Atlas SM42T User manual

Use surface-mount Atlas Sound Strategy Series loudspeaker systems where versatility and high-fidelity
sound is desired. Systems are ideal for indoor and outdoor installation, in conference rooms & classrooms,
boutiques/shops, restaurants/cafes, leisure, recreation/sports centers and houses
of worship.
All models are constructed of weather resistant materials: UV-resistant, talc impreg-
nated, polypropylene injection molded cabinets; polypropylene or treated woofer cones;
powder coated aluminum grilles and all brass hardware. In fact the SM series have
been evaluated for weather resistance by a stringent 100HR salt spray test per the
ASTM B117 standard, and passed the test with no visible corrosion or degradation
of performance.
A multi-position, C-shaped mounting bracket is included with each model at no
additional cost. Rugged construction provides optimum installation flexibility and assurance
of long-term service.
SM42T-B, SM42T-W (8Ω & 70.7V/100V)
The SM42T-B (black) and SM42T-W (white) are compact, 2-way, (8 Ohm/70.7V) weather-resistant, surface
mount speakers designed to work in a variety of applications.
System components consist of a highly efficient 4" woofer section and a dome style tweeter. Vocal and
musical clarity is optimized by the mathematically conceived, advanced design of the Atlas Sound TRX
Control WaveGuide high frequency director. The high frequency section is symmetrical (90˚H x 90˚V) for
equal coverage in both the horizontal or vertical cabinet mounting positions.
SM42T includes a 70.7V/100V transformer with screw-
driver adjustable tap settings from 2-16 watts for
70.7V/100V distributed sound applications and a
transformer bypass setting for direct coupled 8 Ohm
applications.
SM52-B, SM52-W (8Ω)
SM52T-B, SM52T-W (70.7V/100V)
The environment-resistant SM52 Series loudspeaker
systems offer quality sound reproduction and
contemporary styling in a compact enclosure.
System components consist of a highly efficient
5 1/4" woofer section and FerroFluid cooled,
titanium dome high frequency device. Vocal and
musical clarity is optimized by the Atlas Sound TRX
Control WaveGuide (90°H x 90°V). High frequency component protection is provided by the Atlas Sound
PolyGuard™ circuit.

For surface mount applications where increased output
and tighter pattern control is required the SM82 series
is a perfect choice!
System components consist of a highly efficient 8"
woofer section and 1" exit titanium compression driver.
Like other SM models the Atlas Sound TRX Control
WaveGuide high frequency director provides outstand-
ing performance with tighter, yet even sound coverage
(65°H x 65°V). High frequency component protection is
provided by the Atlas Sound PolyGuard™ circuit.
