector on the underside of the device for easy hook-up and daisy chain

wiring to other AH9040S. If 70.7/100V operation is required, the optional

Atlas Sound AF140 autoformer may be used. NOTE: Due to the full

range operation capabilities of the AH9040S 70.7/100V operation is pos-

sible, but discouraged. Better frequency response and amplifier dampen-

ing factor can be realized by using large gauge (#10 to #12) home runs

and series/parallel hook-up wiring at the head end location with direct

coupled, low impedance amplifiers. Generally speaking, this improve-

ment of frequency response and amplifier dampening factor is worth the

sacrifice of line loss over distance - especially if transformer insertion

loss at the loudspeaker location is considered.
