Constant Voltage (70-Volt) Audio Systems
Audio distribution systems, especially those commonly used in department stores, warehouses, restaurants, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire. The "constant voltage" or "high impedance distribution" audio systems can be complex to understand at first, however, provides many advantages.
