Very lucky, but need help (Tutor)

Hello I just got an almost new Lexicon MPX550 processor from a pound shop for $175 (I know it's crazy), but how can I use it with my mpc2000xl?, do I need to get 8 outs?, do I need a mixer (if so each one is good for up to $400)?, how do I connect it?

thanks for your attention

what exactly are you trying to do? You can use it when you sample and effects to your samples or you can use it when you record on mix down to and effects. You might need a mixer depending on what you are trying to do and the amount of other equipment you have. Good Luck GO BLUE.
