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 mylar high frequency device. Vocal and musical clar-

™

ity is optimized by the mathematically conceived, advanced design of

the Atlas Sound TRX Control WaveGuide

design provides smooth, even sound coverage (90° x 90°). The high

frequency section is symmetrical, for equal coverage in both vertical

and horizontal cabinet mounting positions. High frequency component

p rotection is provided by the Atlas Sound Poly Guard

Both drivers feature low-flux-leakage designs enabling the speaker

to be used in close proximity to video monitors. For critical video

m onitoring applications, a minimum distance of 18" from the edge of the

l oudspeaker to the edge of the screen is recommended. The SM42T

includes an internally mounted, 16 Watt 70.7V / 100V line matching

transformer with screwdriver adjustable external tap selection for use in

distributed sound applications.

To withstand the harshest environments, the new Strategy Series

SM42T surface mount loudspeakers are constructed of weather

r esistant materials: UV-resistant, talc impregnated, polypropylene

i njection 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 mounting surface is strong

enough to s upport the SM42T. Care should also be taken to ensure

that the SM42T is not exposed to direct precipitation. A

hole is provided on the C-bracket to allow the SM series speaker to be

mounted on any Atlas Sound microphone stand for near-field live sound

applications. 2

SM42T to a ccommodate the Atlas Sound SMBALLMOUNT bracket or

10 Series brackets. All inserts for mounting knobs are

standard

"-20 to allow easy substitution of standard "off the shelf"

vandal proof torx head or "one-way" hardware. Input connectors include

a sealed 2-pole terminal strip capable of accepting up to two #14AWG

wires. 2, 4, 8, and 16 Watt taps are screwdriver selectable via a sealed

switch located near the input section on the rear of the cabinet. Internal

transformer may also be bypassed for 8-ohm operation via tap s elector

switch. A flush cover with wire exit hole is provided to ensure input

c onnections and tap selector switch are protected. Systems are a vailable

in Black or White finishes and can be painted to accommodate any

a rchitectural considerations.
