What are some of the major differences between 70V/100V and 8 ohm speaker systems?

  • Commercial locations typically use 70V/100V systems when more than a few pairs of speakers are required.
  • 70V/100V systems are daisy chained together, running the wire from one speaker to the next as opposed to 8-ohm speakers which are each home run back to the amplifier.
  • Multiple speakers can be used in 70V/100V systems without worrying about impedance issues which can overload and damage an 8-ohm amplifier.
  • 70V/100V systems play in mono not stereo therefore speaker placement is less critical.
  • 70V/100V systems allow for flexibility in how many speakers are run off a single amplifier by adjusting the wattage tap at each speaker.

How do I Set Up a 70-Volt Audio System?

  • The total number of speakers multiplied by the tap value cannot exceed the output power (in watts) of the 70V/100V amplifier.
  • For example, 5 speakers using 16W taps will need an amplifier with a minimum of 80W of power (5 x 16W).
  • A good rule of thumb is to select an amplifier with at least 20% greater power than the minimum. In this instance, the amplifier should have 100W of power.
