Altec Lansing 15067
A high-power autotransformer designed for flexible impedance and line voltage matching in professional audio systems
Overview
The Altec Lansing Model 15067 Autoformer is a professional audio autotransformer built to deliver reliable performance in distributed speaker systems. Designed for maximum flexibility, it supports a wide range of impedances and line voltages, making it suitable for use with both 70 V and 140 V lines. With a 150-watt power rating, the unit is engineered to minimize insertion loss while maintaining signal integrity across long cable runs. Its robust design centers around a large core volume, contributing to stable operation under demanding conditions.
