I would like to be able to connect my transmitter to dj 's board when we do weddings and like events. I need to some how get the mini xlr to a rca, thanks in advance for the help!

I'm not familiar with the 'Samson t3', but the transmitter's input is likely 'microphone' level.
The output from the board's RCA or other line-level output will need to be attenuated or the transmitter will distort horribly...( and no, turning down the transmitters input level will not help) This is a common issue and has been discussed a lot.. Search this forum for more info.
Sometimes, depending on the transmitter's input connector a custom cable or adapter will need to be made, a built-in 'pad' could be incorporated as well.
