APPLICATIONS
Use surface-mount Atlas Sound SM42T 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, 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
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 film 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 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 inches from the edge of the
loudspeaker to the edge of the CRT 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 with stand 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 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. 2-3/8" OC brass inserts are also provided on the rear of the
SM42T-B
