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
™
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
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
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. Care should also be taken to ensure
that the SM42T is not exposed to direct precipitation. A

"-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. 2

SM42T to accommodate 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 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.
