RE: XLR-RCA

Check section 3.5 starting on page 24 of the article linked below.

The XLR standard now is to have pin 2 as +, pin 3 as - and pin 1 as chassis. Before this standard was in place a lot of components had pin 2 as - and pin 3 as + which appears to be what you have. If so, you will not be able to use standard off the shelf adapters - at least without modifying them. Having the phase reversed won't hurt anything but may have audible consequences.

PS. Pay attention to where pin 1 is connected - it should be connected to the chassis, and not to the signal ground. This is discussed as "the Pin 1 Problem" in the article.
