H by 65. V (2 kHz octave band) • Excellent low frequency response provides bass you can feel • Driver complement includes a 15” cast frame woofer with a concentrically mounted 1” exit compression driver coupled to a 65. H x 65. V HF horn • Full range frequency response of 75 Hz – 14.5 kHz (±5 dB) • Easy, weather resistant connection via 4-pole terminal block connector • 8 . nominal system impedance (70.7V / 100V 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 AH6565S stadium horn, with its square coverage pattern, is ideal for down firing applications like convention centers where full range reproduction, maximum intelligibility, and high sound pressure levels are required. Other applications include football stadiums, sports arenas, baseball fields, convention centers, and auditoriums. Weather resistant construction features of the AH6565S include a multiple 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 AH6565S to allow easy mounting to almost 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 AH6565S includes a 4 pole terminal block connector on the underside of the device for easy hook-up and daisy chain wiring to other AH6565S. If 70.7V/100V operation is required the optional Atlas Sound AF140 auto- former may be used. NOTE: Due to the full range operation capabilities of the AH6565S, 70.7/100V operation is possible, but 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 amplifier dampening factor is worth the sacrifice of line loss over distance -especially if transformer insertion loss at the loudspeaker location is considered. 1601 JACK MCKAY BLVD.
