AFC200 – 200-Watt 70V/100V Line Autoformer for Constant Voltage Audio Systems
The AFC200 is a high-performance 200-watt 70V/100V line autoformer designed for professional constant voltage audio distribution systems. Ideal for commercial sound applications, it steps down 70V or 100V audio signals to match 4 or 8-ohm loudspeakers, ensuring optimal impedance matching and efficient power transfer.
With four output power taps (25W, 50W, 100W, 200W), the AFC200 allows precise control over speaker volume across different zones or speaker types. It features low insertion loss (1 dB) and delivers excellent low-frequency response from 70 Hz to 16 kHz, making it perfect for full-range audio systems in distributed environments.
The AFC200 is built with a high-permeability iron core for enhanced power handling and durability. Installation is flexible thanks to dual mounting tabs and color-coded 18 AWG stripped leads for easy connection via terminal strips, solder, or wire nuts.
