Before you do, you might want to check a few things. First, the most common thing to go wrong seems to be a bad XLR cable. We recommend testing your mic with several different cables and input devices or channels on your PA or mixer to rule those out as the problem.
If you just got your mic and you can’t get it to respond at all, make sure you are using phantom power. (more on that here). If the response just isn’t what you were expecting sonically, definitely check that the mic is facing the right way. (More on that here).
If none of that seems to help, definitely reach out! We want to make sure your mic is working great for you.
