Common Design Features

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 including convention centers.

90° H X 40° V patterns (8", 12" and 15" models) work well when longer	AH5040S
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.

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

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 CP700 ampliﬁer. If transformer operation is required for long runs of smaller gauge cable please contact tech support for proper conﬁguration and

use of model AF140 auto-former. Termination is via rear mounted terminal block with a Plexiglas cover for 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 via terminal block connector sealed by a weather resistant cover. Transformer may also be bypassed for direct coupled 8 Ω operation.

12" AH models feature a version of the popular 12CXT60 compression driver coaxial loudspeaker.
