DJM 750 MK2 - mic to booth on and off?

 Hi 

I just ordered the 750 mk2 but i cant for the life of me find any info on the booth output. ie mic to booth 

Basically i would like the mic to also run into the booth output so i can use this for my streaming and mix recordings. 

Does it have a function like the djm800 where i can turn if off and on as that would really help here.

Thanks in advance
