Resources Constant Voltage (70-Volt) Audio Systems For Beginners High-Impedance Loudspeaker Distribution Audio distribution systems, especially those commonly used in department stores, warehouses, around race tracks, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire.
70 VOLT SPEAKER WIRING LIMITATIONS CHART70 VOLT SPEAKER WIRING LIMITATIONS CHART Instructions: Determine the combined output in watts for all speakers on a line. Find that value at the bottom of the chart. Follow the nearest vertical line up to its intersection with a diagonal wire size line. Follow the horizontal line nearest the intersection to the left
Speaker Wiring Often used when wiring PA systems in buildings, using hundreds of speakers. Often used when wiring outdoor PA systems using 'all weather horns'; ie. sporting events, sales areas, car lots, etc. Some disadvantages of 70 Volt systems: Low power (typically 10 watts or less) per speaker. Pro-Audio systems may have 100 to 500 watts per individual ...
What Is a 70 Volt Sound System & What Is It Used For?• Generally speaking, 70 Volt Systems are much more cost efficient than an 8 Ohm speaker system when dealing with volume installation of speakers. • 70 Volt Systems are easier to design than 8 Ohm speaker systems. The impedance does not have to be matched throughout the 70 Volt system as it would on an 8 Ohm based system.
