General Description
Environment-resistant SM Series loudspeaker systems offer quality
sound reproduction and contemporary styling in a compact enclosure.
System components consist of a highly efficient woofer section and
FerroFluid cooled, titanium dome high frequency device. Vocal and
musical clarity are optimized by the mathematically conceived, advanced
design of the Atlas Sound TRX Control WaveGuide
™ high frequency
director. This design provides smooth, even sound coverage (65˚H x
65˚V). The high frequency section is symmetrical, for equal coverage
in both vertical and horizontal cabinet mounting positions. The Atlas
Sound PolyGuard
™ protection circuit provides high frequency component
protection. To withstand the harshest environments, the Strategy Series
SM82T surface mount loudspeakers are constructed of weather resistant
materials: UV-resistant, talc impregnated, polypropylene injection
molded cabinets; HYCONE Treated Paper woofer cones; powder coated
aluminum grilles and all brass hardware. The Strategy Series speaker
systems include a versatile, yet simple, C-bracket designed to provide
easy vertical or horizontal installation on just about any surface. A
5 ⁄
8
"-27
threaded hole is provided on the C-bracket to allow the SM82T speaker
to be mounted on any Atlas Sound microphone stand for near-field live
sound applications. Four, 4
1 ⁄
4
" x 2" OC brass inserts are also provided
on the rear of the SM82T to accommodate OMNIMOUNT ™ 30 series
brackets. (Model 30.0 WB recommended for wall mounting)
All inserts for mounting knobs are standard 1 ⁄
4
"–20 to allow easy
substitution of off-the-shelf vandal-proof torx head or “one-way”
hardware. Input connectors include a two pole barrier strip with wire
capture “caps” capable of accepting up to two #16AWG cables. 0.94,
1.9, 3.7, 7.5, 15, 30 and 60 watt taps, plus a transformer bypass setting
for direct coupled 8Ω operation are screwdriver selectable via a sealed
switch located near the input section on the rear of the cabinet. A
tongue-in-groove cover with rubber wire exit grommet is provided to
protect the input connections and transformer switch assembly from
moisture. Systems are available in black or white and may be painted to
accommodate any architectural considerations.
Installation Considerations:
Care should be taken to ensure that the chosen mounting surface
is strong enough to support the SM82T.Under eave installation is
recommended to ensure that the SM82T is not exposed to direct
precipitation.
