AtlasIED LT-70 Impedance Matching Transformer

Optimize distributed audio and paging with the AtlasIED LT-70 impedance matching transformer, engineered to deliver reliable 70.7V line matching with minimal audio loss. This compact transformer is ideal for security, surveillance and monitoring environments where clear voice reproduction and dependable performance are critical. With a 5VA power rating, selectable primary taps of 0.5, 1, 2 and 5 watts, and an 8 ohm secondary, the LT-70 lets integrators precisely balance speaker output across zones while keeping insertion loss under 1.5 dB. Frequency response is optimized for speech intelligibility, covering 100 Hz to 10 kHz, so paging and alarm messages remain clear in PA and emergency notification systems. The small footprint makes the LT-70 a practical choice for retrofits, ceiling speaker installations and tight equipment cabinets. NDAA-compliant manufacturing means the unit meets procurement requirements for many public sector projects. Upgrade your distributed audio or security audio deployments with a dependable transformer that reduces installation complexity and preserves sound quality.
