May 3 2010 1 hello i m new at this forum i recently took over a 70 volt installation i have been. These taps are used to define the amount of power going to each speaker. So the 70 volt distributed speaker systems are mostly confined to low audio quality applications such as background music or paging. This quality dual voltage transformer equipped with connections for 70 7 volt and 25 volt line applications.

A 25v output could be used where fewer speakers are to be used and the runs of wire are not extremely long such as in a doctor s office. 100v and even 140v outputs can be found on some of these distribution amplifiers. 70v systems use transformers on the speakers that. Speaker layout wiring methods and phasing are the same for either technology and are covered on pages 70 76.

Welcome to the 70 volt wiring tutorial from skywalker. Tags pro audio speakers. You ll note that the above schematic shows colored taps on t transformer that is associated with each speaker. The pure resonance audio tm4 dual voltage transformer adapts conventional 8 ohm speakers for use with multi speaker 70 volt commercial distributed sound systems.

As shown it is easy to add the individual speaker watts together. No wiring changes to the speaker circuits are required.
