What is a 70 Volt System?
A 70-volt system is the preferred choice for installations requiring multiple speakers, offering significant advantages over traditional 8-ohm systems. One of the primary benefits is simplified wiring and the ease of matching speakers with an amplifier. For instance, with a 350-watt 70V amplifier, you can connect enough speakers to approach the amplifier’s maximum wattage—whether it’s six speakers at 50 watts each or 50 speakers tapped at 6 watts each. To optimize performance, it's recommended to select an amplifier with slightly more power than the combined wattage of your speakers.
The term "tap" refers to the power settings on each speaker. For example, these speakers offer tap options of 6.3W, 12.5W, 25W, and 50W, which control the maximum power each speaker draws from the amplifier. This allows you to customize the audio output for different areas. In a restaurant, for instance, you could set dining area speakers at 5 watts, bar area speakers at 20 watts, and hallway speakers at 2.5 watts for a balanced ambiance.
Another benefit of a 70-volt system is flexibility—you can mix and match various types of 70V speakers, including ceiling speakers, in-wall speakers, and subwoofers, to meet your needs.
With a 70V setup, you can also run long stretches of speaker wire without signal loss, making it ideal for large installations.
Wiring is Simple: Connect all positive terminals of the speakers to the positive 70V terminals of the amplifier, and all negative terminals to the amplifier’s negative terminals. There's no need to worry about impedance, as power remains constant throughout the system
