how can I find the polarity out from my XLR

hi,

I've a little problem ;-(
I'd like do check what are the polarities out of the pin 2 & 3 of my XLR.

why ?
because the User manual of my cd player says
1=ground
2=(+)
3=(-)
and at the back of my cd player it's wrote
1=ground
2=(-)
3=(+)

how can I do to check exactly "where is" the (+) or (hot) pin

thanks for your help

Try changing your speaker cable connections at the amp. Move the (+) to the (-) and vice versa.

If the sound improves substantially, then your XLR connections (or some other connection) are reversed polarity.

As I recall, the earliest version of the Sony SCD-1 had pin 3 hot, but they did come out with a later version. One of the changes was to make pin 2 hot.
