So what are 100v Line PA Systems and how do they work?

100v Line or Constant Voltage speaker systems refer to networks of loudspeakers which are connected to an audio amplifier using step-up and step-down transformers to simplify impedance calculations and to minimize power loss over the speaker cables. In short it is a high impedance system that allows for multiple loudspeaker installation from a single amplifier, the amount of speakers used will depend on the power rating of the amplifier and the power tapping options of the loudspeaker.

For Example:

15 x Wall mount speaker/ceiling speaker @ 6 watt tap setting = 90w - This would require a minimum of 100w amplifier as the total speaker power rating should not exceed 90% of the amplifiers total power rating. The speakers can be installed into multiple zones (rooms) from a single zone amplifier with the use of attenuators (volume controller) to control volume in each zone, or alternatively installed with a multi zone amplifier such as the Clever Acoustics MA 4120MP 4 Zone Mixer Amplifier.
