Please help, I have an old Otari MX55 Open reel desk and the input/output connections are XLR and its' manual said Pin 1-ground, pin-reverse and pin 3-hot. I need to use XLR to RCA cables for connecting the tape desk to the amp, for the interconnect XLR-RCA cables do I have to wire pin 3 to the center pin of RCA and shorted pin 1 and 2 to the RCA jacket? I am now using the XLR-RCA cables that bought from the radio shop with pin 2 as the hot lead to the center, is this will hurt my amp and the tape desk? Since now positive is on the RCA jacket and the ground and reverse leads are on the center pin?

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.
