APPLICATIONS:

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 substi-

tution 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.
