• Easy, weather resistant connection via a 4-pole terminal block
connector

Ω
nominal system impedance
• Heavy duty stainless steel mounting bracket (included) allows for
easy installation to almost any fl at surface
• Three forged eyebolts also included for suspended installation
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.
