Constant Voltage (70-Volt) Audio SystemsAudio 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. Learn how to design your own 70-volt or 25-volt loudspeaker system.
