Line Voltage PA Primer

[Phil Allison]

Hi to all,

initially inspired by our resident ubergeek " Klem ", about a month ago, I
persuaded my friend Rod Elliot of ESP to put together and publish a
comprehensive discussion of the many complex issues with transformer coupled
speaker loads as used in typical voice paging systems. Aka " Line Voltage
PA " .

The result of our combined efforts may well be THE definitive article
available on the net or elsewhere on the methods, design goals and many
unseen hazards inherent in such systems.

The detailed discussion of the audio transformer saturation hazard ( and how
to defeat it in practice) it is not something either Rod or myself have
ever seen published elsewhere.

Lotta words, read them all carefully.....
