Use surface-mount Atlas Sound SM42T-B and SM42T-WH loudspeaker

systems for commercial, professional, and residential applications or

where high-fidelity sound and weather-resistance are desired. Full-

range frequency response makes these systems ideal for indoor or

outdoor installations, in monaural and stereo foreground or background

music systems, and for applications in boutiques / shops, restaurants /

cafes, corporate AV applications 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

Architect & Engineer Specifications

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 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° x 90°). 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 Poly Guard™ protection circuit.

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

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

monitoring applications, a minimum distance of 18" from the edge of the

loudspeaker to the edge of the screen is recommended. The SM42T-B

and SM42T-WH 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-B and SM42T-WH 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 mounting surface is strong enough

to support the SM42T-B and SM42T-WH. Care should also be taken

to ensure that the SM42T-B and SM42T-WH is not exposed to direct

precipitation. A 5⁄8"-27 threaded 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. 23⁄8" OC brass inserts are also

provided on the rear of the SM42T-B and SM42T-WH to accommodate

the Atlas Sound SMBALLMOUNT bracket or OMNIMOUNT™ 10 Series

brackets. All inserts for mounting knobs are standard 1⁄4"-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 selector switch. A flush cover with

wire exit hole is provided to ensure input connections and tap selector

switch are protected. Systems are available in Black or White finishes

and can be painted to accommodate any architectural considerations.

The indoor/outdoor mini-loudspeaker system shall be Atlas Sound

Model SM42T-___ (B or WH) or approved equal. Assemblies shall

consist of two-way woofer and tweeter within environment-resistant

housings. Enclosure shall be constructed of paintable UV-resistant, talc

impregnated, polypropylene injection molded plastic finished in black

(SM42T-B) or white (SM42T-WH). Each unit shall include a stamped

powder coated aluminum grille and removable C-shaped mounting

bracket. All hardware inserts shall be brass and threaded 1⁄4"-20. The

16 Watt RMS system shall have a 4" (102mm) woofer, constructed

of reinforced polypropylene, and a 1" (25mm) Ferrofluid tweeter. The

dividing network crossover frequency shall be 4kHz. The dividing network

shall include protection circuits for the high-frequency component.

Each unit shall include an internally mounted 16 Watt 70.7V / 100V line

matching transformer for use in distributed sound applications. Wattage

taps shall be screwdriver selectable via a sealed switch located near the

input section. Wattage taps shall be 2, 4, 8, &16 Watts @ 70.7V. The

loudspeaker system shall meet the following performance criteria: Power

handling: 16 Watts RMS. Frequency response: 115Hz – 16kHz (±5dB).

Sensitivity shall be 88dB SPL at one watt, 85Hz – 16kHz measured at

a distance of one meter on axis. Impedance shall be 8Ω nominal. Input

connectors shall include a two-pole barrier strip capable of accepting up

to two #14AWG cables. A cover with wire exit hole shall be provided to

protect the input connectors. The loudspeaker system shall exhibit no

performance or cosmetic degradation after a 100–hour salt spray test per

ASTM B117 The unit shall be 7" (178mm) high, 5" (127mm) wide, and

515⁄16" (151mm) deep.
