Use surface-mount Atlas Sound SM52T Series loudspeaker systems
for commercial, professional and residential applications or where
high-fidelity sound and weather-resistance is desired. Full-range
frequency response makes these systems ideal for indoor and outdoor
installation, in monaural and stereo foreground or background music
systems, and for applications in boutiques/shops, restaurants/cafes,
leisure, recreation/sports centers and houses of worship. Multi-position,
C-shaped mounting bracket and rugged construction provide optimum
installation flexibility and assurance of long-term service.

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 is optimized by the mathematically conceived,
advanced design of the Atlas Sound TRX Control WaveGuide high
frequency director. This design provides smooth, even sound coverage
(90˚H x 90˚V). The high frequency section is symmetrical, for equal
coverage in both vertical and horizontal cabinet mounting positions.
High frequency component protection is provided by the Atlas Sound
PolyGuard protection circuit. The SM52T includes an internally mounted
30 Watt 70.7V/100V line matching transformer with screwdriver adjustable
tap selection for use in distributed sound applications.
To withstand the harshest environments, the new Strategy Series
SM52T surface mount loudspeakers are constructed of weather
resistant materials: UV-resistant, talc impregnated, polypropylene
injection molded cabinets; polypropylene 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.

Care should be taken to ensure that the chosen fixing point is strong
enough to support the SM52T. Care should also be taken to ensure
that the SM52T is not exposed to direct precipitation. A 5⁄8"-27 threaded
hole is provided on the C-bracket to allow the SM52T series speaker
to be mounted on any Atlas Sound microphone stand for near-field live
sound applications. 23⁄8" OC brass inserts are also provided on the rear
of the SM52T to accommodate OMNIMOUNT™ 25 series brackets.
All inserts for mounting knobs are standard 1⁄4"-20 to allow easy substitution of off-the-shlelf 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 (2) #14AWG cable. .94, 1.9, 3.7,
7.5, 15, and 30 watt taps 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 can be painted
to accommodate any architectural considerations.
