Help! MK-171

Hi, I´m new here and I´ve just got the MK-171 kit…
I´ve made it and it goes on well, but I want it to be adapted to the microphone entrance of a table of mixtures by a “jack” and so, the kit does not go on well and has problems as it does strange noises and strange things… someone knows what I have to do?

greetings.

Hi again, finally I didn´t connect it to the mixtures´ table, but now I have another problem, is that the kit goes on well but suddenly the LD2 lights up and ALL stops working, I´ve looked through it and I don´t know what´s the problem, any idea?
