Atlas Sound LT70 – General Purpose 70.7V Transformer 5W
Product Overview
The Atlas Sound LT70 is a compact 70.7V line matching transformer designed for use in commercial distributed audio systems. It provides economical impedance matching between 70.7-volt amplifier lines and 8-ohm loudspeakers, making it a practical component for background music, paging, and commercial PA installations. With selectable power taps and low insertion loss, the LT70 is a reliable choice for integrators building or expanding 70V audio systems.
Product Description
The Atlas Sound LT70 general purpose transformer delivers straightforward 70.7-volt line matching for standard speaker installations. It features four primary watt taps — 0.5W, 1W, 2W, and 5W — providing flexibility when distributing amplifier power across multiple speakers on a single 70V line. Secondary impedance is 8 ohms, making it compatible with the majority of commercial loudspeaker drivers used in distributed audio applications. Insertion loss does not exceed 1.5dB, preserving audio quality across the signal chain. Frequency response is rated at ±1.5dB from 100Hz to 10kHz, covering the full range needed for voice and music reproduction in commercial environments. The transformer's compact footprint allows it to be mounted directly to speaker baffles or inside back boxes without consuming excessive space. Its simple design reduces installation time and minimizes points of failure in large multi-speaker systems. The LT70 carries a 60-month warranty and is stocked in quantity for commercial AV contractors.
