Installation
A heavy-duty stainless steel “C” style mounting bracket is included with
the AH66-12T-BSG 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 AH66-12T-BSG includes a weather resistant 7 pole terminal block
connector on the underside of the speaker for ease of hook-up. This
terminal block includes connection points for internal 70.7V transformer
with taps settings of 7.5, 15, 30, and 60 watts and an 8Ω connection for
transformer bypass.

Applications
Atlas Sound model AH66-12T-BSG stadium horn is ideal for directional
sound distribution where full range reproduction, maximum intelligibility,
and high sound pressure levels are required. Applications include
football stadiums, sports arenas, baseball fields, convention centers,
and auditoriums.
AH66-12T-BSG
Weather resistant construction features of the AH66-12T-BSG 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 12" cast frame woofer.

Loudspeaker shall be Atlas Sound Model AH66-12T-BSG or approved equal.
The loudspeaker system shall be a horn-loaded, 2-way design with a 12"
paper cone and moisture resistant coating.
The loudspeaker system shall include a 12", horn loaded, cast frame
woofer and an integral, concentrically mounted 1" exit compression
driver coupled to a constant directivity high frequency horn. The three
pole (18dB/octave) dividing network shall have a crossover frequency of
1.8kHz. The dividing network shall include a poly switch protection circuit
for the high-frequency component.
The loudspeaker system shall be capable of providing a sound dispersion
angle of 65˚ horizontal by 65˚ vertical in the 2kHz octave band.
Rated power shall be 200 watts RMS based on EIA Standard RS-426B.*
Enclosure shall be UV-resistant, low pressure injection molded fiberglass
and shall include a 3 stage multiple mesh filter system for weather and
rodent resistance: to include a 20-gauge perforated aluminum screen on
front mouth assembly, a 100 x 100 weave stainless steel mesh between
HF horn and HF driver and a 100 x 100 weave stainless steel mesh over
12" woofer. The loudspeaker shall include a stamped and formed, 2mm
stainless steel powder coated mounting bracket assembly for surface
mounting and three M8 drop forged eyebolts for suspension mounting
two at the front and one at the rear to allow the speaker system to be
suspended and aimed using rated wire rope.
Sensitivity shall be 101dB SPL (80Hz – 15kHz in 1⁄3 octave bands)
measured at a distance of 1 meter on axis with a 1 watt input half
space (2.83V).
Overall frequency response shall be 80Hz – 15kHz (±5dB).
The input section located on the bottom rear of the loudspeaker shall be
via 7 position screw down terminal strip internally configured to allow
input to an internally mounted 70.7V transformer with 7.5, 15, 30, & 60
watt taps and a by-pass jumper for direct coupled to the speaker for
nominal 8Ω operation. The system connections shall be protected from
the elements by a screw affixed weather resistant cover.
