TOA SC-615T – 15W Paging Horn Speaker, 70/25V
Product Overview
The TOA SC-615T is a 15 W paging horn speaker with a built-in transformer for 70.7 V and 25 V constant-voltage lines, rated IP65 for outdoor and wet locations. This weatherproof paging horn speaker is designed for clear voice announcements across parking areas, loading docks, factories, and building exteriors. Multiple wattage taps let installers set output to match each zone in a distributed audio system.
Product Description
The SC-615T delivers focused, intelligible speech reproduction for paging and general announcement duty in demanding environments. Its integral line-matching transformer supports both 70.7 V and 25 V constant-voltage distribution, with selectable power taps so installers can balance loudness across many speakers on a single amplifier line. With a sound pressure level of 112 dB at one watt and one meter and a frequency response of 280 Hz to 12.5 kHz, the speaker prioritizes the vocal range where intelligibility matters most. An IP65 rating means it resists dust ingress and water jets, making it appropriate for exterior walls, covered walkways, and washdown areas, and it operates across a wide temperature range from -20 to +55 degrees Celsius. The compact housing, measuring 222 by 179 by 234 millimeters and weighing 1.3 kilograms, mounts readily on walls and structures. As a constant-voltage device, the SC-615T integrates cleanly into commercial 70/100 V paging and mass-notification systems. It is a dependable choice wherever announcements must cut through ambient noise.
