Radio One DJ Dave Pearce was there, as were Aleesha from Mis-Teeq and MC Harvey from So Solid Crew and they offered the future stars some advice.
Pearce said: "being a DJ is all about having your own style, something people can identify with. It's about the music you play and the way you play it."
More girl DJs and MCs needed
Aleesha commented on the fact that of the 500 entrants only one was a girl: "it is a very male dominated field but there are a lot of women coming through.
I always say just go for it, because whatever they (men) can do we can do better!"
But the judges didn't agree, picking a boy,17-year-old DJ IQ as the winner.
