Product Overview
The TOA SC-610T is a 10 W paging horn speaker built for clear voice announcements across outdoor and high-noise commercial areas. With a built-in matching transformer, this 70V paging horn speaker connects directly to the 25 V and 70.7 V constant-voltage distribution lines used in large facilities. Its IP65-rated weatherproof housing makes it a reliable commercial PA horn speaker for loading docks, parking structures, and exterior walkways. The compact aluminum horn focuses output where intelligibility matters most.
Product Description

The SC-610T is designed for public address and paging where speech must cut through ambient noise. A compression driver with a phenolic diaphragm resists heat and moisture, supporting dependable operation in demanding environments. The integral matching transformer offers selectable power taps, so installers can balance loudness across many speakers on a single 70.7 V or 25 V line. Distributed audio designers favor constant-voltage wiring like this to run long cable distances with minimal loss and to add or rebalance speakers without re-engineering the system. The IP65 rating means the horn withstands dust and driving rain, and the rated operating range covers cold and hot climates alike. The aluminum horn flare and corrosion-resistant hardware stand up to outdoor exposure over time. Typical deployments include industrial yards, transit platforms, and building exteriors that need general paging and tone signaling. The result is a rugged, intelligible speaker that integrates easily into existing commercial PA infrastructure.
