The Crown T-170V is a single-channel constant voltage autoformer that allows a standard amplifier to drive distributed speaker systems requiring 70 V or 100 V operation. It provides impedance matching, enabling amplifiers without built-in high-voltage outputs to connect to constant voltage speaker lines. This unit is ideal for commercial audio installations including background music, paging, and multi-room audio systems. It delivers accurate sound with minimal signal loss and is compact and easy to install. Key Features: Autoformer design for matching standard amplifiers to 70 V or 100 V speaker lines Converts low-impedance amplifier outputs to high-impedance distributed speaker systems Wide frequency response from 20 Hz to 20000 Hz for accurate audio reproduction Low core loss for efficient signal transfer Compact and lightweight design for easy mounting in racks or enclosures
