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 installations 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-purpose 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 vertical positioning. Termination is via a 12" connecting cable. Finish is light beige epoxy.

DRIVER PROTECTION: The horn loudspeaker should not be operated at frequencies 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 electrolytic capacitors may be used.
