COMPACT HIGH-EFFICIENCY 15-WATT LOUDSPEAKER SC-15

SC-15-45

FEATURES

• Value-priced, high efficiency, multi-function loudspeaker

• Precision-built 15 watt compression driver for optimum power

and intelligibility

• Environment resistant construction for long term indoor/outdoor use

• Compact size and styling enhance application flexibility

APPLICATIONS

Atlas Sound SC Series are compact, environment-resistant loudspeakers

for high-efficiency sound and signaling in intercom, sound and alarm

systems. Value-priced units are ideal as extension loudspeakers and

communication receivers. They are intended for indoor or outdoor instal-

lations in low to medium noise level environments when spot-coverage

or directional sound projection is desired. Popular applications for these

U.S.-crafted loudspeakers include retail service establishments, drive-in

facilities, industrial and manufacturing areas, warehouses, social and

recreational centers.

GENERAL DESCRIPTION

SC Series double re-entrant acoustic path loudspeakers are low-cost,

weatherproof units which reproduce voice and signal communication

with high intelligibility. Models include a built-in 15-watt compression

driver with 8 or 45-ohm impedance. Model SC-15-45 is a 45-ohm unit

for intercom uses and Model SC-15 is an 8 ohm version for multi-pur-

pose installations. All SC Series loudspeakers are equipped with a

high impact molded plastic bell, metal mounting bracket and will an

accommodate optional 70.7/25-volt transformer. They also feature a

swivel base with nut assembly for easy-to-adjust horizontal and verti-

cal positioning. Termination is via a 12" connecting cable. Finish is

light beige epoxy.

DRIVER PROTECTION: The horn loudspeaker should not be operated at frequen-

cies outside the horn cut-off. It is suggested that any program material be high-passed

at 400 Hz with a minimum slope 6dB per octave. This can be done by a low level filter

at the amplifier input or by a series capacitor at each loudspeaker. Non-polarized elec-

trolytic capacitors may be used.
