Get Radio DJ to talk to Allen and Heath XB14

[tjhele]

I have an allen & heath xb 14 in my school radio station, I wanted to find out how to start cuing a track from the board, like a remote cueing feature?

Also, how can when I am playing a track cut straight out of it into sweeper?

E.g. intro plays... then i speak over background music - how do i get background music to stop after i finish to go straight into ad break?
