When I plug in my Sony microphone into my mix-dj how do I get the mic to play through it????

I have the Phillips mix-dj and I plug in my ipad to this device I use the djay 2 on my ipad and play my mixes through the mix-dj sterio/dj top desk, however when I try to plug my Sony microphone into either the aux in or aux out it doesn’t work. How do I get the microphone to play? Or work through the mix dj?
