Atlas Sound T18 – 60W 70.7V Line Matching Transformer for Horn Speakers

Product Overview

The Atlas Sound T18 is a high-quality 60-watt, 70.7V line-matching transformer designed for use with compression driver horns and other high-power loudspeakers in commercial distributed audio systems. It provides 2.5, 5, 10, 20, 40, and 60-watt primary taps, with a 4, 8, or 16-ohm secondary, enabling flexible impedance matching across a wide range of speaker and amplifier combinations. The T18 is a U-frame, varnish-impregnated design that reduces line loss over long cable runs in 70V distributed systems. It is well-suited to high-noise industrial, transportation, and large-venue paging environments.

Product Description

The T18 is a line-matching transformer from Atlas Sound's T Series, built for high-power 70.7V distributed audio applications. As a varnish-impregnated U-frame transformer, it is constructed with element-resistant components that protect against moisture and environmental degradation in demanding installation environments. All terminals are clearly identified for solder connection, which supports clean, permanent wiring during installation. The 60-watt power rating makes the T18 appropriate for compression driver horns used in high-noise environments including manufacturing floors, warehouses, transportation facilities, and outdoor covered venues where output levels must overcome ambient noise. The frequency response of 60Hz to 20kHz provides full-range coverage that is compatible with both voice paging and music reinforcement applications. The secondary impedance options of 4, 8, and 16 ohms allow the integrator to match a wide variety of speaker loads. At 2 11/16" wide and 2 1/4" tall, the T18 is compact enough to mount on or near a speaker or horn enclosure. High efficiency design minimizes insertion loss, which is particularly important in long-run 70V systems where multiple speakers share a common amplifier output. The 60-month warranty reflects its intended use in permanent commercial and industrial installations.
