microphone and dj control instinct

hi, 
i have dj control instinct and i have a question: if i want to connect a microphone, how can i do it??? i must buy a mixer? 
thanks 

Indeed, the DJ Instinct does not include a microphon input.

For what purpose do you want to use the microphone ? Would it be to adress the audience or for recording ?
 

Thanks for reply. I need for audience.

Then yes, you could use a small mixer with a microphone input, such as this one:

Or use the microphone input of the PA system (if one is present obviously). 

Thanks a lot! 

how do u connect one for recording?

As stated previously, the DJControl Instinct does not include a microphone input, so you would need another audio interface, like your computer's soundcard.
