RE: arsclist question about XLR/RCA connections, pads, etc.

["Richard L. Hess" <ArcLists@xxxxxxxxxxxxxxx>]

To avoid some confusion.

In the US 120/240 power is referred to as SINGLE PHASE. It is derived from 
ONE leg of a three-phase distribution system in MOST locations. However, at 
least some locations provide 120/208--still called SINGLE PHASE by 
electricians even though it's really two phases of a three-phase system.

There are some variants like 240V Delta with one side center tapped to 
provide 120-0-120 plus a 208V leg but let this not confuse you.

Also, most balanced circuits today are high-Z. See the Voltage Audio 
distribution paper I gave at the AES convention in NYC in 1980. I know of 
few power-matched installations being built.

There are MANY myths out there. Make sure after you do something that it 
works <smile>. Even one author of a book confided in me that he'd write it 
differently today than when he wrote it--but there is no update, so people 
are still learning the wrong things!

Cheers,

Richard
