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

Disregard my post, because I mis-read your question. I thought that it said your polarity was different from the CD player to the preamp. Sorry.

What I'm sure is that I don't know what is going out of my CDP ;-)

my user manual of my CDP says connectors are :
1=ground
2=(+)
3=(-)
and back of my CDP connectors are explained :
1=ground
2=(-)
3=(+)

so I need to check wher is my (HOT) pin

do u understand what I mean?

sorry for my english I'm a poor frenchie guy

Have you contacted the manufacturer? 9 out of 10 times, they mis-print the manual.

You really need a 'scope to double-check this. However sometimes there is a slight DC offset voltage on pins 2 and 3 from some cd (or DAC) XLR outputs. If you have a DVM with reasonable resolution you could try and measure on a low DC volts range across pins 2 and 3 and then reverse the probes and compare. This may give you an indication as to which one is "hot".

If you try this, usual dis-claimers apply! Regards, Richard
