Applications
Atlas Sound model AH66-15-BSG 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 AH66-15-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 15”
cast frame woofer.
Installation
A heavy-duty stainless steel “C” style mounting bracket is included with
the AH66-15-BSG 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 AH66-15-BSG includes a 4 pole terminal block connector on the
underside of the device for easy hook-up and daisy chain wiring to other
AH66-15-BSG. 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 AH66-15-BSG,
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.
