The word NORMAL and XLR are confusing to most folks as they think that XLR's 
are 3 pin connectors.  Well, XLR's are made normally with 3 pins, normally 
with 4 pins and normally with 5 pins depending on the application required. 
All of these are normal.

As to wire, there's good wire and cheap wire.  You pay a lot more for good 
wire.  Star Quad cable is great for producing good RF immunity and good 

As to the length of microphone lines,  I frequently run lines in excess of 
100 ft with NO RF issues.  Of course I use very good wire and good 
installation techniques.  Most folks think that the shield should be 
connected at both ends.  Not so, just one end only.  If you need ground 
continuity then there must be a separate wire inside the shield for this 
application.  Remember, the shield is simply that, a shield.  It should not 
be a current carrying conductor.

Analog audio and Tentec forever.
