Ah Series Stadium Loudspeakers - Atlas AH5040S Brochure

The AH Series Stadium Loudspeakers offer the most often requested coverage patterns while providing excellent
intelligibility for the most challenging environments including large auditoriums, sport fields.
With a complete family of 8", 12", and 15" 2-way systems, designers and specifiers can select models for whatever
SPL is required with the peace of mind that all units will provide outstanding pattern control.
90° H X 90° V models (8" and 12" models only) are suggested for shorter loudspeaker to listener distances and/or
wider coverage requirements such as bleacher seating where the speaker may be in close proximity to the crowd.
65° H X 65° V (8", 12" and 15" models) square coverage pattern models are perfect for down-firing applications includ-
ing convention centers.
90° H X 40° V patterns (8", 12" and 15" models) work well when longer speaker to listener distances require a tighter
vertical coverage pattern. 15" AH series models offer an even slightly tighter pattern of 50° H X 40° V. This device
is often mounted atop football field press boxes with the device aimed at the visitor side in conjunction with wider
coverage pattern models to cover the home side bleachers.
Common Design Features:
AH66-8ST
Multiple stainless steel mesh screens protect internal drivers from weather and pest damage. A primary rodent
screen provides protection for all components, a secondary screen resides between the high frequency horn and the
driver, and a third perforated screen protects the woofer.
Heavy-duty stainless steel mounting brackets are included with all models and three dropforge eyebolts are also
included for overhead suspension (use only load-rated & approved hardware). For light pole mounting Atlas Sound
also distributes matching mounting accessories from Allen Products. (see next page).
15" models AH9040S,
sion low frequency woofer and a concentrically mounted 1" exit compression driver. A well-designed, highly efficient
internal passive crossover network ensures proper transition between the two drivers, which collectively provide
AH94-8ST
frequency response from 75 Hz – 14.5 kHz (±5 dB).
With an efficiency rating in excess of 102 dB (1 W / 1 M), the 15" AH Series is a perfect choice for high-energy music
playback at sporting events and extended range speech reinforcement for large venue emergency notification. The
8 Ω rating allows maximum low frequency response and is a good match with Atlas Sound model
transformer operation is required for long runs of smaller gauge cable please contact tech support for proper configu-
ration and use of model
weather resistance.
The 8" & 12" 2-way models are perfect for applications where space considerations will not allow installation of the
larger 15" 2-way models. All 8" & 12" models include a 60 watt, 70.7V / 100V internal transformer which is accessed
AH99-8ST
via terminal block connector sealed by a weather resistant cover. Transformer may also be bypassed for direct coupled
8 Ω operation.
