Features
• Effi ciency rating of 104 dB (1 W/1 M)
• 250 watts power handling
• Maximum output of 128 dB (Rated Power @ 1 M)
• Constant directivity design offers controlled coverage of 50˚
horizontal by 40˚ vertical (2 kHz octave band)
• Excellent low frequency response down to 80 Hz (–5 dB) provides
bass you can feel
• Driver compliment includes a 15" cast frame woofer with a
concentrically mounted 1" exit compression driver coupled to a
50˚ H x 40˚ V HF horn
• Full range frequency response of 75 Hz – 17 kHz (± 5 dB)
• Easy, weather resistant connection via parallel 4 pole terminal strip
• 8 Ω nominal system impedance (70.7V operation via optional
Atlas Sound model AF140 transformer)
• Heavy duty stainless steel mounting bracket (included) allows for
easy installation to most any fl at surface
• Three forged eyebolts also included for suspended installation
Applications
Atlas Sound model AH5040S stadium horn is ideal for directional
sound distribution where full range reproduction, maximum intellig ibility,
and high sound pressure levels are required. Applications include foot-
ball stadiums, sports arenas, baseball fields, convention centers, and
auditoriums.
Weather resistant construction features of the AH5040S 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 AH5040S 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 AH5040S includes a parallel wired, weather resistant 4 pole ter-
minal block connector on the underside of the device for easy hook-up
and daisy chain wiring to other AH5040S’s. If 70.7V/100V operation
is required the optional Atlas Sound AF140 autoformer may be used.
NOTE: Due to the full range operation capabilities of the AH5040S
70.V/100V operation although possible, is discouraged. Better frequency
response and amplifier dampening 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 improvement of frequency response and ampli-
fier dampening factor is worth the sacrifice of line loss over distance
- especially if transformer insertion loss at the loudspeaker location is
considered.
