That's a good question. I think I would ask Behringer directly. The link below has tabs for FAQ (Answers) and a direct contact (Ask a Question). Maybe fire off a question to them in the "Ask a Question" tab and see what they say about your microphone.Please write back and let us know what they say. I'm sure others will run into this as well, because 5v and 12v supplies are common as well 15-30v.
