Horn speaker series

TOA's SC Series Paging Horn Speakers are designed for both indoor and outdoor applications. The lineup includes six models rated at 10W (SC-610 and SC-610M), 15W (SC-615 and SC-615M) and 30W (SC-630 and SC-630M).

The "M"- type models are designed for use in high-impedance (70V/100V lines) systems and standard models for low-impedance (8Ω) systems. This wide product lineup permits selection of the ideal speaker for most applications.

SC Series speakers feature newly developed diaphragms employing special heat-resistant fibers impregnated with phenolic resin to
prevent the diaphragm from absorbing moisture and changing shape. High speaker efficiency has also been realized by minimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. The aluminum foil bobbin also features excellent heat dissipation properties to resist high power inputs and ensure high speaker durability.

All speakers feature TOA's unique oval shape, which enhances excellent speech clarity. The mounting brackets and all external hardware (screws, bolts) are made of stainless steel. The horn itself is treated with 50-micron thick powder paint coating, which is about three times thicker than that of the conventional horns. All of these factors combine to ensure the speaker's excellent weatherproofing and corrosion resistance. In addition, the external horn flare is made of aluminum which is more shock-resistant than resin.

High-impedance models are equipped with an input impedance selector switch (4 steps for 100V line, and 5 steps for 70V line) which facilitates impedance settings without requiring disassembly. The switch is also equipped with an OFF position to prevent speaker damage resulting from incorrect impedance setting.
